Experienced vector artists and infographic designers will find a noticeable lack of the more advanced tools found in Illustrator CC. For example, the current release of Affinity Designer does not include a perspective grid or column graph tool.


Recent updates to Affinity Designer integrated PANTONE color swatches and the ability to activate artboards. These improvements are indications that the developers at Serif understand the needs of professional designers and are working to meet those needs.


We have used in vitro selection to isolate minimal, high-affinity RNA ligands for the Rev protein of HIV-1. Sequence analysis reveals that the tightest binding aptamers exhibit some similarity to a Rev-binding element (RBE) localized within the Rev-responsive element (RRE), but also contain novel sequence and structural motifs. A short helical stem and bulged nucleotides (nt) CUC ... UYGAG that have no counterpart in the wild-type (wt) element contribute to high-affinity binding. We have designed and synthesized a short (37 nt) RNA molecule that incorporates this motif; this RNA ligand has from three- to fivefold tighter binding than the full-length wt element, and up to 16-fold tighter than minimal wt RBEs. A guanosine:guanosine pairing that is postulated to occur in the wt element has been altered to other base pairings in the context of our optimized minimal element. RNAs that contain non-Watson-Crick base pairings, that can be modeled as isosteric to the wt G:G pair, bind Rev up to 160-fold tighter than elements that contain canonical Watson-Crick pairings or non-isosteric mismatches. These results support the hypothesis that Rev recognizes structural features associated with a non-Watson-Crick base pair.


Designer Persona is the default workspace to create vector graphics. The workspace for the designer persona has tools for drawing shapes and curves, vector brushes, fill and stroke options, transparency controls, and place and crop tools for images. The Designer Persona is the most similar to Adobe Illustrator. A significant tool in both personas is the Pixel Preview button. This viewing tools instantly shows you how a vector graphic would look as a raster graphic in both normal and retina screens.


If as a designer, you work with clients that are always asking for Adoibe Illustrator source files, then Affinity Designer will not be of great help. If you can send PDFs of your designs, then Affinity Designer can give you everything you need.






I am not a professional graphic designer, but I do need to create graphics and make edits for use in my website design projects. Affinity Designer is fantastic for my needs. My graphic designer sends me logos and other graphics, which I often edit in the presence of my clients. The ability to see the changes to their logo eliminates a lot of back and forth, which saves me a lot of time. My clients are thrilled to see the changes to their logo in real-time, and we can resolve most design issues in minutes. I highly recommend Affinity Designer to anyone who is looking for an alternative to Illustrator.


In recent years\u2014and especially with the launch of Affinity Designer 2\u2014Serif has established itself as a vector to be reckoned with in the world of graphic design software. Affinity Designer's powerful features and competitive pricing make it a compelling option for both new and experienced designers. It now earns a spot next to Adobe Illustrator and CorelDraw as an Editors' Choice winner for the best graphic design software. Furthermore, if you\u2019re sick of signing your life away with dozens of software and services subscriptions, Affinity Designer will be a welcome relief and worth every penny. Just remember that when Serif launches the next high-level update, you\u2019ll need to pay for the upgrade.


Antibodies are a critical component of the humoral adaptive immune response for the neutralization and destruction of disease-causing molecules, viruses and cells. Upon initial exposure to a foreign antigen, the immune system mounts a diverse polyclonal B cell response, producing a repertoire of antibodies that recognize multiple overlapping and non-overlapping antigenic epitopes. Although these initial antibodies have low binding affinities, activated antibody-producing B cells undergo a conserved affinity maturation process through somatic hypermutation and clonal selection to generate antibodies with successively greater affinities1,2,3. Target neutralization and elimination is subsequently triggered through multiple tightly regulated processes, including protein-mediated and cell-mediated effector functions.


Non-IgG antibody subclasses bind to corresponding FcRs, including FcαRI (IgA), FcεRI and FcεRII/CD23 (IgE), FcµR (IgM), IgδR (IgD) and Fcα/µR (IgA/IgM). IgA has a key role in mucosal tissues by regulating the tolerance to and protection from exposure to antigens, food, commensal microorganisms and enteric pathogens, whereas IgE has a role in the host defence against parasites such as helminths and is known for its role in allergic reactions through the high-affinity binding to FcεRI of mast cells (Box 2). IgA immune complexes bind FcαRI expressed on myeloid cells (including neutrophils, eosinophils, monocytes and macrophages) through third-order avidity interactions. Indeed, IgA antibodies have been reported to recruit neutrophils through release of leukotriene B4 and induce ADCC of tumour cells via the FcαRI88,89,90,91,92. Neutrophil-mediated ADCC may be mediated through a process called trogocytosis, which involves a stepwise destruction of the plasma membrane and uptake of the resulting plasma membrane fragments93.


