Cell membrane preparations containing nicotinic AChRs that are ligand-gated ion channels that form pores in cells plasma membranes, mediating fast signal transmission at synapses. Nicotinic AChRs are involved in a wide range of physiological processes, and can be either neuronal or muscle-type. The membrane preparations we have developed are suitable for receptor binding assays in which muscle type nicotinic AChRs are needed. The membranes are tested in several functional binding assays and quality testing criteria to meet binding specifications.
Cell Membrane Preparation containing nAchR
Usages:
For enrichment of bacteria of cosmetics and disposable hygiene products.
Principle:
Casein peptone and soybean peptone provide the nitrogen source, vitamins, and growth factors; sodium chloride to maintain osmotic balance; dipotassium hydrogenphosphate as a buffer; lecithin and Tween 80 can neutralize preservatives and can play a dispersed material in the emulsion features, lecithin can neutralize quaternary ammonium salt, Tween 80 neutralizes phenols, hexachlorophene, formalin, a combination that can neutralize and ethanol.
