This receptor may act in concert with the conventional EcR in 20E-dependent programmed cell death of these glands. We report here, for the first time, the solubilization of mEcR from ASG membranes using the zwitterionic detergent CHAPS in the presence of NaCl. Our results show by ligand binding assay that mEcR solubilized this way is functionally active and retains 75% of its native binding activity. We also defined experimental conditions that yielded protein/detergent complexes with partial binding activity, which makes it possible to purify the membrane-bound ecdysone binding protein. © 2007 Zoological Society of Japan.}, pages = {971--977}, title = {Solubilization of the ecdysone binding protein from anterior silk gland cell membranes of the silkworm, bombyx mori}, volume = {24}, year = {2007} }
