Biotin-TAT (47–57)（Cat No.:I044293）is a synthetic peptide derived from residues 47 to 57 of the HIV-1 TAT protein, a well-known cell-penetrating peptide (CPP). This sequence, typically YGRKKRRQRRR, enables efficient transport of biomolecules across cellular membranes. The biotin label allows for easy detection, purification, or conjugation via high-affinity binding to streptavidin. Biotin-TAT is widely used in drug delivery, imaging, and molecular biology to facilitate intracellular delivery of proteins, nucleic acids, or nanoparticles. Its dual functionality enhances research into cellular uptake mechanisms and targeted therapeutic applications across various biomedical fields.
