Overview

Nomenclature: FVB.129P2-Abcb1atm1Bor Abcb1btm1Bor Abcg2tm1Ahs N7

  • This triple targeted mutation model carries a disruption of the multi-drug resistance genes Abcb1a (encoding p-glycoprotein 3), Abcb1b (encoding p-glycoprotein 1) and Abcg2 (encoding BCRP/ABCG2)
  • Useful in studies of drug transport, oral bioavailability and multi-drug resistance
  • Triple homozygote mice may develop phototoxicity upon exposure to pheophorbide a, a chlorophyll metabolite, first expressed as ear lesions and can progress to mice becoming moribund. They may also display a novel type of protoporphyria characterized by elevated levels of protoporphrin IX. Both of these effects have been observed in single gene Bcrp homozygous knockouts.
  • See additional information on the roles of drug transporters Bcrp, Mdr1a and Mdr1b.
Orders by weight: Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.

Origin

The Mdr1a/b-Bcrp mouse was developed in the laboratory of Alfred Schinkel of the Netherlands Cancer Institute. The model was created through crossbreeding of the Mdr1a/b targeted mutation mouse and the Bcrp targeted mutation mouse in the Schinkel lab. The Mdr1a/b model was created through sequential targeting of the Abcb1a and Abcb1b genes in E14 ES cells. Resultant chimeras were backcrossed to FVB/N for seven generations (N7). The Bcrp model was created by targeting the Abcg2 gene in E14 embryonic stem cells derived from 129P2/OlaHsd mice and injecting the targeted cells into FVB blastocysts. Resultant chimeras were backcrossed to FVB/N for seven generations (N7). Taconic received stock of the triple targeted mutation line in April 2005. The colony is maintained by mating animals homozygous for all three mutations.

3998 males 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 3998 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.
