Pdx1{LCA} mouse ESC line A mouse ESC line in which the targeted gene, pancreatic and duodenal homeobox 1 (NCBI Gene ID: 18609), has been modified (allele type: Cassette Acceptor) to targeted mutation 1 (MGI ID: Pdx1{tm1(LCA)}). This mouse ES cell line contains a loxed cassette acceptor (LCA) allele that may be utilized for the exchange of DNAs of interest into the Pdx1 gene locus by recombinase mediated cassette exchange (RMCE). An 8.62 kb region of the gene was replaced by tandemly oriented Lox66 and Lox2272 sites flanking both positive (puromycin) and negative (HSV-TK)selectable markers. Person: Mark A.
