    Notes: Abstract We examined the potential contribution of thromboxanes in human monocyte adherence to plastic. Monocyte adherence to plastic could be augmented by various stimuli including lipopolysaccharide, chemotactic peptide, and supernates of antigen-stimulated lymphocytes. Increments in monocyte adhesiveness were suppressed by inhibition of cyclooxygenase, thromboxane synthetase, or by antiserum to thromboxane B2. Neither prostaglandin E2 or F2α significantly affected baseline or lipopolysaccharide-stimulated monocyte adherence. Additional experiments confirmed incremental production of thromboxane B2 by monocytes after incubation with lipopolysaccharide. Thromboxane B2 itself did not stimulate monocyte adhesiveness. These data demonstrate that monocytes release thromboxane A2 following stimulation and suggest that thromboxane A2 may play a significant role in monocyte-substrate attachment.

    Notes: The two major polypeptides of erythrocyte membrane spectrin have been isolated by preparative polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulfate. The tryptic peptide maps of the two polypeptides have been prepared by thin-layer chromatography and electrophoresis. Radioactive peptides have been prepared by 14C-carboxymethylation and chloramine T-catalysed 125I iodination. Maps of both sets of peptides demonstrate a marked similarity between the two parent polypeptides.

    Notes: Horizontal two-dimensional polyacrylamide gel electrophoresis with immobilised pH gradients in the first dimension has been applied to the analysis of human skin fibroblast and muscle myoblast total cell proteins. Excellent two-dimensional separations of skin fibroblast proteins were obtained using pH 4-10 immobilised pH gradient gels with a long interelectrode distance (16 cm), but resolution was degraded, particularly of the more acidic proteins, by the use of shorter (10 cm) gels. Improved resolution of acidic and basic proteins was obtained using separate pH 4-7 and pH 7-10 immobilised pH gradient gels respectively in the first dimension. Two-dimensional protein maps of skin fibroblast proteins were visualised both by silver staining and by autoradiography of samples labelled synthetically with [35S]methionine. Horizontal two-dimensional electrophoresis, using pH 4-7 and pH 7-10 immobilised pH gradient gels in the first dimension, was applied to the analysis of protein samples from skin fibroblasts and muscle myoblasts dual-labelled synthetically with [35S]methionine and [75Se]selenomethionine in an attempt to identify sets of proteins specific to each cell type. In addition, two-dimensional maps or protein samples derived from normal individuals and patients with Duchenne muscular dystrophy were compared to search for protein changes associated with the disease state. Although sets of qualitative protein spot differences were observed by visual inspection of the two-dimensional gels, more rigorous qualitative and quantitative analysis of the patterns using a computerised analysis system will be required to obtain the maximum amount of information from these data.

    Notes: Protein profiles of skin fibroblasts labelled with [35S]-methionine from patients with Duchenne muscular dystrophy (DMD) have been compared with those of cells from normal individuals by isoelectric focusing on thin polyacrylamide gels containing denaturing and solubilising agents cast on silanized supports. The routine method of sample solubilisation used a mixture of 8 M urea and 2 % NP-40. The inclusion of sodium dodecyl sulphate (SDS) in the sample was found to result in removal of non-ionic detergent from the gel even if a competition step had been used. In the presence of SDS less material remained at the point of sample application with a concomitant increase in bands in the middle region of the gels. Gels containing a mixture of sulfobetaine and NP-40 were found to be inferior to those with 8 M urea and 2 % NP-40, and high levels of urea were found to precipitate the zwitterionic detergent. No consistent qualitative differences between normal and DMD patterns were observed using any of the solubilisation methods on pH 3 to 10 or pH 8 to 10.5 gels. In order to facilitate quantitative analysis by gel slicing techniques, a plastic sheet was developed which would reliably bind acrylamide in the presence of 8 M urea and 2 % NP-40. The quantitative analysis revealed significant differences between normal and DMD profiles, but the relevance of these changes to the disease state awaits further investigation.
