Strain specific CD3E expression analysis in homozygous B-hCD3E/hCD38 mice by flow cytometry. Splenocytes were collected from wild type (WT) mice (+/+) and homozygous B-hCD3E/hCD38 mice (H/H;H/H), and analyzed by flow cytometry with species-specific anti-CD3ε antibody. Mouse CD3E was detectable in WT mice (+/+). Human CD3E was exclusively detectable in homozygous B-hCD3E/hCD38 mice (H/H;H/H) but not in WT mice (+/+).
