Biotin-TAT (47-57) links a biotin tag to the cationic cell-penetrating TAT(47-57) sequence. The construct facilitates affinity-based capture and visualization of peptide uptake. Its arginine-rich motif promotes interaction with cellular membranes and biomolecular surfaces. Researchers employ it in delivery pathway studies, pull-down assays, and transport mechanism analysis.
