Stock number: 004364
Product name: TCRaKO bKO
Research areas: Hematological Research, Immunology, Inflammation and Autoimmunity Research, Research Tools

Description

These Tcra and Tcrb double knock-out mice may be useful in studies related to production of the immunoglobulin (Ig)E class of antibodies in the pathogenesis of allergies.

Detailed description

Mice that are homozygous for the targeted mutation are viable and fertile. Mutant mice display early stage arrest of alpha beta thymocyte differentiation. Mice may develop inflammatory bowel disease.
