Skin Membrane Tumor Lysate

Human skin tissue membrane protein lysate was prepared by isolating the membrane protein from whole tissue homogenates using a proprietary technique. The human skin tissue was frozen in liquid nitrogen immediately after excision and then stored at -70˚ C. 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 skin tissue membrane protein pattern on SDS-PAGE gel is shown to be consistent for each lot by visualization with coomassie blue staining. The isolated skin tissue membrane protein is then Western analyzed by either GAPDH or β -actin antibody to confirm there is no signal or very weak signal.

Store at 2-8˚ C for continuous use. For extended storage, freeze working aliquots at -70˚ C. Repeated freezing and thawing is not recommended. Under proper storage conditions the shelf life is half a year from the date of receipt.
