I. [Product Description] 
R8-PEG-TZ is a polyethylene glycol-tetrazine complex modified with the targeting cell-penetrating peptide R8. As a high-purity organic intermediate, it is widely used in the fields of bioconjugation and molecular probe construction. Its core value lies in providing an efficient catalyst platform for the precise synthesis and functional modification of complex molecular systems through the cell-penetrating property of the R8 cell-penetrating peptide, the biocompatibility of the PEG chain, and the high-efficiency click chemical reactivity of tetrazine.
