Isolation of rare transcripts by representational difference analysis
Representational difference analysis (RDA) is a powerful technique for cloning the differences between genomes, and has recently been adapted for cloning differentially expressed genes. RDA, like other PCR-based differential screening methods, is prone to the production of false positives. We have identified a major source of false positives in RDA of cDNA and have introduced improvements which...
متن کاملIsolation of osteosarcoma-associated amplified DNA sequences using representational difference analysis.
Comparative genomic hybridization analysis of a primary osteosarcoma and its metastasis revealed two regions of DNA amplification, one at 17p11.2-12 and one at 19q12-13. Subsequent representational difference analysis of the primary tumor resulted in the isolation of two distinct tumor-amplified DNA fragments originating from chromosome 19. A YAC clone corresponding to one of the two isolated D...
متن کاملDetection of homozygous deletions in tumors by hybridization of representational difference analysis (RDA) products to chromosome-specific YAC clone arrays.
Representational difference analysis (RDA), a subtractive hybridization method that enriches differences between complex genomes, can be used to isolate fragments deleted in tumor genomes. Usually, most of the clones obtained by this approach result from polymorphic fragments. Therefore, identification of homozygously deleted fragments, which can indicate the presence of tumor suppressor loci, ...
متن کاملIsolation of human transcripts expressed in hamster cells from YACs by cDNA representational difference analysis.
Gene isolation methods used during positional cloning rely on physical contigs consisting of bacterial artificial chromosomes, P1, or cosmid clones. However, in most instances, the initial framework for physical mapping consists of contigs of yeast artificial chromosome (YACs), large vectors that are suboptimal substrates for gene isolation. Here we report a strategy to identify gene sequences ...
متن کاملIsolation of differentially expressed genes by combining representational difference analysis (RDA) and cDNA library arrays.
The difference products (DP) of representational difference analyses (RDA) were used as hybridization probes on cDNA arrays. The effectivity of RDA products obtained with increasing driver/tester ratios (DP 1 = 100:1, DP 2 = 800:1 and DP 3 = 400,000:1) to isolate differentially expressed genes was compared with the effectivity of conventional differential hybridizations. Pacreatic cancer and co...
