Reactivegroup: Biotin. Description: FA-PEG-BIOTIN is one of Biotin PEG derivatives that have a functional folic acid on oneterminus of PEG chain. Folic acid is also known as vitamin M, vitamin B9 orpteroyl-Lglutamic acid. Folic acid is an essential bioactive molecule fornumerous biological functions. It participates in the synthesis, repairing andmethylation of DNA as well as to act as a cofactor in many biological reactions.Folic acid functionalized biotin is able to recognize and bind to cell surfacefolate receptors. Meanwhile, Biotin tag in this molecule can be easily detectedby avidin, streptavidin or their conjugates. PEG linker between folic acid andbiotin offers good water solubility, flexible linker structure and enhancedactivity. Handlingand Use: FA-PEG-BIOTIN is sensitive to light and temperature. Forbest use, material should always be kept in low temperature in dry condition.Protect from light. Avoid frequent thaw and freezing. For moreinformation about using this product, StorageConditions： FA-PEG-BIOTIN should bestored at -20℃.Desiccate. Protect from light. Materials may be handled under inert gas forbest stability.
