Membrane proteins are involved in diverse cellular processes and are an integral component of many signaling cascades, but due to their highly hydrophobic nature and the complexities associated with studying these proteins in planta, alternative methods are being developed to better characterize these proteins on a proteome-wide scale. In our previous work (Mitra, S. K.et al. J. Proteome Res. 2...
Potential interactions between membrane components of rat brain synaptic vesicles were analyzed by detergent solubilization followed by size fractionation or immunoprecipitation. The behavior of six synaptic vesicle membrane proteins as well as a plasma membrane protein was monitored by Western blotting. Solubilization of synaptic vesicle membranes in CHAPS resulted in the recovery of a large p...
the carrier facilitated transport of the lithium ions by a series of non-cyclic synthetic ionophores
the carrier facilitated transport of lithium picrate was studied using a series of non-cyclic polyethers containing different end groups and chain lengths through bulk liquid membrane (blm) and supported liquid membrane (slm) systems. the various membrane supports used are viz. ptfe, cellulose nitrate, and dialysis membrane and onion membrane. the amount of li+ transported depends upon the stru...
background and objectives: virosomes are virus like particles (vlp) assembled in-vitro. influenza virosomes maintain the cell binding and membrane fusion activity of the wild type virus but are devoid of viral genetic material or internal proteins. influenza virosomes mimic the natural antigen presentation route of the influenza virus. materials and methods: virosomes were prepared by membrane ...
The solubilization dynamics of dimyristoylphosphatidylcholine (DMPC) liposomes, as induced by sodium dodecyl sulfate (SDS), were investigated; this investigation was motivated by several types of atypical behavior that were observed in the solubilization in this system. The liposomes and surfactants were mixed in a microchip, and the solubilization reaction of each liposome was observed using ...
Liquid Membrane (LM) based processes, as Supported Liquid Membranes (SLMs), have been proposed, for over 30 years, as effective methods for the selective separation of inorganic/organic species from different water streams. The industrial use of SLMs has been limited mainly by their insufcient stability. To investigate on the main cause of system destabilization and the o...
The outer membrane fraction from Rhodopseudomonas sphaeroides was isolated by isopycnic density centrifugation. The purity of this fraction was assayed by several methods. When the outer membrane fraction obtained after French press lysis of cells was compared with the outer membrane fragments released during spheroplast formation, the polypeptide profiles were identical. Detergent solubilizati...
G protein-coupled receptors (GPCRs) are the largest class of molecules involved in signal transduction across cell membranes and are major drug targets. Since GPCRs are integral membrane proteins, their structure and function are modulated by membrane lipids. In particular, membrane cholesterol is an important lipid in the context of GPCR function. Solubilization of integral membrane proteins i...
this paper deals with the extraction of l-theanine containing aliquat 336 as a carrier and cyclohexane as solvent across bulk liquid membrane. the optimum operation condition are as follows: extraction time of 150 min, initial concentration of theanine in the feed phase is 1.8 g/l, the carrier concentration is 0.5 m, the ion of the receiving phase is 0.2 m nacl of na2hpo4-nah2po4 buffer solutio...
the kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (l) through a bulk liquid membrane is studied experimentally and theoretically. the proposed model is based on the assumption of a pure diffusion of the complex salt [k·l]+scn¯ through the liquid membrane stagnant films at the interfaces. it illustrates the connection between liquid-liquid extraction equilib...
