4-arm PEG-NH2

4-arm Poly(ethylene glycol)aminemanufactured by SINOPEG is a high quality multi-arm PEG derivative with amine groups at each terminal of the four arms connected to one pentaerythritol core. Amine group can bind to carboxylic group or other amine reactive chemical groups. The total molecular weight of 4-arm PEGs is the sum of the molecular weight of all four arms. 4-arm PEG-NH2 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.
