K562 Membrane Lysate

K562 (Human Chronic Myelogenous Leukemia; Bone Marrow) cell membrane protein lysate was prepared by isolating the membrane protein from whole tissue homogenates using a proprietary technique. The K562 (Human Chronic Myelogenous Leukemia; Bone Marrow) cell was frozen in liquid nitrogen immediately after excision and then stored at -70ºC. The membrane protein is provided in a buffer including HEPES (pH 7.9), MgCl2, KCl, EDTA, Sucrose, Glycerol, sodium deoxycholate, NP-40, and a cocktail of protease inhibitors. For quality control purposes, the isolated K562 (Human Chronic Myelogenous Leukemia; Bone Marrow) cell membrane protein pattern on SDS-PAGE gel is shown to be consistent for each lot by visualization with coomassie blue staining. The isolated K562 (Human Chronic Myelogenous Leukemia; Bone Marrow) cell membrane protein is then Western analyzed by either GAPDH or β-actin antibody to confirm there is no signal or very weak signal.
