title: Cytogenetic methodologies for gene mapping and comparative analyses in mammalian cell culture systems.
abstract: Presented here are the detailed methods employed in our laboratory for gene mapping and cytogenetic analyses in human beings, in the domestic cat, and in other mammalian species. Induced in the procedures are: 1) establishment of primary fibroblast and lymphoid cell cultures; 2) heterologous cell fusion for production of rapidly proliferating cell hybrids; 3) cellular transformation of primary fibroblasts using an oncogenic retrovirus; 4) cell synchronization for high-resolution banding of promethaphase chromosomes; 5) chromosome-banding procedures, including G-banding, alkaline G-11, and Q-banding; and 6) in situ hybridization of radiolabeled molecular clones to metaphase chromosomes for regional gene localization.
