Genetic Alterations
The development of the Anxa2 targeting vector started with selectable neomycin-resistance (Neor) and thymidine kinase (TK) genes within the plasmid pPNT. Two mouse cDNA probes specific for exons 2 and 3, containing the translation start site, and for exon 5 were used to isolate two fragments encoding exons 1–4 and exons 2–5. A 2.2-kb fragment located 5′ of exon 3 and a second 4-kb fragment located 3′ of exon 4 were isolated and then subcloned into the pPNT plasmid opposite to that of the Neor cassette. The integrity of the targeting vector was verified by sequencing and the construct was introduced into 129/SvJ ES cells by electroporation.
ES Cell Line
129Sv derived from 129S2/SvPas
Phenotype

These mice exhibit a normal outward phenotype.

Histologic analysis reveals fibrin accumulation in microvessels of all organs and tissues. Upon induced stress, it was observed defects in angiogenesis, socially in the oxygen-induced retinopathy model.

Donor's Note: "For angiogenesis experiments, 129X1/SvJ background mice are considered to be generally superior to the C57BL/6J background model. The resulting mice were subjected to the oxygen-induced retinopathy model of neoangiogenesis. Interestingly, the A2-deficient mice showed a severely blunted angiogenic response to relative hypoxia in this model."

Order Request Information

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Brian J. Kelly.

Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
