Figure 3. Purification of rGIFT15.

Figure 3

Purification of His-MBP-GIFT15 on Nickel-Sepharose (A) and on DEAE-Sepharose (B) after cleavage with TEV protease. Black traces are the absorbance readings recorded at 280 nm and red traces represent the elution gradient. (C) SDS-PAGE following His-MBP-GIFT15 purification. (1) cell-free extract before induction with IPTG, (2) cell-free extract after induction with IPTG, (3) His-MBP-GIFT15 after Ni-Sepharose, (4) rGIFT15 after TEV protease treatment and isolation on DEAE-Sepharose, (5) molecular weight markers.
