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, 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。 文献引用： Acs applied materials&interfaces(IF=8.097)------ Folic Acid-Functionalized Hybrid Photonic Barcodes for Capture and Release of Circulating Tumor Cells. 类似产品推荐： 叶酸PEG活性酯，FA-PEG-NHS 叶酸PEG马来酰亚胺，FA-PEG-Maleimide 叶酸PEG巯基，FA-PEG-SH 叶酸PEG氨基，FA-PEG-NH2 叶酸PEG羧基，FA-PEG-COOH 二硬脂酰基磷脂酰乙醇胺PEG叶酸，DSPE-PEG-FA 备注：本产品仅供科研使用,不用于人体或诊断使用。
