I. [Product Description]
R8-PEG-TCO is an efficient organic intermediate based on the covalent connection of the targeting cell-penetrating peptide R8 and trans-cyclooctene (TCO) through polyethylene glycol (PEG). It combines biocompatibility and chemical modifiability and is widely used in the fields of bioconjugation and targeted carrier construction. Its core value lies in enhancing water solubility through the PEG segment and achieving rapid and highly specific click chemical reactions using the TCO group. It is a key module in the development of pharmaceutical intermediates and the design of catalytic reaction systems.
