产品说明:

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.

处理以及使用:

FITC-PEG-FA  需要一只保存在低温、干燥、避光的条件，使用时一定要注意温差，防止吸潮，纯品保存最佳。

储存条件：

FITC-PEG-FA 于-20℃干燥，避光保存.惰性气体保护最佳. 一年之后复测。
