PEG Linkers and PEGylation Reagents

Modifying a peptide to include polyethylene glycol (PEG) groups may improve solubility and bioavailability. Protein PEGylation can protect the protein from proteolytic degradation and increase its half-life in biological applications, decrease its antigenisity or...

Pseudoproline Dipeptides

Pseudoproline dipeptides contain oxazoles formed from serine or threonine. When treated with trifluoroacetic acid (TFA), the oxazoles are converted to serine or threonine. The oxazoles have structural similarities to proline, thus they are named pseudoprolines. Like...

Isoacyl Dipeptides

Isoacyl Dipeptides Isoacyl dipeptides are used to prepare desipeptides in which the peptide chain is attached to the side chain oxygen atom of serine or threonine residues instead of the alpha nitrogen. Depsipeptides are less prone to aggregation than their standard...
