摘要
In situ htbridization techniques for analyzing the murine DNA complement of mouse-hamster hybrid cells are described. Total genomic mouse DNA is labeled with biotin and hybridized without suppression to metaphase spreads from a mouse-hamster hybrid line containing the mouse fusion chromosome X12. Detection via fluorochrome-conjugated avidin reveals mouse chromosomal DNA with high sensitivity and permits the identification of both normal and aberrant murine chromosomes. Conversely, biotinylated total genomic DNA from a hybrid line can be used as a probe on normal mouse metaphase spreads if suppression techniques are employed, facilitating the analysis of mouse chromosomes present in the hybrid line. © 1990.
