PEGylation Reagents 

Activated linear and branched derivatives of polyethylene glycol (PEG) for pegylation and PEG-modification of peptides and proteins via primary amines and sulfhydryl groups to increase solubility, prolong stability and reduce immunogenicity.




Methyl-PEG-NHS-ester reagents for PEGylation of proteins and molecules having primary amines. Also called MS(PEG)n, where n = 4, 8, 12 or 24 polyethylene glycol units. 
 

A branched Methyl-PEG-NHS-ester reagent for PEGylation of proteins and molecules having primary amines. Also called TMS(PEG)12 or (Methyl-PEG12)3-PEG4-NHS Ester. 
 

Methyl-PEG-Maleimide reagents for PEGylation of proteins and molecules having free sulfhydryl groups. Also called MM(PEG)n, where n = 12 or 24 polyethylene glycol units. 
 

A branched Methyl-PEG-Maleimide reagent for PEGylation of proteins and molecules having free sulfhydryl groups. Also called TMM(PEG)12 or (Methyl-PEG12)3-PEG4-Maleimide. 
 

PEG amino acids, also called CA(PEG)n, where n = 4, 8, 12 or 24 polyethylene glycol units. The PEGylation compounds can be conjugated to molecules or surfaces using the crosslinker EDC or incorporated into AA sequences during peptide synthesis. 
 

Also called MA(PEG)n, where n = 4, 8, 12 or 24 polyethylene glycol units. Amino terminus of each PEGylation compound can be conjugated to molecules or surfaces using crosslinkers such as EDC.
