Basic Information

Strain Name
C57BL/6-Ncr1tm1(iCre)Bcgen/Bcgen
Stock Number
110127
Common Name
B-Nkp46-iCre mice
Source/Investigator
Bcgen (Beijing Biocytogen Co., Ltd)
Related Genes
Ncr1 (natural cytotoxicity triggering receptor 1); Ly94; NKp46
Background
C57BL/6
Appearance
Black
Genotypes
Ncr1 (wt/mut)
Development
In this strain, Cre recombinase expression is under the control of Ncr1 promoter. When crossed with a strain containing a loxP site-flanked sequence of interest, Cre-mediated recombination results in deletion of the flanked sequence in Ncr1 expressing cells.
NCBI Gene ID

Targeting Strategy

An IRES-iCre sequence cassette was placed between the coding sequence of exon 7 and 3’UTR of the Nkp46 gene using C57BL/6 embryonic stem cells. Neo cassette flanked by frt sites was inserted at least 300bp downstream of 3’UTR. This strain was maintained on a C57BL/6 genetic background.
