the specificity of the antisera was proved by indirect immunofluorescence staining of the mitotic spindle , specific blocking of spindle staining by purified tubulin and not by other proteins , staining of 3t3 cytoplasmic microtubules , single line on immunoelectrophoresis , failure of control antisera to show any of these , and precipitation of antibody with all tubulin preparations and not with actin .
