6-Arm-PEG-FA (MW 1000)

Description

6-Arm-PEG-FA MW 1000 6-Arm-PEG-Folate MW 1000 is a PEG derivative modified with Folic acid HY-16637 . Polyethylene glycol can increase solubility and stability and reduce the immunogenicity of peptides and proteins. It can also inhibit the nonspecific binding of charged molecules to modified surfaces. Folic acid -FA has a high affinity for folate receptors and can be used for cell membrane receptors for targeted drug delivery.
