![]() ![]() A rudimentary model for the structure of basic protein dimer in myelin is presented. The regions of the myelin basic protein molecule involved in dimerization were also determined by similar cleavage of the cross-linked dimer. We found no evidence of intramolecular cross-links between the two peptides formed by N-bromosuccinimide cleavage or between the two peptides formed by cyanogen bromide cleavage of the basic protein monomer. In the absence of cross-linking reagent, it was shown by radioimmunoassay that small amounts of myelin basic protein dimer and the heterodimer were normally present in sodium dodecyl sulfate-polyacrylamide gels. Membrane proteins are extracted with a single step phase partition. In contrast, when the myelin membrane was dipersed in sodium dodecyl sulfate before the addition of cross-linking reagent, all the proteins remained essentially monomeric, with the exception of myelin basic protein which dimerized to some extent. Mammalian Protein Extraction Reagent found in: Novagen CytoBuster Protein. The remaining myelin proteins, including the major proteolipid protein, were cross-linked into very high molecular weight aggregates. The only other cross-linked product formed in the intact cat dorsal column was a heterodimer consisting of myelin basic protein and either the major or minor proteolipid protein. When intact cat dorsal column or isolated myelin fragments were treated with cross-linking reagents, up to 20% of the myelin basic protein dimerized. The near-neighbor relationships of proteins in the myelin membrane were examined using dinitrodifluorobenzene and other cross-linking reagents. Evaluation of a recombinant 27-kDa outer membrane protein of Coxiella burnetii as an immunodiagnostic reagent. Glycobiology and Extracellular Matrices For customers studying GPCRs and other membrane proteins, MembranePro™ is the ready-to-use system that delivers enriched, functional membrane proteins efficiently and reliably.References (hide) Ahn, Sharif, Chisholm, Pinto, Gujar, Lee: " Ras transformation results in cleavage of reticulon protein Nogo-B that is associated with impairment of IFN response." in: Cell cycle (Georgetown, Tex.), Vol.The transfer is allowed to proceed approximately 25% longer than typically employed in Western blotting protocols.An easy to follow protocol for cell lysis and preparation of samples for Western Blotting is included with the Transmembrane Protein Extraction Reagent, or can be downloaded in pdf format by clicking the manual tabs. For Western blots, transfer takes place in a transfer buffer with added SDS and reduced amounts of methanol. The supernatant is added to Laemmli Sample Buffer, which is heated, but not boiled, prior to the resolution in SDS-PAGE gels. ![]() Following membrane dissolution, brief centrifugation is used to remove cellular debris from a supernatant fraction that contains the extracted transmembrane proteins. In the second step, the Transmembrane Protein Extraction Reagent is added to dislodge cells from the cell culture dish and then to dissolve the cell membrane. The researcher first employs techniques described in the protocol manual to limit endocytosis and lysosomal targeting that may result in proteolytic cleavage of cytoplasmic domains of multi-membrane spanning proteins.
