    Occurrence, distribution and nature of neuropeptide Y in the rat pancreas (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1554-1557 
    Details
    ISSN: 1420-9071
    Keywords: Immunocytochemistry ; neuropeptide Y ; radioimmunoassay ; rat pancreas

    Topics: Biology , Medicine
    Notes: Summary Significant quantities of a newly discovered peptide, neuropeptide Y, were found in the rat pancreas, where they were localized to nerves in the exocrine parenchyma and around arterial and ductal structures. Although unaffected by surgical parasympathectomy, the periarterial and periductal nerves were abolished by chemical sympathectomy, suggesting that NPY is partially costored with sympathetic transmitters in nerve fibers.

    Immunocytochemical demonstration of calmodulin in cells secreting by exocytosis (1985)
    Springer
    Cellular and molecular life sciences 41 (1985), S. 1340-1342

    ISSN: 1420-9071
    Keywords: Immunocytochemistry ; calmodulin ; secretory granules

    Topics: Biology , Medicine
    Notes: Summary Calmodulin is a regulator of several calcium-dependent cellular processes. It has been suggested that it plays a role in the mechanism of secretion. Employing an indirect immunoperoxidase technique at the light microscope level, this study demonstrates the presence of calmodulin in several exocytotic cells (mast cells, thyroid follicular cells, neurohypophyseal neurosecretory terminals, pancreaticβ-cells and pancreatic acinus cells) in rat and man. The positive staining reaction for calmodulin was granular and at least in the case of rat mast cells it appeared to be associated with the granule membrane.

    Demonstration of enamel matrix proteins on root-analogue surfaces of rabbit permanent incisor teeth (1977)
    Springer
    Calcified tissue international 24 (1977), S. 223-229

    Topics: Biology , Medicine , Physics
    Notes: Summary The continuously erupting rabbit incisor tooth is normally thought of as having an enamel covered “crown” on its labial surface and a cementum covered “root” on its lingual surface. We have examined both surfaces of continuously erupting rabbit incisor teeth taken from near term embryos by a variety of means, including transmission and scanning electron microscopy, biochemical fractionation, and immunohistochemistry. In all cases, we could detect no qualitative difference in the early extracellular matrices taken from the labial and lingual surfaces of the teeth. Both matrices were shown to be composed of dentin and enamel, although the thickness and geometry of the enamel matrix on the lingual surface was somewhat different from that on the labial surface.

    Notes: Abstract Xanthine dehydrogenase (XDH, EC 1.2.1.37) was purified from root nodules of soybean (Glycine max) and used to prepare a polyclonal rabbit antiserum. Monospecificity of this antiserum was ascertained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of the immunoprecipate. During root nodule development of soybean, only one form of XDH was detected on an immunological basis. Titration of XDH by immunoelectrophoresis showed that a remarkable increase in the amount of XDH occurred between two and four weeks after inoculation, in parallel with the increase in enzyme activity. Localization of XDH by immunofluorescence indicated that the enzyme was present exclusively in uninfected cells where it appeared to be associated with discrete organellels

    Phytochrome photoreversibility: Empirical test of the hypothesis that it varies as a consequence of pigment compartmentation (1978)
    Springer
    Planta 141 (1978), S. 129-134

    ISSN: 1432-2048
    Keywords: Avena ; Immunocytochemistry ; Phytochrome
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Phytochrome of oat (Avena sativa L., cv. Garry) coleoptile cells in the red-light-absorbing form, Pr, is diffusely distributed while after conversion to the far-red-light-absorbing form, Pfr, it is observed only in very small areas within the cell. Comparison of phytochrome photoversibility measurements to the distribution of the pigment within the cell indicates that the spectral assay is not influenced by the observed compartmentalization of the chromoprotein. However, the observed compartmentalization of phytochrome is correlated with a loss in spectrophotometrically detectable Pr.

