The presented data provides additional information about the assessment of affinity purified nicotinic acetylcholine receptor (nAChR) rich membrane solubilized with long chain (16 saturated carbons) lysophospholipid with glycerol headgroup (LFG-16).The assessment of stability and functionality of solubilized membrane protein is a critical step prior to further crystallization trails.One of the key factors for this task is the appropriate choice of a Hip Chairs detergent that can support nAChR activity and UHF Transceivers stability comparable to the crude membranes.The stability of the nAChR-LFG-16 complex incorporated into lipid cubic phase (LCP) was monitored for a period of 30 days by means of fluorescence recovery after photobleaching (FRAP) and the functionality was evaluated after its incorporation into Xenopus oocyte by means of the two electrode voltage clamp technique.
