An ECM Mimetic Library for Engineering Surfaces to Direct Cell Surface Receptor Binding Specificity and Signaling

The extracellular (ECM) microenvironment, defined by biochemical cues and physical cues, is a deciding factor in a wide range of cellular processes including cell adhesion, proliferation, differentiation, and expression of phenotype-specific functions. For this reason, engineering the ECM microenvironment provides

Signal Peptide Optimization: Effect On Recombinant Monoclonal IgG Productivity, Product Quality And Antigen-Binding Affinity

A signal peptide is a 5-30 amino acid (aa) peptide present at the N-terminus of secretory proteins.

Cell and Organelle Labeling with Fluorescent Antibodies

The Human Protein Atlas Program has carefully selected three different human cell lines, A-431 epidermoid carcinoma, U-251 MG glioblastoma and U-205 osteosarcoma, for organelle mapping of the proteome. As Prestige Antibodies are studied by immunofluorescence (IF) staining, three well-characterized organelle

GlycoProfile™ ß-Elimination Kit

Our's GlycoProfile Beta-Elimination Kit allows researchers to perform complete glycoproteomics research by preserving both the O-glycans and protein, specifically remove o-glycans, label o-glycans prior to analysis, have confidence in uniformity of procedure. While it is known that O-glycosylation plays

Biotinylated Peptides

Our Streptavidin HC (High-Capacity) multiwell plates are prepared with a highly-porous, high-density streptavidin coating. Streptavidin has similar biotin-binding characteristics as avidin. Streptavidin can bind 4 moles of biotin per mole of protein with high selectivity and affinity (Kd~10-15). Unlike avidin

Enzymes for Antibody Characterization

Antibodies now make up the fastest growing category of therapeutic drugs

Post Translational Modification

Post-translational modifications such as glycosylation, phosphorylation, and sulfation, to name a few, serve many functions. As a result, the analysis of proteins and their post-translational modifications is particularly important for the study of diseases where multiple genes are known to

Chiral Amines in Asymmetric Synthesis

Chiral amines have found widespread application in asymmetric synthesis serving, for instance, as chiral bases in enantioselective deprotonation reactions or being valuable substances for resolving racemic mixtures of acids.

Cleavage and Purification of GST-Tagged Protein Bound to GSTrap

This page shows how to cleave and purify GST-tagged proteins bound to GSTrap from Cytiva.

Unnatural Amino Acids for Peptide Synthesis

Unnatural amino acids, the non-proteinogenic amino acids that either occur naturally or are chemically synthesized, are becoming more and more important as tools for modern drug discovery research.

Degrader Building Blocks for Targeted Protein Degradation

Protein Degrader Building Blocks are a collection of crosslinker-E3 ligand conjugates with a pendant functional group for covalent linkage to a target ligand.

Proline Derivatives and Analogs

Proline analogues are promising candidates for tuning the biological, pharmaceutical, or physicochemical properties of naturally occuring, as well as de novo designed, linear, and, cyclic peptides.

N-Linked Glycans Overview

N-linked glycosylation, modification, and degradation

O Linked Glycans

O-Linked glycans are usually attached to the peptide chain through serine or threonine residues. O-Linked glycosylation is a true post-translational event and does not require a consensus sequence. The most common type of O-linked glycans contain an initial GalNAc residue

Introduction to Proximity Labeling

A novel method has been developed to tag antibodies with a photoreactive iridium catalyst. Light activates the catalyst to convert a diazirine compound into a reactive carbene intermediate that can label membrane proteins in close proximity. The diazirine adds a

Strategies for Deglycosylating N-Linked Glycans

Explore various strategies for deglycosylating N-linked glycans involving PNGase F, PNGase A (Glycopeptidase A), and even native and sequential deglycosylation with endoglycosidases like Endoglycosidase H, Endoglycosidase F, and exoglycosidases.
