Some fluorescent counterstains for neuroanatomical studies.
Methods for counterstaining neural tissue that contains fluorescent markers have been developed. Acridine orange is useful for localizing cells that are retrogradely labelled with the fluorescent tracers true blue, bisbenzimide, and nuclear yellow because at low concentrations it yields a green Nissl stain when excited with blue, but not with ultraviolet, light; since the tracers fluoresce only...
متن کاملImmunofluorescence techniques.
anTiBOdies An antibody is a protein complex produced by B cells that initiates an immune response against a target antigen. The basic organization of an antibody includes two functional domains that, together, resemble the letter Y (Figure 1, left). The Fab (fragment having the antigen binding site) domain makes up the arms of the Y, and at the end of each arm is a variable region responsible f...
متن کاملDirect and indirect immunofluorescence.
Immunofluorescence is a valuable auxiliary diagnostic tool for autoimmune bullous diseases and inflammatory disorders, since their clinical and histopathologic findings may be inconclusive. It is a feasible laboratory method that requires experienced technicians and detects in situ and circulating immune deposits that may be involved in the pathogenesis of such skin diseases.
متن کاملMulticolor Immunofluorescence Imaging
Protocols for immunolabeling vary widely due to experimental goals. Interactions that contribute to antibody binding include hydrogen bonds, ionic bonds, hydrophobic interactions and van der Waals forces. The strength of each of these interactions is weak compared to a covalent bond. Consequently, a large number of noncovalent interactions are required to stabilize antibody binding to an antige...
متن کاملImmunofluorescence in dermatology.
Direct immunofluorescence (DIF) and indirect immunofluorescence (IIF) tests on skin biopsy are being done mostly in academic teaching hospitals. These tests provide a useful diagnostic aid to dermatologists. Immunohistology and serology can, in conjunction with histology, provide considerable help in delineation and diagnosis of various skin disorders as well as systemic diseases with skin invo...
