Delivering bioactive proteins into cells without carriers presents significant challenges in biomedical applications due to limited cell membrane permeability and the need for targeted delivery. Here. we introduce a novel copyright-free method that addresses these challenges by chemically modifying proteins with an acid-responsive cell-penetrating peptide (CPP) for selective intracell... https://www.alarecre.com/NFL-Jacksonville-Jaguars-Distressed-AirPods-Pro-2nd-Gen-Skin-p100281/
