Isothermal titration calorimetry is presented to be an excellent method of detecting lipid membrane solubilization upon the addition of detergents. As an example, the titration of the nan-ionic detergent C t2EOt, to the lipid POPC is studied. The main contribution to the measured titration heat is the detergent's enthalpy difference upon transfer between micelles and membranes. The detergent ad...
This study presents a comparative proteomic analysis of the membrane subproteome of whole Arabidopsis seedlings using 2% Brij-58 or 60% methanol to enrich and solubilize membrane proteins for strong cation exchange fractionation and reversed-phase liquid chromatography-tandem mass spectrometry (LC-MS/MS). A total of 441 proteins were identified by our Brij-58 method, and 300 proteins were detec...
Prostacyclin (PGI2) receptors have been identified on platelets and other tissues but their physicochemical properties remain unknown due to difficulties in obtaining active solubilized receptors. We evaluated the ability of several detergents to release the receptors from platelet membrane preparations. In contrast to the results of Dutta-Roy and Sinha (Dutta-Roy, A. K., and Sinha, A. K. (1987...
The plasma membrane ATP-phosphohydrolase (ATPase) from red beet (Beta vulgaris L.) storage tissue was solubilized with the zwitterionic detergent Zwittergent 3-14 from a plasma membrane-enriched fraction which was extracted with the anionic detergent, sodium deoxycholate. For both the extraction of extraneous proteins by deoxycholate and the solubilization of active plasma membrane ATPase by Zw...
As a result of genetic and immunological evidence, it is now well established that the induction of murine cytolytic T cells (CTL) depends upon the recognition of antigens which are gene products of the major histocompatibility complex (MHC) of the stimulating cell. A more detailed understanding of the molecular events involved in this specific recognition would be greatly aided by the ability ...
1. Adenylate cyclase activity of the washed 600g sediment of bovine corpus-luteum homogenate was solubilized by Lubrol-PX, Triton X-100 and digitonin. Digitonin was the least destructive of NaF-stimulated activity. 2. NaF, present in the solubilization medium together with MgSO4, increased the percentage yields of soluble activity from untreated 600g sediment and 600g sediment which had been pr...
The zwitterionic detergent 3-[(3-cholamidopropyl)-dimethylammonium]-1-propanesulfonate (CHAPS), derivative of naturally occurring bile salts, is widely used in biochemistry for membrane protein and receptor solubilization and purification. Since the efficiency of protein stabilization is known to be highly related to the detergent concentration, it is very important for the researcher to predic...
We have used proteinase K as a probe to detect cytoplasmically and luminally exposed segments of nascent polypeptides undergoing transport across mammalian microsomal membranes. A series of translocation intermediates consisting of discrete-sized nascent chains was prepared by including microsomal membranes in cell-free translations of mRNAs lacking termination codons. The truncated mRNAs were ...
Pluronic/bile salt/phospholipid mixed micelles (Pluronic/BS/PS-MM) drug carrier system for solubilization hydrophobic drugs was developed. A typical hydrophobic compound, pyrene, was selected as a representative hydrophobic compound to model the hydrophobic drugs. Five Pluronics, F68, F88, F98, F108, and F127 with different PPO chain length were studied. CMC data and solubilization capacities w...
