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.
D,L-Cystathionine dihydrochloride is an intermediate in the synthesis of cysteine, which acts from the isotype of cysteine-β-synthase (CBS) produced by leucine and serine. Derived from cysteine. DL-cysteine contains a cysteine (βC-S) carbon-sulfur bond.
(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.
