I. [Product Description]
This product is an organic intermediate modified with polyethylene glycol (PEG) based on the cell-penetrating peptide Pep-1 (CGEMGWRC) and trans-cyclooctene (TCO). It has high biological compatibility and controllable coupling activity, and is suitable for bioorthogonal reaction systems and the construction of targeting molecules. Its core value lies in providing a stable coupling platform, which can be used as a pharmaceutical intermediate or a catalyst carrier to meet various functional modification requirements.

II. [Product Details]
