Quantitative analysis of the A, B and H isoantigens in single transitional carcinoma cells.
To obtain objective data on deletion of the ABH isoantigens in bladder carcinoma, microfluorometry was used. Slides were scanned in phase contrast to lessen fading of the immuno- or lectin-fluorescence stained cells. The fluorescence intensity was measured in relation to an external uranyl standard. Staining was most intense in the peripheral and cytoplasmic parts of the cells. The intra specimen fluorescence intensity varied as 1 to 10. In nondeleted cell populations fluorescence intensity means ranged from 1025 to 12,550 and in deleted populations from 304 to 510. Microfluorometry accurately separates deleted cell populations from those with a normal ABH antigen content.
