Ins2{Apple.LCA} mouse ESC line A mouse ESC line in which the targeted gene, Insulin 2 (NCBI Gene ID: 20671), has been modified (allele type: Cassette Acceptor) to (MGI ID: Ins2{(apple.LCA)}). This ES cell line was made by gene targeting and designed to express a H2B-Apple fusion protein (nuclear red fluorescent protein) from the Ins2 promoter. The FP coding sequence is downsteam of the Ins2 start codon (replacing exon 2 of Ins2) and is flanked by Lox66/Lox2272 sites to allow for future manipulations of the flanked region by RMCE.
