Description:

FA-PEG-BIOTIN is one of Ponsure Biotin PEG derivatives that have a functional folic acid on one terminus of PEG chain. Folic acid is also known as vitamin M, vitamin B9 or pteroyl-Lglutamic acid. Folic acid is an essential bioactive molecule for numerous biological functions. It participates in the synthesis, repairing and methylation 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 surface folate receptors. Meanwhile, Biotin tag in this molecule can be easily detected by avidin, streptavidin or their conjugates. PEG linker between folic acid and biotin offers good water solubility, flexible linker structure and enhanced activity.
