Spleen Cytoplasmic Lysate (0.1 mg)

Human spleen tissue cytoplasmic protein lysate was prepared by isolating the cytoplasmic protein from whole tissue homogenates using a proprietary technique. The human spleen tissue was frozen in liquid nitrogen immediately after excision and then stored at -70˚C. The cytoplasmic protein is provided in a buffer including HEPES (pH 7.9), MgCl2, KCl, EDTA, Sucrose, glycerol, and a cocktail of protease inhibitors. For quality control purposes, the isolated spleen tissue cytoplasmic protein pattern on SDS-PAGE gel is shown to be consistent for each lot by visualization with coomassie blue staining. The isolated spleen tissue cytoplasmic protein is then Western analyzed by GAPDH antibody, and the expression level is consistent with each lot.
