These mice are useful when studying sulfotransferase conversion of cholesterol and other hormone substrates.

Targeted (Null/Knockout) | Sult2b1 | sulfotransferase family, cytosolic, 2B, member 1 |
In this strain, exons 4-8 of the sulfotransferase 2B1 (Sult2b1) gene were removed, abolishing gene expression. SULT2B1 is a sulfotransferase enzyme that transfer an SO3- group from the cofactor 3'-phosphoadenosine 5'-phosphate to the 3-hydroxyl position of cholesterol and other substrates such as some hormones and neurotransmitters. SULT2B1 is highly expressed in the skin of the mouse and at lower levels in the epididymis. Male and female homozygous Sult2b1 knockout mice are viable and fertile. They lack cholesterol sulfate in the dermis but otherwise appear to have normal lipid metabolism.
A targeting vector was designed to replace exons 4-8 of the sulfotransferase 2B1 (Sult2b1) gene with an ACN cassette. The ACN cassette, containing the neomycin resistance gene and Cre recombinase gene under the control of angiotensin-converting enzyme promoter, is flanked by loxP sites. Cre-mediated recombination during spermatogenesis removed the ACN cassette leaving one loxP site. The construct was electroporated into 129S6/SvEvTac derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6J blastocysts and the resulting chimeric males were bred to 129/SvJ females. The donating investigator reports that these mice were maintained on an isogenic 129/SvJ background (see SNP note below) and embryos were shipped to The Jackson Laboratory. Recovered mice were bred together to establish the colony.
A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. Three of the 27 markers throughout the genome suggested a C57BL/6 genetic contribution from an unknown source.

Chromosome | 7 |
Molecular Note | A targeting vector was designed to replace the seven coding exons the sulfotransferase 2B1 (Sult2b1) gene with a cassette containing the neomycin resistance gene and Cre recombinase gene under the control of angiotensin-converting enzyme promoter. This cassette was flanked by loxP sites. Cre-mediated recombination during spermatogenesis removed the inserted cassette leaving one loxP site. |

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We 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.
Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.
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.
