This is a scrambled TAT-NSF222scr fusion polypeptide. It is composed of 11 amino acids from the cell permeable human immunodeficiency virus TAT polypeptide, 3 glycines as a linker, followed by scrambled N-Ethyl-maleimide-sensitive factor (NSF) D1 domain. This peptide is used as a control for the TAT-NSF222 peptide.
