Methoxy PEG NHS with Stable Linker

Linear NHS PEGs with Stable Linker from JenKem Technology are amine PEGylation PEGs.

JenKem Technology’s PEG NHS Esters with stable linkers such as M-SCM, M-SPA, M-SBA, M-SHA, M-SGA, M-SSA, are reactive towards the amine group of lysine(s).

Methoxy PEG Succinimidyl Carboxymethyl Ester (SCM) has the shortest hydrolysis half-life among JenKem’s NHS products, offering the fastest reaction time and selectivity. Methoxy PEG Succinimidyl Hexanoate (SHA) provides the longest hydrolysis half-life among the NHS products offered by JenKem Technology.  Glucose PEG NHA and Galactose PEG NHS are amine reactive towards amines of lysine(s) at pH 7-8 at room temperature in <1hr; the presence of the monosaccharide cap increases the selectivity of the PEGylation reaction. NHS PEGs with Stable Linker with molecular weights, branching, and functional groups not listed in our online catalog may be available by custom synthesis.
