4-arm PEG-SCM

4-arm Poly(ethylene glycol) succinimidyl carboxymethyl ester

4-arm Poly(ethylene glycol) succinimidyl carboxymethyl ester (4-arm PEG-SCM) manufactured by SINOPEG is a high quality multi-arm PEG derivative with succinimidyl carboxymethyl ester at each terminal of the four arms connected to one pentaerythritol core. PEG-SCM is one type of PEG-NHS reagents. The total molecular weight of 4-arm PEGs is the sum of the molecular weight of all four arms.  4-arm PEG-SCM is available with molecular weight of 2K, 5K, 10K, 20K and 40K Da. Other MW may be available by custom synthesis. The packaging sizes are available for 1g, 10g and 100g. Please contact us for bulk and GMP grade PEGs pricing and packaging size.
