FIG. 2.
(A to F) Expression of TR2 represented by β-Gal activity in TR2+/− heterozygous mice. Testes from postnatal mice of different ages were processed through whole-mount X-Gal staining, embedded in paraffin, sectioned, and counterstained with H&E. Magnification, ×100. Panels A to F show samples from mice aged 1, 2, 3, 4, 5, and 6 weeks, respectively. Positive staining is indicated by arrows. (G) Northern blot analysis of total RNA from testis tissue of mice at 1, 2, 3, 4, 5, and 6 weeks of age. The same membrane was sequentially hybridized with 32P-labeled TR2 and β-actin probes.
