Description:

BIOTIN-PEG-NH2 is one of Ponsure reactive biotinylation PEG derivatives that can be used to attach biotin tag to proteins, peptides, particles and other materials surfaces via its reactive amine group (-NH2). Amine group reacts readily with a number of amine reactive groups, such as succinimidyl ester (NHS), COOH, aldehyde, etc to form stable covalent bonds. Pegylated biotin has high affinity toward avidin or streptavidin. Biotin/avidin system has been used widely in biomolecule detection and separation. PEG linker between biotin and amine offers better water solubility, flexible linker structure and enhanced stability. More notably, Ponsure biotin PEG amine is water soluble, all reactions or assays can be carried out in aqueous buffer without need any organic solvents.

Handling and Use:

BIOTIN-PEG-NH2  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-NH2 should be stored at -20℃. Desiccate.  Materials may be handled under inert gas for best stability. Re-test material after 12 months.
