Genetic Alterations
Transgenic (Tg) 2- 12 H mice were generated using the rearranged V(D)J segment from the hybridoma 2-12H. This variable immunoglobulin gene segment was cloned upstream of the Igha Cu gene. Purified DNA insert was injected into (C57BL/6 x SJL)F1 blastocysts and then implanted into pseudopregnant mice. Two Tg founders were obtained and further backcrossed to C57BL/6 or C.B17? mice for eight or more generations. The mixed origin line was since been backcrossed to C57BL/6 thirteen generations. Transmission of the transgene was verified by polymerase chain reaction analysis of tail DNA using an ogligonucleotide identical to a sequence 470bp 5' of the 2- 12 Vh exon (5'-CAGACTAAGGCCAAATATCAACTGAGAGA-3') and an oligonucleotide complementary to a sequence 3' og Jh4 (5'-CAGGCTCCACCAGACCTCTCTAGA-3').

Transgenic Vk8 mice were generated by microinjection of cloned functionally rearranged Vk8 L chain gene DNA into (CL57BL/6 x SJL) F1 x F1 zygotes and transferred into pseudopregnant ICR/Halcr females. Inbreed lines were stablished by backcrossing founder mice to BALB/c mice for six or more generations. The BALB/cbackground have been backcrossed to C57BL/6 thirteen generations. Mice containing the transgene were identified by polymerase chain reaction analysis of tail DNA using an oligonucleotide complementary to the Vk8 leader (5'-GGTACCTGTGGGACATTGTG- 3') and an oligonucleotide specific to the Vk8/Jk5 junction (5'- AGCACCGAACGTGAGAGG-3').

Mice containing the 2-12H transgene and mice containing the Vk8 transgene were bred to produce mice with both transgenes, referred to as 2-12h/Vk8 Tg mice.

    Units Notes
    031069-UNC-RESUS Litter recovered from cryo-archive $2,914.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    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.
