Overview
Nomenclature: B6.Cg-Tg(TNF)#Xen
- Express the human tumor necrosis factor α (TNF-α) transgene, a cytokine implicated in the pathogenesis of human rheumatoid arthritis
- Exhibits severe chronic arthritis of the forepaws and hind paws, as shown by gross observation and histological analysis by approximately 20 weeks of age
- A useful model for studying inflammatory arthritis which does not require experimental manipulation
Orders by weight: Taconic cannot accept orders by weight for this model. Please note that shipments may contain animals with a larger weight variation.

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.
