Simultaneous staining of nuclear DNA and blood group cell surface antigens on cells from bladder irrigation fluid.

: Simultaneous staining of nuclear DNA and blood group cell-surface antigens is proposed as a means of studying the prognosis of superficial bladder cancer. The quality of the results obtained on urothelial cells from bladder irrigation fluid, as shown by fluorescence microscopy, suggests that this staining technique may be suitable for flow cytometry.
