Fluorescence in situ hybridization (FISH) Protocol in Human Sperm
Aneuploidies are the most frequent chromosomal abnormalities in humans. Most of these abnormalities result from meiotic errors during the gametogenic process in the parents. In human males, these errors can lead to the production of spermatozoa with numerical chromosome abnormalities which represent an increased risk of transmitting these anomalies to the offspring. For this reason, the techniq...
متن کاملSperm Identification in Maize by Fluorescence in Situ Hybridization.
The two sperm cells of common origin within the pollen tube of flowering plants are each involved in a fertilization event. It has long been recognized that preferential fusion of one sperm with the egg can occur in B chromosome-containing lines of maize. If the second pollen mitosis begins with a single B chromosome, nondisjunction will result in one sperm possessing two B chromosomes and the ...
متن کاملSexing of Dog Sperm by Fluorescence In Situ Hybridization
Effective preselection of sex has been accomplished in several species of livestock and also in humans using the flow cytometric sperm sorting method. A guaranteed high sorting accuracy is a key prerequisite for the widespread use of sperm sexing. The standard validation method is flow cytometric remeasurement of the DNA content of the sexed sperm. Since this method relies on the same instrumen...
متن کاملAccuracy Assessment of Interphase Fluorescence In-Situ Hybridization on Uncultured Amniotic Fluid Cells
a:4:{s:10:"Background";s:431:"Parental anxiety while waiting for the results of amniocentesis has been investigated by many authors. It seems that the implementation of faster techniques such as fluorescence in-situ hybridization (FISH) will have some benefits in reducing this anxiety. Besides the patients' attitudes to choosing this method, gynecologists who are the persons responsible for tre...
متن کاملChromosome studies in human sperm nuclei using fluorescence in-situ hybridization (FISH).
The use of chromosome specific DNA probes labelled with fluorochromes and especially the combination of several probes has been used to indirectly study the chromosome constitution of decondensed sperm nuclei by fluorescence in-situ hybridization (FISH), and has allowed to include this test in the protocol of study of infertile males. Still, if the test is to be valid, several strict conditions...