    Extracellular protein fibrils in Chrysochromulina breviturrita (Prymnesiophyceae) and their serological relationship to fungal fimbriae (1986)
    Springer
    Archives of microbiology 146 (1986), S. 207-213 
    Details
    ISSN: 1432-072X
    Keywords: Extracellular proteins ; Surface fibrils ; Algae-fungi-Chrysochromulina ; Immunocytochemistry ; Agglutination ; Fimoriae
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract An extensive network of extracellular fibrils was revealed by negative staining in the greenish gold algal flagellate, Chrysochromulina breviturrita. These fibrils were of uniform diameter (4–5 nm), sometimes exceeding 5 μm in length. In addition there were short, narrower fibrils (2–3 nm) on the surface of the flagella. Six protein bands were isolated from spent culture medium by SDS-PAGE and one of 80,000 Da was found to polymerize after dialysis into 4–5 nm fibrils identical to those found on the cell surface. Two other proteins of 58,000 Da and 65,000 Da also formed 4–5 nm fibrils but these were either rare or of a shorter length and different appearance. An antiserum directed against the surface 7 nm fibrils (fimbriae) of fungi agglutinated cells of C. breviturrita and some other Prymnesiophyceae and Chrysophyceae, but did not agglutinate cells of algal species in other groups. Immunofluorescence and protein A gold labelling confirmed that antigens related to fungal fimbriae were present on the surface of cells of C. breviturrita. Only the 80,000 and 58,000 Da proteins labelled heavily following protein A gold labelling. Some individual 4–5 nm fibrils labelled with gold were observed in the material prepared from the 80,000 Da band. These results therefore establish that C. breviturrita produces a surface network of fibrils that are serologically related to the fimbriae of fungi, and suggest a previously unrecognized relationship between members of the Prymnesiophyceae, Chrysophyceae and fungal groups.

    Notes: Abstract Cells of Methanobacterium thermoautotrophicum were fixed with glutaraldehyde, sectioned and labeled with antibodies against the β subunit of component C (=methyl-CoM reductase) of methyl-CoM reductase system and with colloidal gold-labeled protein A. It was found that the gold particles were located predominantly in the vicinity of the cytoplasmic membrane, when the cells were grown under conditions where methyl-CoM reductase was not overproduced. This finding confirms the recent data obtained with Methanococcus voltae showing via the same immunocytochemical localization technique that in this organism methyl-CoM reductase is membrane associated.

    Topics: Biology
    Notes: Abstract We have investigated the in situ location of glutaconyl-CoA decarboxylase and 2-htdroxyglutaryl-CoA dehydratase in Acidaminococcus fermentans using the antibody-gold and protein A-gold techniques carried out as a post-embedding immunoelectron microscopic procedure. Polyclonal antisera were raised in rabbits against homogeneous fractions of the enzymes. Anaerobically grown cells of A. fermentans of the late exponential growth phase were fixed with 0.2% glutaraldehyde and 0.3% formaldehyde (final concentrations) in the growth medium. Dehydration of the cells was achieved with methanol. The cells were embedded in the low temperature embedding resin Lowicryl K4M. The markers indicative for antigenic sites of the two enzymes unequivocally demonstrate that the sodium pump glutaconyl-CoA decarboxylase is located at the cell periphery being a membrane-bound enzyme as expected whereas 2-hydroxyglutaryl-CoA dehydratase is a soluble cytoplasmic enzyme.

    Topics: Biology
    Notes: Abstract The subcellular localization of dihydroxyacetone synthase (DHAS) in the methylotrophic yeast Hansenula polymorpha was studied by various biochemical and immunocytochemical methods. After cell fractionation involving differential and sucrose gradient centrifugation of protoplast homogenates prepared from methanol-grown cells, DHAS cosedimented with the peroxisomal enzymes alcohol oxidase and catalase. Electron microscopy of this fraction showed that it contained mainly intact peroxisomes, whereas SDS-polyacrylamide gel electrophoresis revealed two major protein bands (75 and 78 kDa) which were identified as alcohol oxidase and DHAS, respectively. The localization of DHAS in peroxisomes was further established by immunocytochemistry. After immuno-gold staining carried out on ultrathin sections of methanol-grown H. polymorpha using DHAS-specific antibodies, labelling was confined to the peroxisomal matrix.
