Small Intestine Membrane Lysate

Human small intestine tissue membrane protein lysate was prepared by isolating the membrane protein from whole tissue homogenates using a proprietary technique. The human small intestine 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 small intestine tissue membrane protein pattern on SDS-PAGE gel is shown to be consistent for each lot by visualization with coomassie blue staining. The isolated small intestine 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.
