Immunofluorescent staining of Drosophila larval brain tissue.
INTRODUCTION The Drosophila larval brain is a well-established model for investigating the role of stem cells in development. Neuroblasts (neural stem cells) must be competent to generate many thousands of differentiated neurons through asymmetric divisions during normal development. Studies in fly neuroblasts have been instrumental in identifying how the establishment and maintenance of cell p...
متن کاملImmunofluorescent staining of Treponema pallidum and Treponema pertenue in tissues fixed by formalin and embedded in paraffin wax.
The main problems in identifying Treponema pallidum in tissues are optical definition contrast, and specificity. In general, fluorochrome staining provides optical definition and contrast superior to that obtained by ordinary tinctorial staining, and in theory improved resolution. Specificity is lacking however, as with other stains. In contrast, immunofluorescence should combine the optical ad...
متن کاملOptimized Protocol of Methanol Treatment for Immunofluorescent Staining in Fixed Brain Slices
We optimized methanol treatment in paraformaldehyde-fixed slices for immunofluorescent staining of ependymal basal bodies in brain ventricles. As 100% methanol induced severe deformations to the slices (including rolling and folding over), we tried to decrease methanol concentration. We found that 33.3% to 75% methanol could result in ideal immunostaining of basal bodies without inducing obviou...
متن کاملApplication of immunoperoxidase techniques to formalin-fixed brain tissue for the diagnosis of rabies in southern Africa.
Two immunoperoxidase techniques, viz. avidin-biotin complex (ABC) and peroxidase-anti-peroxidase (PAP) procedures, were applied to paraffin-wax-embedded brain-tissue sections, from brains which had been fixed in 10% formalin, to demonstrate the presence of rabies-virus antigen by light microscopy. These techniques positively identified both "viverrid" and "canid" rabies-virus antigen in tissues...
متن کاملEffects of prolonged water washing of tissue samples fixed in formalin on histological staining
The effects of prolonged water washing after fixation for 48 h in 10% (v/v) phosphate-buffered neutral formalin on the quality of representative histological staining methods were evaluated using samples of liver, kidney, spleen and thymus collected from three male Crl:CD(SD)(IGS) rats and one male beagle dog. Because door-to-door courier services in Japan prohibit handling formalin, our goal w...
