| molecularNote | A vector, which contains (5' to 3') a splice acceptor, floxed neo/stop cassette and sequence encoding mutated nuclear localized lacZ with 289 bp intragenic duplication after the ATG such that a shift in codon phase introduces a premature STOP codon was inserted into the locus via homologous recombination. The parental Gt(ROSA)26Sortm2Etz was crossed to cre deleter to remove the floxed neo/stop cassette. The duplication in the lacZ sequence truncated b-galactosidase molecule making the lacZ allele is inactive, except in small fraction of cells undergone infrequent spontaneous random intragenic homologous recombination restoring the functional lacZ sequence. |
