Basic Information
-
Targeting strategy
-
Gene targeting strategy for B-hSRB1 mice. The exons 2-11 of mouse Scarb1 gene that encode the extracellular domain and partial transmembrane domain of were replaced by human SCARB1 exons 2-11 in B-hSRB1 mice.
-
mRNA expression analysis
-
Strain specific analysis of SRB1 gene expression in wild type (WT) mice and B-hSRB1 mice by RT-PCR. Mouse Srb1 mRNA was detectable in liver of WT mice (+/+). Human SRB1 mRNA was exclusively detectable in homozygous B-hSRB1 mice (H/H) but not in WT mice (+/+).
-
Protein expression analysis
-
Strain specific SRB1 expression analysis in homozygous B-hSRB1 mice by western blot. Liver was collected from wild type (WT) mice (+/+) and homozygous B-hSRB1 mice (H/H), and analyzed by western blot with species-specific anti-SRB1 antibody. SRB1 was detected in WT mice (+/+), homozygous B-hSRB1 mice (H/H), positive 293T cells and HepG2 cells when an anti-mSRB1 antibody recognizing the intracellular region of mouse SRB1 was used. Human SRB1 was exclusively detectable in homozygous B-hSRB1 mice (H/H).
