Overview
Nomenclature: B6.129S6-Rag2tm1Fwa N12
- Contains a disruption of the recombination activating gene 2 (Rag2)
- Homozygous mice exhibit total inability to initiate V(D)J rearrangement and fail to generate mature T or B lymphocytes. Otherwise, the Rag2 mouse has apparently normal hematopoiesis
- Useful for vaccine development, transplantation studies and hematopoiesis research. Through blastocyst complementation assays, can be useful in evaluating the function of specific genes in the differentiation of lymphocytes
- Carries the H2b haplotype
- Taconic recommends use of RAGN12 mice at the Murine Pathogen Free (MPF) for colitis studies involving adoptive T cell transfer. Use of RAGN12 mice at the Opportunist Free (OF) health standard should be considered based on facility-specific bioexclusion needs and other experimental considerations.
Recommended Controls
The recommended control for this model is C57BL/6NTac.
Origin
The Rag2 mouse was developed in the laboratory of Frederick W. Alt at Columbia University. The model was created by targeting the Rag2 gene in CCE ES cells and injecting the targeted cells into blastocysts. This line originated from model RAG2-M on a 129S6/SvEv background. The mice were backcrossed twelve generations (N12) to a C57BL/6NTac inbred background. Heterozygotes were intercrossed to generate homozygous targeted mutation mice. The line is maintained by incrossing homozygous mice.

RAGN12 males at 7+ weeks of age are packed as cagemates, without recombination of animals from different cages into a single Taconic Transit Cage (TTC). We recommend that customers do NOT recombine 7+ week old RAGN12 males from different Taconic Transit Cages into the same cage at or after unpacking.
Packing Practices
Taconic standard practice is to recombine animals of different home cages and/or ages from a single model and sex during packing, except in specific cases where Taconic's animal welfare policy prohibits recombination due to aggression or other concerns. When an order is fulfilled with animals from more than one week of birth, this standard practice results in animals from a range of birth weeks packed together in a single TTC. When an order is fulfilled with animals from genotyped models, this standard practice results in animals from different home cages packed together in a single TTC.
Customers who wish to keep animals from different weeks of birth separated should place orders with the special instruction "Divide and label by age." Note that this special request can result in increased costs for additional Taconic Transit Cages, dividers and/or freight charges.
Taconic discourages other types of custom packing requests as they can have a negative impact on animal welfare. Learn more.
