Application of IGF2-specific identifier probe for cytogenetic study of somatic and sperm cells in horses.

This research paper examines the utilization of a locus specific identifier probe to accurately and selectively visualize the IGF2 gene in horse cells. This study is crucial in interpreting the results of interphase fluorescence in situ hybridization and sheds light on the varying number and location of FISH signals in somatic and sperm cells of horses.

Research Scope

• The research primarily focuses on utilizing a molecular technique known as Locus Specific Identifier probe (LSI) for the IGF2 gene in horse cells.
• The study aims to discern the structure of chromatin, which is a complex of DNA and protein in a cell’s nucleus.
• The research looks into the metaphase, interphase nuclei, and sperm cells for the application of the LSI.

Interphase Fluorescence in Situ Hybridization (I-FISH)

• Part of the study involves I-FISH, a cytogenetic technique that uses fluorescent probes that bind to only those parts of the chromosome with a high degree of sequence complementarity.
• I-FISH is used in the research to interpret results concerning the IGF2 gene.

Findings on FISH Signals

• The research also analyzes the variation in the number and location of the FISH signals in somatic and sperm cells of horse.
• The findings provide new insights into the varying frequency and localization of these signals, which are crucial for better understanding the genetic characteristics of horses in biological and veterinary studies.
