Folic acid is also known as vitamin M, vitamin B9 or pteroyl-L-glutamic 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. Thiol functionalized folic acid PEG allows the attachment of folic acid to gold nanoparticles or other molecules through its reaction to thiol reactive groups, such as maleimide. PEG linker bridged folic acid and thiol offers better water solubility, flexible linker structure and enhanced stability. Molecules or materials conjugated with PEG folic acid are useful for targeted drug delivery, cellular imaging and bioassay development. Handling and Use: FA-PEG-SH  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, .   Storage Conditions： FA-PEG-SH should be stored at -20℃. Desiccate. Protect from light. Materials may be handled under inert gas for best stability.   References： l  Advanced Therapeutics------A Tungsten Nitride‐Based O2 Self‐Sufficient Nanoplatform for Enhanced Photodynamic Therapy against Hypoxic Tumors. l  Analytical Chemistry(IF=6.042)-----A Functional Dual-Color Indicator to Achieve in situ Visualization of Intracellular Glycosylation.       Related Products: FA-PEG-NHS, FA-PEG-FITC FA-PEG-Maleimide ,FA-PEG-COOH FA-PEG-NH2,DSPE-PEG-FA This product is for research use only and is not intended for use in humans or for diagnostic use.
