I. [Product Description]
R8-PEG-MTX is a polyethylene glycol-methotrexate complex modified with the targeting cell-penetrating peptide R8. As a high-purity organic intermediate, it can be applied in the fields of bioconjugation and carrier construction. Its core value lies in enhancing water solubility and stability through the PEG segment and achieving efficient transmembrane delivery with the help of the R8 cell-penetrating peptide. It is suitable for the preparation of pharmaceutical intermediates or the optimization of catalytic reaction systems.
