2-Arm PEG-COOH

Full Name: 2-arm Methoxypoly(ethylene glycol) carboxylic acid (Lysine) (MW: 2kDa, 5kDa, 10kDa, 20kDa, 40kDa)

Category: Tags: ,

2-arm Methoxypoly(ethylene glycol) carboxylic acid (Lysine) (2-Arm PEG-COOH) from Advanced BioChemicals (ABC) are high quality multi-arm PEG derivatives with two methoxyl PEG arms and one carboxyl group that can selectively reacts with amino group in the peptide coupling reagent such at NHS, DDC and EDC. The total molecular weight of 2-Arm PEGs is the sum of the molecular weights of all two arms.

Advanced BioChemicals (ABC) offer 2-Arm PEG-COOH with MW 2kDa, MW 5kDa, MW 10kDa, MW 20kDa and MW 40kDa, in 100mg, 500mg, 1g and 5g packing sizes. Different MW of 2-Arm PEG-COOH products may be available by custom synthesis, please contact us at sales@advancedbichemicals.com for a free quote.
