FITC anti-IgM contains a goat polyclonal antibody raised against purified human IgM. The antibody is obtained through purification of the goat gamma globulin fraction, followed by reaction with fluorescein isothiocyanate. The excess fluorochrome is then removed by dialysis and the conjugated globulin is further fractionated on DEAE cellulose to remove over and under labeled protein.⁵ Immunofluorescent detection of IgM has been used to localize IgM deposits in biopsies from patients with membranous nephropathy⁶ and diabetes mellitus.⁷ IgM has also been detected via fluorescent immunochemistry in arteriolar walls in biopsies from hypertensive patients.⁸ Immunofluorescent detection of IgM in human dermal tissue and its involvement in dermal pathologies has been described elsewhere.⁴ FITC anti-IgM binds specifically with the heavy chain portions of human immunoglobulin M and its subclasses.

In general, immunohistochemical staining allows the visualization of antigens via the sequential application of a specific antibody (primary antibody) to the antigen, a secondary antibody (link antibody) to the primary antibody, an enzyme complex and a chromogenic substrate with interposed washing steps. The enzymatic activation of the chromogen results in a visible reaction product at the antigen site. For FITC direct labeled antibodies, the fluorochrome is linked to the primary antibody and therefore no secondary antibody or chromogenic detection step is required. The primary antibody binds specifically to the target antigen and can then be visualized. Results are interpreted using a fluorescent microscope with the appropriate filter set and aid in the differential diagnosis of pathophysiological processes, which may or may not be associated with a particular antigen.

FITC anti-IgM is optimally diluted for use with automated slide stainers. Each step in the staining protocol includes incubation for a precise time at a specific temperature. At the end of each incubation step, the sections are rinsed by the Ventana automated slide stainer to stop the reaction and remove unbound material that would hinder the desired reaction in subsequent steps. To minimize evaporation of the aqueous reagents from the specimen-containing slide a coverslip solution is applied in the slide stainer. For more detailed information on instrument operation, refer to the appropriate Ventana automated slide stainer operator's manual.", "Language": "en", "Country": "XG", "Code": "Principle" }, { "Name": "Product Purpose", "Value": "This antibody is intended for in vitro diagnostic (IVD) use.
