title: Counterimmunoelectrophoresis for identification of equine urine.
abstract: Counterimmunoelectrophoresis was evaluated as a method to distinguish urine of human origin from that of equine origin. The procedure used anti-equine serum and anti-human serum antibodies that had been solid-phase absorbed to eliminate species cross-reactivity. Counterimmunoelectrophoresis reliably detected contamination of equine urine by human urine to a level of 10% with a minimum sensitivity to about 2% contamination. Compared with double diffusion, counterimmunoelectrophoresis was approximately 10 to 15 times more sensitive in the detection of urine proteins.
