Description
Mice that are homozygous for the targeted mutation are viable, fertile, and normal in size but exhibit phagocytic immunodeficiency. No endogenous gene product (mRNA or protein) was detected by Northern blot analysis, RT-PCR or Western blot analysis. The Rac proteins are a subclass of the Rho family of GTPases, and are involved in actin cytoskeletal organization in cell movement, cell proliferation, kinase signaling pathways, and in superoxide production in phagocytic cells. Neutrophils and mast cells derived from homozygous mice display abnormal actin-based functions: cytoskeleton remodeling ability, adhesion, migration, degranulation, and phagocytosis. Diminished superoxide production in response to some agonists, and reduced total number of leukocytes and neutrophils in peritoneal exudate is observed. As result of functional deficiencies in neutrophil and mast cell populations, these mutant mice are more vulnerable to invasive infection. Slowed growth of mast cells, accompanying reduction in mast cell number and a significant decrease in growth factor-dependent survival was found to be due to increased cell apoptosis. These mutant mice may be useful in studies of phagocytic immunodeficiency, cellular inflammatory responses, hematopoietic cell regulation, and B cell development and signaling.

Development
A targeting vector containing neomycin resistance and herpes simplex virus thymidine kinase genes was used to disrupt exon 1 of the Rac2 gene. The construct was electroporated into 129S6/SvEv derived CCE.1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice.

Supply Notes

Cryorecovery - Standard. We will fulfill your order by providing at least two pair of mice, at least one animal of each pair carrying the mutation of interest. The total number of animals provided, their gender and genotype will vary. Please inquire if larger numbers of animals with specific genotype and genders are needed. Animals typically ship between 13 and 16 weeks from the date of your order. If a second cryorecovery is needed in order to provide the minimum number of animals, animals will ship within 25 weeks. IMPORTANT NOTE: The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.

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.

"PRODUCTS" means biological materials supplied by JACKSON, and their derivatives. "RECIPIENT" means each recipient of MICE, PRODUCTS, or services provided by JACKSON including each institution, its employees and other researchers under its control. MICE or PRODUCTS shall not be: (i) used for any purpose other than the internal research, (ii) sold or otherwise provided to any third party for any use, or (iii) provided to any agent or other third party to provide breeding or other services. Acceptance of MICE or PRODUCTS from JACKSON shall be deemed as agreement by RECIPIENT to these conditions, and departure from these conditions requires JACKSON's prior written authorization.

In case of dissatisfaction for a valid reason and claimed in writing by a purchaser within ninety (90) days of receipt of mice, products or services, JACKSON will, at its option, provide credit or replacement for the mice or product received or the services provided.

No Liability

In no event shall JACKSON, its trustees, directors, officers, employees, and affiliates be liable for any causes of action or damages, including any direct, indirect, special, or consequential damages, arising out of the provision of MICE, PRODUCTS or services, including economic damage or injury to property and lost profits, and including any damage arising from acts or negligence on the part of JACKSON, its agents or employees. In purchasing or receiving MICE, PRODUCTS or services from JACKSON, purchaser or recipient, or any party claiming by or through them, expressly releases and discharges JACKSON from all such causes of action or damages, and further agrees to defend and indemnify JACKSON from any costs or damages arising out of any third party claims.

MICE and PRODUCTS are to be used in a safe manner and in accordance with all applicable governmental rules and regulations.

The foregoing represents the General Terms and Conditions applicable to JACKSON’s MICE, PRODUCTS or services. In addition, special terms and conditions of sale of certain MICE, PRODUCTS or services may be set forth separately in JACKSON web pages, catalogs, price lists, contracts, and/or other documents, and these special terms and conditions shall also govern the sale of these MICE, PRODUCTS and services by JACKSON, and by its licensees and distributors.

Acceptance of delivery of MICE, PRODUCTS or services shall be deemed agreement to these terms and conditions. No purchase order or other document transmitted by purchaser or recipient that may modify the terms and conditions hereof, shall be in any way binding on JACKSON, and instead the terms and conditions set forth herein, including any special terms and conditions set forth separately, shall govern the sale of MICE, PRODUCTS or services by JACKSON.
