6-Arm-PEG-FA (MW 10000)

6-Arm-PEG-FA (MW 10000) [6-Arm-PEG-Folate (MW 10000) ] is a PEG derivative modified with folic acid. Polyethylene glycol enhances solubility and stability, reduces immunogenicity of peptides and proteins, and inhibits nonspecific binding of charged molecules to modified surfaces. Folic acid (-FA) targets high-affinity folate receptors, facilitating receptor-mediated drug delivery.
