Folic acid PEG Fluorescein, Folic acid PEG FITC, MW 2000
Description
Folic acid PEG Fluorescein, also called Folate PEG fluorescein, is one of Nanocs fluorescent folic acid PEG derivatives. Fluorescein is a bright green fluorescent dye with excitation/emission wavelength at 490 nm/520 nm. Fluorescent PEG can be easily traced with its fluorescent signal. Folic acid was covalently linked to PEG chain via its terminal carboxylic groups. 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. Folic acid is a ligand to folate receptors on cell surfaces. Fluorescein PEG folic acid is readily soluble in aqueous solution and it can be used to detect folate receoptors on cell membrane.

Description:
Carboxylic acid functionalized methoxyl polyethylene glycol, PEG acid (mPEG-COOH) is a mono reactive PEG derivative that can be used to modify proteins, peptides and other materials via amino or other acid reactive chemical groups. PEGylation can increase solubility and stability and reduce immunogenicity of peptides and proteins. It can also suppress the non-specific binding of charged molecules to the modified surfaces.
Physical Properties:
- Off-white/white solid or viscous liquid depends on molecule weight;
- Soluble in regular aqeous solution as well as most organic solvents;
Storage Conditions:
- Store at -20 0C, dessiccate. Protect from light. Avoid frequent thaw and freeze.
