摘要: This study was carried out to develop a rapid and simultaneous detection system of chromosome Y- 1-bearing porcine spermatozoa by fluorescence in situ hybridization (FISH). Chromosome 1-specific DNA probes were produced polymerase chain reaction with digoxigenin (Dig)- or biotin-dUTP. The probe mixture labeled Y-chromosome applied the preparation, immediately denatured at 75°C for 8 min, hybridized 5 min 37°C overall FISH steps done within few hours. When double Dig-labeled Y-specific biotin-labeled sperm nuclei pretreated dithiothreitol, average 50.9% had Dig-signal, 99.2% biotin-signal 0.3% showed no signal. putative rate Y-bearing ranged from 49.8% 52.8% among boars 51.0%. results indicated that PCR made possible more accurate assessment spermatozoa. © 1996 Wiley-Liss, Inc.
