Western Blot: EIF3B Antibody [NB100-93301] - Detection of Human and Mouse eIF3B/EIF3S9 by Western Blot (h&m) and Immunoprecipitation (h). Samples: Whole cell lysate from HeLa (5, 15 and 50 mcg for WB; 1 mg for IP, 20% of IP loaded), 293T (T; 50 mcg), and mouse NIH3T3 (M; 50 mcg) cells. Antibody: Affinity purified rabbit antieIF3B/ EIF3S9 antibody NB100-93301 used for WB at 0.04 mcg/ml (A) and 1 mcg/ml (B) and used for IP at 3 mcg/mg lysate. eIF3B/EIF3S9 was immunoprecipitated efficiently by rabbit antieIF3B/ EIF3S9 antibody NB100-93302, which recognizes a downstream epitope.
