What is H2N-PEG4-Propyne?
Description
Propargyl-PEG4-amine has a propargyl group and an amine group. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls, etc. The propargyl group can form triazole linkage with azide-bearing biomolecules.
The Uses of H2N-PEG4-Propyne
1-Amino-3,6,9,12-tetraoxapentadec-14-yne is used as a acetylene containing reagent with PEG spacer and carboxyl reactivity. The hydrophilic PEG spacer adds to the water solubility of this reagent, allowing for easy modification of carboxylic acid containing biomolecules such as antibodies, proteins and peptides with the terminal alkyne. The PEG spacer also reduces aggregation of modified proteins stored in solution by adding hydrophilic character.
