Overview

Nomenclature: FVB.129P2-Abcb1atm1Bor N7

  • Carries a disruption of multi-drug resistance genes Abcb1a (ATP-binding cassette, sub-family B (MDR/TAP), member 1A, a.k.a. Mdr1a) encoding p-glycoprotein 3
  • Mdr1a protein is expressed actively in the intestine and at the blood-brain and blood-testis barriers
  • p-glycoprotein 3 actively extrudes a wide range of drugs from cells and can confer multi-drug resistance to tumor cells
  • Lack the protective function of p-glycoprotein 3 and exhibits a functional deficiency in the blood-brain barrier
  • Useful in neurotoxicology, drug transport, chemotherapy, multi-drug resistance and oral bioavailability research
  • Susceptible to developing a severe, spontaneous intestinal inflammation phenotypically similiar to human inflammatory bowel disease (IBD)
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 mouse was developed in the laboratory of Alfred Schinkel of the Netherlands Cancer Institute. The model was created by targeting the Abcb1a gene in E14 ES cells. Resultant chimeras were backcrossed to FVB for seven (N7) generations. Taconic received stock in 1994 and derived the line by Caesarean transfer. The colony is maintained by incrossing homozygous mice.

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.
