Upar and EGFP expression analysis in homozygous B-Upar-EGFP mice by flow cytometry. Lung were collected from wild-type mice (+/+) and homozygous B-Upar-EGFP mice (Mut/Mut) , and analyzed by flow cytometry with anti-mouse Upar antibody. Mouse Upar was detectable in wild-type mice but not in B-Upar-EGFP mice. EGFP was exclusively detectable in B-Upar-EGFP mice but not in wild-type mice.
