Pdx1{H2B.Neptune} mouse ESC line A mouse ESC line in which part or all of the targeted gene, pancreatic and duodenal homeobox 1 (NCBI Gene ID: 18609) is replaced to create Pdx1{H2B.Neptune} using the Loxed Cassette Acceptor allele Pdx1{tm1(LCA)}). In this line, the first exon of Pdx1 is replaced with coding sequence for mNeptune (a far red fluorescent protein) using RMCE in the Pdx1 LCA allele. Generation of a Pdx-promoter driven mNeptune fluorescent allele will enable the isolation of pancreatic lineage cells by FACS and broaden the possibilities for combinatorial sorting with other fluorescent alleles.
