Strain specific analysis of TEK gene expression in wild-type mice and B-hTEK mice by RT-PCR. Mouse Tek mRNA was detectable in the lung of wild-type mice (+/+). Human TEK mRNA was detectable only in homozygous B-hTEK but not in wild-type mice.

Strain specific TEK expression analysis in homozygous B-hTEK mice by flow cytometry.Lung was collected from wild-type mice (+/+) and homozygous B-hTEK mice (H/H), and analyzed by flow cytometry with anti-TEK antibody. Mouse TEK was only detectable in wild-type mice. Human TEK was detectable in both homozygous B-hTEK mice and wild-type mice because of the cross-action antibody.
