Description:

HS-PEG-SH is one of Ponsure homobifunctional PEG derivatives with free thiol group on each terminus of the PEG. Thiols can react with a number of thiol reactive groups such as maleimide, iodoacetamide, pyridyldisulfide, etc. Thiol group also has high binding affinity to noble metal surface, such as gold and silver. Therefore, thiolated PEG can be used for gold or silver particle surface modification.

Handling and Use:

HS-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：

HS-PEG-SH should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after 12 months.
