Description:

BIOTIN-PEG-MAL  is one of Ponsure  thiol (-SH) reactive PEG biotin derivatives that can be used to attach biotin molecule to proteins, peptides, particles and other materials surfaces through their reactive maleimide groups. Biotin is a small bioactive molecule that has high affinity toward avidin or streptavidin. Biotin/streptavidin system has been widely used in molecule detection, bioassays and drug delivery applications. Maleimide reacts readily with reduced sulfhydryl group from naturally occurring or mutagenically derived cysteine residues. This reaction proceeds readily at pH 6.5~7.5 to form a stable thioether bond. PEG linker between biotin and maleimide group offers better water solubility, flexible linker structure and enhanced stability. 

Handling and Use:

BIOTIN-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：

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