The western blot (sometimes called the protein immunoblot), or western blotting, is a widely used analytical technique in molecular biology and immunogenetics to detect specific proteins in a sample of tissue homogenate or extract. Besides detecting the proteins, this technique is also utilized to visualize, distinguish, and quantify the different proteins in a complicated protein combination. Web[0038] Fig. 2F depicts a Western blot demonstrating rescue of endogenous GS protein levels in USP15-KO cells. USP15 +/+ and USP15~'~ 293FT cells were staved of glutamine for 24 h, and then pre-treated with 2 pM MLN4924 or 2 mM MSO for 30 min, followed by 4 mM glutamine treatment for 8 h.
