Abstract:
The development of dense genetic maps of mammalian chromosomes is facilitated when chromosome-specific libraries are used as a source of genetic markers. To saturate the genetic maps of mouse chromosomes 4 and 6, we have made use of fluorescent-activated chromosome sorting to purify a 4:6 Robertsonian chromosome from a cell line harboring the Rb(4:6)2Bnr translocation. After staining with chromomycin A3 and Hoechst 33528, this chromosome was separated from the other mouse chromosomes. DNA was isolated from the fraction containing the Robertsonian chromosome and subcloned into the insertion vector lambda gt10, generating a library with 4.6 x 10(5) independent phage. A total of 19 single-copy sequences were used to type the progeny of a C57BL/6J x Mus spretus backcross that had previously been typed for loci on chromosomes 4 and 6. Approximately 70% of the clones in the library mapped to either chromosome 4 or 6 as assessed by genetic mapping and by use of a somatic cell hybrid panel. Simple sequence repeats have also been isolated from this library. Further characterization of these microsatellites should accelerate efforts to map mouse chromosomes 4 and 6 using PCR. In addition, flow sorting of Robertsonian chromosomes suggests a general approach for making chromosome-specific libraries in mouse.
