Cys-TAT(47-57) (Cys-[HIV-Tat (47-57)]) is an arginine-rich cell-penetrating peptide derived from the HIV-1 transactivating protein, corresponding to the protein transduction domain of the TAT protein.
(Cys47)-HIV-1 tat Protein (47-57) possesses membrane translocation functionality and can serve as a surface derivatization agent for magnetic pharmaceuticals, thereby enhancing their uptake into specific target cells.
TAT (48-57) is a cell-permeable peptide derived from the HIV-1 transactivator of transcription (Tat) protein, encompassing amino acid residues 48 to 57 from the basic domain of HIV Tat.
Biotin-TAT (47-57) is a biotin-tagged transactivator of transcription, commonly employed as a protein transduction domain (PTD) in various primary cells. Its transduction capacity is contingent on ATP and temperature, suggesting the participation of endocytosis.
