Description:

Biotin-PEG-SH  is one of Ponsure thiolated biotin polyethylene glycol derivatives that have a free thiol group on the one end of PEG chain and a biotin molecule on the other PEG terminus. Biotin is a bioactive small molecule that has high affinity to avidin or streptavidin. Thiol or sulfhydryl group reacts readily with many thiol reactive groups, such as maleimide, haloacetyl or pyridyldisulfide. It can also bind to gold and other noble metal surface with high affinity. Reactions between thiol and other groups thus allow the conjugation of biotin to proteins, antibodies, peptides, particles and other materials surfaces quickly and specifically. PEG linker between biotin and thiol groups offers better water solubility, flexible linker structure and enhanced stability.

Handling and Use:

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

 Avoid frequent thaw and freezing. For more information about using this product, visit www.ponsure.com.

Storage Conditions：

Biotin-PEG-SH should be stored at -20℃. Desiccate. Protect from light. Materials may be handled under inert gas for best stability.
