Biotin-PEG-Alk (MW 2000)

Description

Biotin-PEG-Alk MW 2000 is a biotin labeled PEG derivative. Biotin is an enzyme co-factor, can be used for labeling protein; PEG is a hydrophilic and water-soluble polymer with low toxicity; Alk Alkyne , acyclic branched or unbranched aliphatic hydrocarbon, can react with azido, which improve the efficiency of biotin binding targets. Biotin-PEG-Alk MW 2000 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition CuAAc with molecules containing Azide groups.
