Description:

BIOTIN-PEG-Alkyne is one of Ponsure Click Chemistry PEG reagents that contain a terminal biotin and an alkyne group on each PEG terminus. Alkyne group is one of most commonly used Click Chemistry functional group that can react with azide group. Reaction between alkyne and azide proceeds easily in aqueous solution catalyzed by cooper ions. High yield reaction of alkyne and azide enables the conjugation of biotin tag to targeted molecules efficiently. Biotin is a commonly used bioactive tag that can bind to avidin or streptavidin with high affinity. Biotin/streptavidin system has been used widely in bioassay development, protein and nucleic acid detection and separation. Alkyne functionalized biotin PEG allows biotinylation of various substrates with high yield. PEG linker between alkyne and biotin group offers good water solubility, flexible spacer length and enhanced stability.

Handling and Use:

BIOTIN-PEG-Alkyne  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition.
