micro-chains on the surface of murine splenocytes are more heterogeneous on SDS-polyacrylamide gel electrophoresis than both secreted and intracellular micro-chains labeled with [(3)H]tyrosine. No difference in heterogeneity among cell surface, secreted, or intracellular L chains was detected. The possible role of carbohydrate in micro-chain heterogeneity is discussed.

morphological and electrophoretic analysis of the crystalline inclusions (parasporal crystals) of sporulated cultures of b. thuringiensis ssp. kumamotoensis dsm 6070 (bt 6070) was conducted via phase contrast and scanning electron microscopy and sodium dodecyl sulphate-polyacrylamide gel electrophoresis. the activity of the spore-crystal suspensions against house fly (musca domestica) larvae wa...

Our objectives were to determine if milk casein as a percentage of true protein (CN%TP) estimated by sodium dodecyl sulfate–polyacrylamide gel electrophoresis (SDS-PAGE) is equivalent CN%TP Kjeldahl, and the proportion (CN), proteolysis products (CNPP), serum (SP) from (TP) that goes into Kjeldahl noncasein nitrogen (NCN) filtrate stays in NCN precipitate using SDS-PAGE. Raw samples collected 1...

Genes encoding homologs of the gp91(phox) subunit of the plasma membrane NADPH oxidase complex have been identified in plants and are hypothesized to be a source of reactive oxygen species during defense responses. However, the direct involvement of the gene products in superoxide (O(2)(-)) production has yet to be shown. A novel activity gel assay based on protein fractionation in native or so...

Genes encoding homologs of the gp91 subunit of the plasma membrane NADPH oxidase complex have been identified in plants and are hypothesized to be a source of reactive oxygen species during defense responses. However, the direct involvement of the gene products in superoxide (O2 ) production has yet to be shown. A novel activity gel assay based on protein fractionation in native or sodium dodec...

We have fractionated tau isoforms by elution at increasing pH values using iron-chelated affinity chromatography, which discriminates between isoforms phosphorylated to different extents. Microtubule-associated tau elutes from the column at a pH gradient narrower than that of total brain tau. Neither under-phosphorylated nor highly phosphorylated isoforms are found in the microtubule-associated...

Heat-labile enterotoxins from Escherichia coli strains of human and porcine origins had identical subunit composition, arrangement, and size in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Immunological differences recently described by others were shown to reside exclusively in the B subunits.

A highly sensitive enzyme-linked immunosorbent assay was used for the analysis of serum IgG reactivity against specific immunogenic Treponema pallidum proteins. Outer membrane treponemal proteins purified by preparative SDS-polyacrylamide gel electrophoresis were used as antigenic probes at concentrations as low as 100 ng per ml (5 ng per well in microtitre plates). Detection of anti-treponemal...
