Product Description
Cell penetrating peptide is a peptide that can penetrate cell membrane autonomously and has great application prospects in the medical field. KR-22 is a cell-penetrating peptide composed of 22 amino acids, which can carry multiple exogenous substances such as peptides, proteins, nucleic acids and nanoparticles into cells in a covalent or non-covalent manner. The amino acid in the KR-22 sequence contains a functional group that is positionally hindered. Such a structure will increase the difficulty of peptide synthesis. At the same time, there are not too many arginines in the KR-22 sequence. The isoelectric point is 11.57. When the pH value of the environment is When it is 7.4, the penetration ability of KR-22 reaches the maximum.
