Carboxyl-dPEG®4-(m-dPEG®x)3

Amount: 100mg

Item Name: Carboxyl-dPEG®4-(m-dPEG®4)3

Item #: 10412

Mol. Wt.: 1266.47;

single compound dPEG® Spacer is 43 atoms and 28 A

Product Features and Benefits: Amine reactive pegylation reagent with a tribranched dPEG®4 branch; activate carboxylic acid in situ Single compound; made synthetically from 99.5% pure tetraethylene glycol Imparts significant and surprising water solubility, and the modifier itself is non-immunogenic and non-toxic Potentially very useful as a specific drug/protein modifier to increase hydrodynamic volume Produces compounds with reduced aggregation, or surfaces with reduced non-specific binding Produces stable amide bond Activate in situ with EDC/NHS or other carbodiamide combinations, including DCC with NHS, HOBt or PFP. The tribranched dPEG® acid is highly methylene chloride soluble, the ideal solvent for the carobiamide activations OR use your favorite recipe.
