MAL-dPEG®24-Tris (-dPEG®24-Tris (m-dPEG®24)3)3, product number 11487, is a sulfhydryl-reactive, multibranched, monodispersed PEG product. The product is built around tris. One arm terminates in a maleimide group that reacts selectively with free thiols in a click chemistry type of reaction. Nine branches terminate in methyl groups. The amphiphilic PEG imparts tremendous water solubility to conjugate molecules and expands their hydrodynamic volume sufficiently to eliminate the renal clearance of the conjugates.
