生物活性

TAT TFA (YGRKKRRQRRR) is derived from the transactivator of transcription (TAT) of human immunodeficiency virus (HIV-1) and is a cell-penetrating peptide. TAT can increase the yields and the solubility of heterologous proteins[1].

体外研究
(In Vitro)

TAT (YGRKKRRQRRR) represents amino acids 47-57 of the human immunodeficiency virus type I (HIV-1) TAT protein. The positively charged protein transduction domain of the HIV-1 TAT protein (TAT-PTD; residues 47-57 of TAT) rapidly translocates across the plasma membrane of living cells. TAT (YGRKKRRQRRR; TAT-PTD) can cross the hydrophobic lipid bilayer of a cell membrane simply by passive diffusion[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
