| molecularNote | The human placental alkaline phosphatase (ALPP; PLAP) coding region was engineered to contain a single intron with a loxP site. Another loxP site in inverted orientation was placed 3' of the ALPP coding region. A single round of Cre-mediated recombination in E. coli resulted in the inversion of the 3' half of the coding region, thereby disrupting the ALPP open reading frame. This construct, referred to as "AP inversion" or "AP inv", was knocked into the ubiquitously-expressed Gt(ROSA)26Sor locus by homologous recombination. This allele has an inverted human placental alkaline phosphatase (ALPP; PLAP) coding segment flanked by oppositely-oriented loxP sites integrated in the Gt(ROSA)26Sor gene. Cre excision of the floxed segment flips rather than excises the ALPP inversion and reinstates a transcriptionally active form of the gene. This reporter can be activated by tissue-specific cre recombinase in any cell in the body at any time in development. |
