These fertilin β (Adam2) mutant mice may be useful in reproductive biology studies; specifically to determine the role of ADAM (A Disintegrin And Metalloprotease) family proteins in sperm-egg interactions, fertilization, and spermatogenesis. These mice may also be useful in conjunction with other ADAM family mutant mice, including the cyritestin (Adam3)-deficient strain (see Stock No. 008043).

Description

The genotypes of the animals provided may not reflect those discussed in the strain description or the mating scheme utilized by The Jackson Laboratory prior to cryopreservation. Please inquire for possible genotypes for this specific strain.

Description
Mice homozygous for this fertilin β (Adam2) mutant allele are viable with no gross phenotypic abnormalities reported. Both precursor and processed fertilin β proteins were absent from spermatogenic cells and mature sperm isolated from homozygous males. While homozygous females are fertile with normal egg activation, homozygous males exhibit sperm deficiencies in sperm-egg membrane adhesion, sperm-egg fusion, migration from the uterus into the oviduct, and binding to the egg zona pellucida, rendering them infertile. These fertilin β (Adam2) mutant mice may be useful in reproductive biology studies; specifically to determine the role of ADAM (A Disintegrin And Metalloprotease) family proteins in sperm-egg interactions, fertilization, and spermatogenesis. These mice may also be useful in conjunction with other ADAM family mutant mice, including the cyritestin (Adam3)-deficient strain (see Stock No. 008043).

Development
A targeting vector was designed to replace exon 14 of the targeted gene with a PGK-neo cassette. The construct was electroporated into 129P2/OlaHsd-derived BK4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and chimeric males were bred with C57BL/6N to produce heterozygous mutant mice. The donating investigators maintained these mice by breeding homozygous females to heterozygous males for many generations prior to arrival at The Jackson Laboratory. Upon arrival, mice may have been bred to C57BL/6NJ (Stock No. 005304) for at least one generation to establish the colony.

The Jackson Laboratory's Genotype Promise

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.
