HIV-TAT protein transduction domain (PTD) is a new kind of peptide that is responsible for transduction of proteins through the plasma membrane with high efficiency. Linked covalently to proteins, peptides, nucleic acid, it could transduce into nearly all kinds of cells and tissues with high efficiency and without any damages. In this study, we constructed the TAT-EDAG and TAT-GFP prokaryotic expression vectors and expressed soluble TAT-EDAG and TAT-GFP fusions in E. coli BL21 (DE3) successfully. By using the Ni-NTA-agrose purification system under the native condition we got the purified fusion proteins whose purification were higher than 90%. After desalting we found the TAT-GFP could transduced successfully into the mouse fibroblast cells and the TAT-EDAG could transduced into HL-60 cells in vitro. It will be useful to amplify the HSCs in vitro in the next step.
