Basic Information
Strain Name
C57BL/6-Gfaptm1(icre)/Bcgen
Stock Number
110144
Common Name
B-Gfap-iCre mice
Source/Investigator
Biocytogen Jiangsu Co., Ltd
Related Genes
Gfap (glial fibrillary acidic protein)
NCBI Gene ID
Background
C57BL/6
Appearance
Black
Genotype
Gfap iCre (wt/mut)
Development
A target vector was designed to insert iCre-WPRE-PA cassette into mouse endogenous genes 5 ‘UTR downstream of GFAP. The targeting vector was electroporated into C57BL/6-derived embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts and resulted in chimeric mice. These mice were maintained on a C57BL/6 background.
Application
This Gfap-iCre model is an efficient tool to study various gene functions when crossed with mice with different loxP site-flanked genes of interest, especially in studies of astrocytes cells related signaling.
