Chol-PEG-CYGRKKRRQRRR

Cholesterol-PEG-CYGRKKRRQRRR/CYGRKKRRQRRR-PEG-Cholesterol is a cholesterol modified TAT transmembrane peptide PEG derivative, belonging to the classic amphiphilic functional carrier material. As a modification component of drug delivery systems, it is used to construct pH sensitive targeted micelles for co delivery of siRNA, chemotherapy drugs, etc., to enhance the drug uptake efficiency of tumor cells. It can also modify carriers such as liposomes and nanoparticles to help large molecule drugs penetrate cell membranes and even nuclei, adapting to delivery needs such as gene editing tools and DNA vaccines.
