Mal-amido-PEG24-TFP ester - 95%, high purity , CAS No.1431295-77-0
Basic Description Specifications & Purity 95% Storage Temp Store at -20°C Shipped In Ice chest + Ice pads Product Description Mal-amido-PEG24-TFP ester is PEG derivative containing a maleimide and TFP ester end group. Maleimide groups are reactive with thiols between pH 6.5 and 7.5. The TFP ester can be reacted with primary amine groups and is also less susceptible to undergo hydrolysis compared to NHS ester. The hydrophilic PEG chains increase the water solubility of a compound in aqueous media. Longer PEG chains have improved water solubility relative to shorter PEG chains.
