Studies on defined immunofluorescence in clinical immunopathology. II. Relationship of F/P ratios pf conjugates and staining properties in indirect immunofluorescence.
The effect of conjugate F/P ratios on titers of patient antibodies was evaluated with two model systems in IIF chessboard titrations, notably, antinuclear antibodies and the intercellular antibodies of pemphigus. The plateau titers of both antibodies and F/P conjugate ratios were analyzed and proved to have a high degree of linear relationship statistically. Single titrations of other tissue antibodies, including skin basement membrane antibodies of bullous pemphigoid, MTA, GPA, SMA, and ThA with the same group of conjugates yielded similar information. A quantitative relationship between the two parameters was established.