Fc domains are being engineered to enhance their binding affinity for immune effector molecules with the aim to decrease an activation threshold by increasing target occupancy at lower antibody densities or antibody immune complex concentrations, or by extending interaction times (owing to a decreased off-rate). The Fc regions of IgG subclasses differ in their affinity for C1q and their potency to activate complement (Box 2), and reshuffling of segments from different IgG subclasses has therefore proved to be a successful engineering strategy for increasing binding176,177,178,179. Several groups have enhanced C1q binding affinity and CDC by mutating amino acid positions in the Fc region, including amino acids at positions S267, H268, S324, K326, E333 (refs.180,181,182,183,184) (Fig. 4c, left). The affinity increase for C1q must be carefully tailored to retain a proper activation threshold in order to avoid unattended complement activation in the absence of avidity binding to antigen. In a comparison of affinity and avidity engineering, Tammen et al. demonstrated that complement-mediated tumour cell lysis was enhanced more effectively with mutations that enhanced on-target IgG hexamerization compared to mutations that enhanced monomeric IgG affinity for C1q, particularly against cells with low EGFR expression levels96.


Extensive mutational analyses have identified amino acid positions in the IgG Fc region that differentially affect binding to distinct FcγRs and that can be modified to enhance ADCC or ADCP activity185,186,187. S239D/I332E amino acid substitutions in the Fc domain of antibodies targeting EGFR, CD52 and CD20 were shown to enhance FcγRIIIA/FcγRIIB affinity and increase ADCC and ADCP185 (Fig. 4c, right). Glycoengineering the Fc region for reduced fucose content can also enhance effector function by improving binding to FcγRIIIA. Next to improving classical FcγR-mediated effector functions, enhancement of FcγR binding interactions may be used to increase the agonistic activity of immunomodulatory antibodies. For example, enhancing FcγR affinity using S267E/L328F or E233D/G237D/H268D/P271G/A330R Fc mutations was reported to increase the antitumour activity of DR5 and OX40 antibodies149,175,188,189,190. Further, selective enhancement of antibody binding to FcγRIIB has been leveraged to inhibit BCR-mediated B cell activation and suppress humoral immunity188,191, as well as enhance the clearance of immune complexes192.


The windows and rope stabilisers make the pen particularly useful when doing basic vector line work or creating custom live objects. Personally, I found the iPad a little small when editing specific nodes in paths; I regularly had to pinch to zoom. As such, more hardcore artists or designers would likely be better off investing in the larger 12.9-inch Pro. Considering how easy it is to migrate any project from Affinity Designer to the desktop Designer app, or Illustrator using iCloud, this is hardly a deal-breaker.


Protein-protein interactions (PPIs) trigger a wide range of biological signaling pathways that are crucial for biomedical research and drug discovery. Various techniques have been used to study specific proteins, including affinity chromatography, activity-based probes, affinity-based probes and photo-affinity labeling (PAL). PAL has become one of the most powerful strategies to study PPIs. Traditional photocrosslinkers are used in PAL, including benzophenone, aryl azide, and diazirine. Upon photoirradiation, these photocrosslinkers (Pls) generate highly reactive species that react with adjacent molecules, resulting in a direct covalent modification. This review introduces recent examples of chemical proteomics study using PAL for PPIs.


The visualization and monitoring of specific proteins without disturbing their biological function is a major challenge in chemical biology [1, 2]. To achieve the goals of this study, i.e., the localization and trafficking of a protein of interest (POI), researchers commonly use fluorescent labeling. This technique of genetically encoding fluorescent proteins (FPs) is broadly applied because of its intrinsic specificity [3, 4]. However, this method has some limitations, specifically the size of the green fluorescent protein (GFP) (ca. 30 kDa), which is sufficient to disturb the function and localization of the POI, and the fact that FPs can oligomerize [5]. As an alternative to this technique, chemical tags have been developed for the POI. The chemical tag method is similar to FP tagging. Different types of chemical tags have been developed to reduce the size of the tag. These chemical tags include fluorogenic bisarsenic tags, such as green fluorescent FlAsH and red fluorescent ReAsH tags [6, 7], as well as Halo-tag [8], SNAP-tag [9], CLIP-tag [10], BirA-tag [11, 12], APEX (enhanced ascorbate peroxidase) tag [13], TMP-tag [14, 15], His-tag [16,17,18]. A powerful alternative strategy to tagging is utilizing in situ photo-affinity labeling (PAL). PAL, or photocrosslinking, is a unique and emergent technique to study protein-protein interactions in the complex proteome. Upon photoirradiation, a photocrosslinking functional group generates highly reactive species that react with adjacent molecules, resulting in direct covalent modification (Table 1) [19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38]. Since PAL can capture noncovalent interaction partners spatio-selectively, photocrosslinking agents have emerged as a critical tool to study PPIs. Despite the significance, few photocrosslinkers are currently available, including benzophenone (BP), aryl azide (AA), and diazirine (DA).
