The level of PLG in the plasma of these mice expressing the human plasminogen gene under the control of a mouse albumin promoter is approximately 16% of the level in control human plasma. Mice exhibit increased susceptibility to group A streptococci (GAS). Although enhanced green fluorescent protein (EGFP) is incorporated in the transgene, it is not expressed.

The level of PLG in the plasma of these mice expressing the human plasminogen gene under the control of a mouse albumin promoter is approximately 16% of the level in control human plasma. Mice exhibit increased susceptibility to group A streptococci (GAS). Although enhanced green fluorescent protein (EGFP) is incorporated in the transgene, it is not expressed.
A transgenic BAC was designed to place human plasminogen (PLG) and green fluorescent protein (EGFP) under the control of a mouse albumin promoter (Alb). A chimeric intron with optimized splice signals from the pCI expression vector was placed upstream of the PLG cDNA. An FRT site and PGK-Tn5-Neo cassette were placed downstream of EGFP. The whole region, with the exception of Alb sequences, was flanked by loxP sites oriented in opposite directions. The PLG BAC DNA was isolated and microinjected into fertilized oocytes. Pronuclear fertilized eggs obtained by mating (C57BL6/J x SJL/J)F1 or C57BL/6 female mice with (C57BL6/J x SJL/J) F1 male mice were used for injection. This line has been backcrossed to C57BL/6 fifteen of more times by the donating laboratory. EGFP expression is not seen.

Molecular Note | A cassette containing the human PLG cDNA from nucleotide -13 (A of ATG initiation codon as +1) to +2476 (including the entire coding sequence) was followed by the green fluorescent protein (EGFP) coding sequence, preceded by an internal ribosome entry site sequence (IRES) and a bacterial kanamycin-resistant gene (KAN). A chimeric intron with optimized splice signals from the pCI expression vector was placed upstream of the PLG cDNA. Homologous recombination between the transgene targeting construct and the murine Alb BAC was carried out in E. coli, replacing the murine Alb gene (from nucleotide -12 to exon 12) by the transgene cassette. EGFP expression is not detected. |

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project. We do not guarantee breeding performance and therefore suggest that investigators order more than one breeding pair to avoid delays in their research.
