A panel of 11 monoclonal antibodies specific to alpha- or beta-tubulin subunits was used to study the location of tubulin molecules in cytoplasmic microtubules. Specificity of antibodies was confirmed by immunoblotting and immunofluorescence experiments on fixed cells. The limited proteolysis of tubulin with trypsin and chymotrypsin followed by(More)
A panel of nine antibodies, specific to antigenic determinants located on N- or C-terminal structural domains of alpha and beta subunits of animal tubulin, and antibodies against acetylated, tyrosinated and polyglutamylated tubulins were utilized for probing the Nicotiana tabacum microtubules. The specificity of antibodies was confirmed by immunoblotting on(More)
Distribution of post-translationally modified tubulins in cells of Nicotiana tabacum L. was analysed using a panel of specific antibodies. Polyglutamylated, tyrosinated, nontyrosinated, acetylated and Δ2-tubulin variants were detected on α-tubulin subunits; polyglutamylation was also found on β-tubulin subunits. Modified tubulins were detected by(More)
Using the monoclonal antibody MA-01, which recognizes a 210-kDa protein in cell-free extracts, spindle and cytoplasmic microtubules were visualized in budding yeast, Saccharomyces cerevisiae. In additional, a spot-like staining was found beneath the plasma membrane, revealing in part correlation with F-actin distribution. This pattern was common for cells(More)
The microtubule-associated protein MAP2 is essential for development of early neuronal morphology and maintenance of adult neuronal morphology. Several splice variants exist, MAP2a-d, with a lack of MAP2a in cat brain. MAP2 is widely used as a neuronal marker. In this study we compared five monoclonal antibodies (MAbs) against MAP2. They show differences in(More)
Expression of intermediate filament proteins was studied in human developing spinal cord using immunoperoxidase and double-label immunofluorescence methods with monoclonal antibodies to vimentin and glial fibrillary acidic protein (GFAP). Vimentin was found in the processes of radial glial cells in 6-week embryos, while GFAP appeared in vimentin-positive(More)
A monoclonal antibody, VI-01, to vimentin and desmin has been isolated from a fusion of mouse myeloma cells with immune spleen cells. The antibody appeared specific for vimentin of various species and smooth muscle desmin and did not recognize other intermediate filament proteins when cell lines and tissue sections were assayed in immunofluorescence and(More)
Individual beta-tubulin isoforms in developing mouse brain were characterized using immunoblotting, after preceding high-resolution isoelectric focusing, with monoclonal antibodies against different structural regions of beta-tubulin. Some of the antibodies reacted with a limited number of tubulin isoforms in all stages of brain development and in HeLa(More)
