DMABA Derivatization: Aminophospholipid Detection Multiplexing
In this video Dr. Robert Murphy, professor at University of Colorado - Denver, discusses DMABA Derivatization: Aminophospholipid Detection Multiplexing.
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.
EX-CELL® Glycosylation Adjust (GAL+)
Our protein quality supplement, EX-CELL® Glycosylation Adjust (Gal+), provides customers with a novel chemically defined product which targets glycosylation attributes.
N-Linked Glycans Overview
N-linked glycosylation, modification, and degradation
Methods and Matrices for Mass Spectrometry of Glycans
Glycosylation is known to have profound influence on various physiochemical, cellular and biological functions of proteins. Alterations in this modification are known to affect the immune system and have been associated with various pathological states such as cancer, rheumatoid arthritis
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
Peptide Stability
When selecting peptides for custom synthesis, several important factors should be considered during the design process. These considerations include sequence length, solubility and sequence stability.
Glycoprotein Deglycosylation
Information about Glycoprotein deglycosylation. The diversity of oligosaccharide structures, both O-linked and N-linked, often results in heterogeneity in the mass and charge of glycoproteins.
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.
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
Peptidoglycan Structure, Biosynthesis and Function
The basic structure of peptidoglycan (PGN) contains a carbohydrate backbone of alternating units of N-acetylglucosamine (GlcNAc) and Nacetylmuramic acid, with the N-acetylmuramic acid residues cross-linked to peptides.
Glycosyltransferases were initially considered to be specific for a single glycosyl donor and acceptor, which led to the one enzyme-one linkage concept. Subsequent observations have refuted the theory of absolute enzymatic specificity by describing the transfer of analogs of some
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
ChiPros Chiral Amines
Chiral amines play an important role in stereoselective organic synthesis. They are used directly as resolving agents, building blocks, or chiral auxiliaries.
