Abstract: A method for the determination of anti-treponemal antibody in a test sample comprises contacting a substrate for the anti-treponemal antibody with sample; treating the contacted substrate with labeled antihuman Ig antibody selected from (a) a mixture comprising enzyme labeled antihuman Ig antibody and fluorescent labeled antihuman Ig antibody, (b) antihuman Ig antibody labeled with an enzyme and a fluorescent label, and (c) fluorescent labeled antihuman Ig antibody to which enzyme labeled antibody against the animal species from which the antibody used in the fluorescent labeled antibody was derived is added subsequently, and (d) enzyme labeled antihuman Ig antibody to which fluorescent labeled antibody against the animal species from which the antibody used in the enzyme labeled antibody was derived is subsequently added; determining the enzyme activity of the treated substrate; and determining the immunofluorescent patterns in substrates exhibiting enzyme activity.

Abstract: A method for the determination of anti-Epstein-Barr Virus antibodies in a test sample comprises contacting a substrate for the anti-Epstein-Barr Virus antibodies with sample; treating the contacted substrate with labeled antihuman Ig antibody selected from (a) a mixture comprising enzyme labeled antihuman Ig antibody and fluorescent labeled antihuman Ig antibody, (b) antihuman Ig antibodies labeled with an enzyme and a fluorescent label, (c) fluorescent labeled antihuman Ig antibody to which enzyme labeled antibody against the animal species from which the antibody used in the fluorescent labeled antibody was derived is subsequently added, and (d) enzyme labeled antihuman Ig antibody to which fluorescent labeled antibody against the animal species from which the antibody used in the enzyme labeled antibody was derived is subsequently added; determining the enzyme activity of the treated substrate; and determining the immunofluorescent patterns in substrates exhibiting enzyme activity.

Abstract: A method for the determination of autoantibody in a test sample comprises contacting a substrate for the autoantibody with sample; treating the contacted substrate with labeled antihuman antibody selected from (1) a mixture comprising enzyme labeled antihuman antibody and fluorescent labeled antihuman antibody, and (2) antihuman antibody labeled with an enzyme and a fluorescent label; determining the enzyme activity of the treated substrate; and determining the immunofluorescent patterns in substrates exhibiting enzyme activity. The method is useful for the rapid screening and characterization of autoantibodies.
