DSPE-PEG-Biotin, MW 2,000 represents a phospholipid PEG polymer with biotin that binds strongly to avidin or streptavidin for protein labeling or purification. It forms lipid bilayers in water and can be used for drug encapsulation in liposomes or nanoparticles. The 2k polyPEG units enhance the hydrophilicity of the molecule.
