It has been demonstrated that ACh receptors in Xenopus nerve-muscle cultures migrate in the membrane to the nerve contact area during junction formation (Anderson et al., 1977) and that "diffusion trapping" is the major mechanism for nerve-induced receptor accumulation (Kidokoro and Brass, 1985; Kuromi et al., 1985; Kidokoro et al., 1986). A crucial(More)
Endo-β-galactosidase from Escherichia freundii cleaves polylactosaminyl structures as follows: R-GlcNAcβ1-3Galβ1-4GlcNAcβ1-R′ + H2O → R-GlcNAcβ1–3Gal + GlcNAcβ1-R′. By staining with Griffonia simplicifolia agglutinin-II following the enzyme digestion, the distribution of R-GlcNAcβ1–3Galβ1–4GlcNAc can be demonstrated in tissue sections. This carbohydrate(More)
Blood group ABH and related antigens are expressed not only in red blood cells but also abundantly in many epithelial cells of human and other vertebrate species. Recent electron microscope observations have revealed the precise distribution of these antigens in various cellular constituents such as the Golgi complex, cell membrane, mucous granules and(More)
Using immunostaining with monoclonal antibodies (mAbs) from three different sources as well as anti-B lectin, GSAI-B4 staining and α-galactosidase digestion, blood group B antigens were localized and analysed in tissue sections of sublingual glands from blood group B and AB individuals. Quantitative analysis of galactose was simultaneously carried out on(More)
