C.129S4(B6)-Col3a1^tm1Jae/J

Stock number: 002907
Product name: Col3a1-
Research areas: Cardiovascular Research, Developmental Biology Research

Detailed description

Mice homozygous for the Col3a1^tm1Jae targeted mutation exhibit a shorter life span with approximately 10% of homozygous mutant mice surviving to adulthood. The major cause of death of is rupture of the major blood vessels.

Development

The first two exons of the Col3a1 were replaced by a vector containing a neo resistance gene. The construct was electroporated into 129S4/SvJae-derived J1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6. These mice were backcrossed to BALB/c for at least 5 generations.

Allele

Symbol: Col3a1^tm1Jae
Name: targeted mutation 1, Rudolf Jaenisch
MGI accession ID: MGI:1857431
Generation method: Targeted
Attributes: Null/Knockout
Marker symbol: Col3a1
Marker name: collagen, type III, alpha 1
Chromosome: 1
Strain of origin: 129S4/SvJae
Molecular note: A neomycin selection cassette replaced a genomic fragment containing the promoter region and first exon of the gene. Protein analysis of isolated tail and skin collagens from homozygous mice demonstrated that no stable protein was produced from this allele.
