Isolation of mini- and microsatellite loci from chromosome 19 library
- Molecular Genetics, Moscow (Russian Federation); and others
Mini- and microsatellite sequences are abundant in the human genome and are very useful as genetic markers. We report the isolation of a panel of clones containing marker sequences from chromosome 19. We screened 10,000 clones from the chromosome 19 cosmid library for the presence of di-(CA)n, tri-(TCC)n, (CAC)n microsatellites and M13-like minisatellite sequences. For this we have used synthetic oligonucleotides and polynucleotides, including micro- (CA, TCC, CAC) and minisatellite (M13 core) sequences. Preliminary results indicated that the chromosome 19 cosmid library contained both human and hamster clones. In order to identify human sequences from this library we have developed the technique of colony and blot hybridization with Alu-PCR, L1-PCR and B1-PCR probes. Dozens of clones have been selected, some of which were analyzed by conventional Southern blot analysis and non-radioactive in situ hybridization of chromosomes. Highly informative markers derived from these clones will be used for physical and genetic mapping of chromosome 19.
