Heterofunctional Peg

Used for long-acting pegylation of biopharmaceuticals.
Linear structure, holds same functional groups in both ends, improve the pegylation efficiency on protein drugs. Including:

Mal-peg-mal -dimaleimidyl poly(ethylene glycol)]
Sc-peg-sc -disuccinimidyl poly(ethylene glycol)]
Ma-peg-ma -dimethacryloyl poly(ethylene glycol)]
Aa-peg-aa -diacryloyl poly(ethylene glycol)]
Eo-peg-eo -diglycidyl poly(ethylene glycol)]
Alkyne -peg- alkyne -diallyl poly(ethylene glycol)]
N3-peg-n [, -diazido poly(ethylene glycol)]
Ocn-peg-nco -diisocyanato poly(ethylene glycol)]
Ohc-peg-cho -diformyl poly(ethylene glycol)]
Hs-peg-sh -dimercapto poly(ethylene glycol)]
H2n-peg-nh2 -diamino poly(ethylene glycol)]
Hooc-peg-cooh --dicarboxyl poly(ethylene glycol)]
Ho-peg-oh [poly(ethylene glycol)]

Used for long-acting of pegylation of biopharmaceuticals. Possess two or more functional terminals, most common multi-arm peg including 3-arm peg, 4-arm peg, 8-arm peg. Multi-arm peg has larger molecular weight and special molecular shape, increase molecular weight greatly, and could retain the drug biological activity better. Includings:
2-arm peg-nhs [2-arm methoxypoly(ethylene glycol) succinimidyl ester (lysine)]
2-arm peg-cooh [2-arm methoxypoly(ethylene glycol) carboxylic acid (lysine)]
4-arm peg-sh [4-arm poly(ethylene glycol) thiol]
4-arm peg-sc [4-arm poly(ethylene glycol) succinimidyl ester]
4-arm peg-ma [4-arm poly(ethylene glycol) methacrylate]
4-arm peg-mal [4-arm poly(ethylene glycol) maleimide]
4-arm peg-nco [4-arm poly(ethylene glycol) isocyanate]
4-arm peg-eo [4-arm poly(ethylene glycol) glycidyl ether]
4-arm peg-cooh [4-arm poly(ethylene glycol) carboxylic acid]
4-arm peg-n3 [4-arm poly(ethylene glycol) azide]
4-arm peg-nh2 [4-arm poly(ethylene glycol) amine]
4-arm peg-alkyne [4-arm poly(ethylene glycol) alkyne]
4-arm peg-aa [4-arm poly(ethylene glycol) acrylate]
4-arm peg-cho [4-arm poly(ethylene glycol) aldehyde]
4-arm peg-oh [4-arm poly(ethylene glycol)]

Used for long-acting of pegylation of biopharmaceuticals. Special v¡± shape, connected by ether bond. Avoid instability caused by carbamate ester bond, also shorten the reaction period. It is one of our star products.
