NIGMS human/rodent somatic cell hybrid mapping panels 1 and 2.

ABSTRACT

The NIGMS Human Genetic Mutant Cell Repository is currently distributing two well-characterized human/rodent somatic cell hybrid mapping panels. Mapping Panel 1 consists of DNA isolated from 18 hybrid cell cultures retaining from 1 to 19 human chromosomes. Mapping Panel 2 contains DNA from hybrids retaining 1 or 2 human chromosomes. All but 2 of the hybrids retain a single intact human chromosome. Mapping Panel 2 is also available as cell cultures. These resources should prove valuable to the Human Genome Project initiative. This article describes the sources of the hybrid cell cultures and the procedures utilized to prepare and characterize the panels.
