Description:

FITC-PEG-FA is one of Ponsure green fluorescent folate PEG derivatives that have excitation/emission wavelength at ~490 nm/~520 nm. Fluorescein labeled PEG folate is a linear molecule with folic acid attached to one terminus of PEG chain and a fluorescein dye linked to the other PEG terminus. 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 is a ligand to folate receptors on cell surfaces. With its strong fluorescence, Ponsure fluorescein PEG folate is an excellent fluorescent probe to target and detect folate receptors both in-vitro and in-vivo.

Handling and Use:

FITC-PEG-FA  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition. Protect from light.

 Avoid frequent thaw and freezing. For more information about using this product, visit www.ponsure.com.

Storage Conditions：

FITC-PEG-FA should be stored at -20℃. Desiccate. Protect from light. Materials may be handled under inert gas for best stability.
