I. [Product Description]
Collagen-PEG-CTT2 is a targeted polypeptide complex based on the covalent modification of collagen and polyethylene glycol. As a high-performance organic intermediate, it is widely used in the modification of biomaterials and the construction of functional carriers. Its core value lies in achieving controllable self-assembly characteristics through precise regulation of the PEG molecular weight and enhancing the targeting recognition ability with the CTT2 polypeptide sequence. It is suitable for catalytic coupling reactions and the construction of complex molecular systems.
