An enzyme-linked immunosorbent assay for the detection of hepatocyte plasma membrane antibodies. 1985

N R Swanson, and W N Bartholomaeus, and W D Reed, and R A Joske

An enzyme-linked immunosorbent assay (ELISA) using plates coated with hepatocyte plasma membranes (HPM) was developed for the measurement of antibodies directed at hepatocyte surface antigens. Precoating ELISA plates with poly-L-lysine (PLL) provided firm attachment for the adsorption of HPM. The use of HPM, in preference to whole hepatocytes, excludes pathologically irrelevant cytoplasmic antigens. In addition, there is no necessity for glutaraldehyde fixation which is commonly used in cellular assays to maintain cellular integrity and which may result in loss or alteration in antigenic specificities. The assay was used to study loss of tolerance to mouse HPM in mice immunized with rat HPM. Three mouse strains were immunized, each strain developed antibodies to rat HPM and autoantibodies to mouse HPM with autoantibody levels reaching a peak 6-10 weeks after commencement of immunization. The correlation between ELISA and indirect immunofluorescence for the measurement of HPM autoantibodies was 0.79 (P less than 0.001) within the serum titration range of 1:25 to 1:200. Antibody to control kidney plasma membrane (KPM) was also measured by ELISA, after elimination of endogenous alkaline phosphatase activity using levamisole. Immunization with rat HPM elicited organ-non-specific autoantibodies to KPM, but these were at lower levels than autoantibodies to HPM.

D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.
