Abstract Objective The objective was to investigate fixative solutions: 3.7% formaldehyde, 4% paraformaldehyde, 4% paraformaldehyde in the cytoskeletal buffer and 4% paraformaldehyde in PHEM buffer (containing PIPES, HEPES, EGTA and MgCl2), applicable for immunofluorescence assay. Results Herein we optimized this serological technique, testing four fixative solutions, for the sensitive detection of rickettsial antigens, and preservation of intracellular structures of the host cells, particularly filamentous actin. Rickettsial antigens were presented equally well both with formaldehyde and all paraformaldehyde-based fixations, but only protocol with 4% paraformaldehyde in PHEM buffer allowed accurate imaging of actin filaments, and simultaneously allows monitoring of rickettsiae using actin-based motility during infection inside the host cells.

Some standards for biocompatibility testing of biomaterials requires the determination of the cytoskeleton aspect of differentiated cells in contact with the material. It is usually determined by indirect immunofluorescence staining of cytoskeleton proteins and examination with a light microscope.This examination is difficult on non transparent material and the resolution is very poor. In order to study the interaction of osteoblast cytoskeleton with HA-macroporous ceramics, we grew chicken embryo osteoblasts on the material then we extracted cell membranes to expose the cytoskeleton proteins. They were then examined in SEM.

Abstract We describe the use of flow cytofluorometry to type lymphocytes for HLA-B27 antigens. We modified the cytotoxicity test of Terasaki and McClelland [Nature (London) 1964;204:998] for use with a flow cytofluorometer. In a second assay we used a commercially available monoclonal anti-HLA-B27 antibody and indirect immunofluorescence staining of cell surfaces. Although this antibody cross reacts with B7 and Bw22 antigens, the results for HLA-B27 and the cross-reacting antigens can be separated. Comparison of our results with those by a HLA-typing laboratory for 100 patients showed total agreement of the assigned typings.

An indirect immunofluorescence staining procedure was developed for detection of Brunchorstiapinea conidia, using antiserum to conidia and a commercially prepared fluorescein isothiocyanate protein A conjugate. The procedure detected B. pinea conidia from culture, pycnidia, and spore-trap collections. Although cross reactivity occurred with spores of Fusarium spp., Sirococcus sp., Phialophora sp., Gliocladium sp., Verticillium sp., and Gelatinosporium sp., these spores were easily distinguished from those of B. pinea by size, shape, septation, and degree of fluorescence. Fluorescent B. pinea like conidia were collected in spore traps located within and outside the New York State quarantine region. However, the identity of B. pinea like conidia could not be corroborated by other methods.
