Description

Methoxy PEG Succinimidyl Succinate with superior quality specification of ≥95% Substitution.

JenKem Technology’s Methoxy PEG Succinimidyl Succinate (Methoxy PEG SS) is a high quality amine reactive NHS PEG product with degradable cleavable ester linker between the PEG polymeric chain and the NHS ester. Linear NHS PEGs with Cleavable Linker (degradable PEGs) are especially employed in controlled release drug development applications. Methoxy PEG Succinimidyl Succinate reacts with the amine group of lysine(s), or amines such as on the active ingredients of Adagen®, Peg-ademase, or PEG-adenosine deaminase, PEG aspargase, PEG-L-asparaginase, or related biosimilars, at pH 7-8, while the ester linkage is cleaved under regular ester cleaving reaction conditions. JenKem Technology offers Methoxy PEG SS with MW 5000 Da (M-SS-5000) and MW 20000 Da (M-SS-20K), in 1g and 10g packing sizes.

Different MW of Methoxy PEG Succinimidyl Succinate products may be available by custom synthesis, please email us at tech@jenkemusa.com for details on custom PEGs. Other linear NHS esters are available – please select other cleavable linker NHS PEGs; or stable linker NHS PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.

Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
