Basic Information
-
Gene targeting strategy
-
The exons 1-3 of mouse Cd70 gene that encode the extracellular domain were replaced by human CD70 exons 1-3 in B-hCD70 mice.
-
mRNA expression analysis
-
Species-specific CD70 gene expression analysis in wild-type and humanized B-hCD70 mice by RT-PCR. Murine Cd70 mRNA was detected in thymocytes isolated from wild-type (+/+) mice, while human CD70 mRNA was detected in homozygous B-hCD70 (H/H) mice.
-
Protein expression analysis
-
Species-specific CD70 protein expression analysis in humanized B-hCD70 mice. Following LPS stimulation in vivo, bone marrow-derived dendritic cells were isolated from wild-type C57BL/6 (+/+) and homozygous B-hCD70 (H/H) mice and analyzed by flow cytometry using species-specific anti-CD70 antibodies. Murine CD70 protein was detected in wild-type mice, while human CD70 protein was detected in B-hCD70 mice.
