An improved shotgun antisense method for mutagenesis and gene identification. Academic Article uri icon

abstract

  • Shotgun expression of antisense cDNA, where each transformed cell expresses a different antisense cDNA, has been used for mutagenesis and gene identification in Dictyostelium discoideum. However, the method has two limitations. First, there were too few clones in the shotgun antisense cDNA library to have an antisense cDNA for every gene in the genome. Second, the unequal transcription level of genes resulted in many antisense cDNAs in the library for some genes but relatively few antisense cDNAs for other genes. Here we report an improved method for generating a larger antisense cDNA library with a reduced percentage of cDNA clones from highly prevalent mRNAs and demonstrate its utility by screening for signal transduction pathway components in D. discoideum.
