Strain specific B2M expression analysis in wild-type B-NDG mice and homozygous B-NDG hB2M/HLA-A11.1 mice plus by flow cytometry. Splenocytes, blood cells and bone marrow were collected from wild-type B-NDG mice and homozygous B-NDG hB2M/HLA-A11.1 mice plus, and analyzed by flow cytometry with species-specific anti-B2M antibody. Mouse B2M was detectable in wild-type mice but not in homozygous B-NDG hB2M/HLA-A11.1 mice plus. Human B2M was exclusively detectable in homozygous B-NDG hB2M/HLA-A11.1 mice plus but not in wild-type mice.

Strain specific HLA-A expression analysis in wild-type B-NDG mice and homozygous B-NDG hB2M/HLA-A11.1 mice plus by flow cytometry. Splenocytes, blood cells and bone marrow were collected from wild-type B-NDG mice and homozygous B-NDG hB2M/HLA-A11.1 mice plus, and analyzed by flow cytometry with species-specific anti-HLA-ABC antibody and anti-H2-K1/H2-D1 antibody. Mouse H2-K1/H2-D1 was detectable in wild-type mice but not in homozygous B-NDG hB2M/HLA-A11.1 mice plus. Human HLA-A was exclusively detectable in homozygous B-NDG hB2M/HLA-A11.1 mice plus but not in wild-type mice.
