6-Arm-PEG-FA (MW 1000)

6-Arm-PEG-FA (MW 1000) (6-Arm-PEG-Folate (MW 1000) ) is a PEG derivative modified with Folic acid, enhancing solubility and stability while reducing the immunogenicity of peptides and proteins. Polyethylene glycol (PEG) also inhibits nonspecific binding of charged molecules to modified surfaces. Folic acid (-FA) has a high affinity for folate receptors, making it suitable for targeted drug delivery to cell membrane receptors.
