Description:

Alkyne-PEG-MAL  is one of Ponsure   reactive Click Chemistry PEG crosslinkers that have a maleimide and an alkyne group on each PEG terminus. Click chemistry reaction between alkyne and azide is highly efficient. This reaction proceeds well in aqueous solution catalyzed by cooper ions. Reaction between alkyne and azide allows conjugation of maleimide PEG to correspondent molecules with high yield. Resulted maleimide group can react readily with available –SH groups from naturally occurring or mutagenically derived cysteine residues. This reaction proceeds readily at pH 6.5~7.5 to form a stable, non-cleavable thioether bond. PEG linker between alkyne and maleimide offers better water solubility, flexible linker structure and enhanced stability.

Handling and Use:

Alkyne-PEG-MAL  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：

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