Rapid and specific identification of chromosomes can be attained in situ using the PRimed IN Situ (PRINS) labelling technique. We have adapted this technique to mature human sperm in combination with a protocol for simultaneous decondensation and denaturation of sperm nuclei. This strategy allowed u
## Abstract Direct in situ labeling of human spermatozoa was performed using the PRINS method. This technique is based on annealing of specific oligonucleotide primers, and subsequent primer extension by a __Taq__ DNA polymerase. The reaction was carried out on a programmable temperature cycler, an
Nonradioactive in situ hybridization with an ctsatellite DNA probe specific for chromosome 18 was performed on human interphase sperm nuclei to detect the frequency of sperm cells disomic for chromosome 18. A total of 16127 sperm heads from eight healthy donors, aged 23-57 years, was investigated, a
Primed in situ labeling (PRINS) is a relatively new technology with wide-ranging applications in clinical cytogenetics. Using PRINS, we have identified the chromosomal origin of marker chromosomes in three patients. In the first patient with primary amenorrhea, we were able to confirm the marker chr
