M-PEG-SG: Methoxy PEG Succinimidyl Glutarate, MW 5000, MW 20000

methoxy peg succinimidyl glutarate, mw 5000            methoxy peg succinimidyl glutarate with superior quality specification of ≥95% substitution.

methoxy peg succinimidyl glutarate (methoxy peg sg) is a high quality amine reactive methyl ether nhs peg product from jenkem technology. methoxy peg sg is a degradable  peg with a cleavable ester linker between the peg polymeric chain and the nhs ester. linear nhs pegs with a cleavable linker (degradable pegs) are especially employed in controlled release drug development applications. methoxy peg succinimidyl glutarate reacts with the amine group of lysine(s) and n-terminal amines at ph 7-8, while the ester linkage is cleaved under regular ester cleaving reaction conditions. methoxy peg succinimidyl glutarate has a slightly longer hydrolysis half life compared to methoxy peg succinimidyl succinate. jenkem technology offers methoxy peg sg with mw 5000 da (m-sg-5000) and mw 20000 da (m-sg-20k), in 1g and 10g packing sizes.
