Bis-propargyl-PEG9 is crosslinking reagent containing two propargyl groups. These functional groups enable the formation of triazole linkages with azide-bearing compounds with the presence of copper catalyst. The hydrophilicity of the molecule is improved because of the PEG chain. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Amine-PEG4-Amide-Tri(3-methoxypropanamide-PEG10-Propargyl) Methane HCl salt is a crosslinker consisting of an amino group with three propargyl groups. The amino group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde), etc. The propargyl groups can form triazole linkage with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. Reagent grade, for research use only.

Protease K is a serine protease with high enzymatic activity and wide substrate specificity. It can preferentially decompose ester and peptide bonds adjacent to the ends of hydrophobic amino acids, sulfur-containing amino acids and aromatic amino acids C, and is often used to degrade proteins to produce short peptides. It has the typical catalytic triad Asp39-His69-Ser224 characteristic of serine proteases and two Ca2+ binding sites around the active center increase its stability, allowing it to maintain high enzyme activity under a wider range of conditions.
