A. Western blot of whole urinary bladder (40 mg) for P2X2 receptor expression in postnatal (P0-P36) and adult (A) rats. Erk staining was used as a loading control. B. Preabsorption of P2X2 antibody with immunogen (1 mg ml−1) eliminated the band at 90kD. C. Histogram of relative P2X2 band density in all groups examined normalized to erk-1 staining. P2X2 receptor expression in urinary bladder demonstrated an age-dependent (R2 = 0.96, p ≤ 0.005) decrease in expression. P2X2 receptor expression in urinary bladder from P0-P14 is significantly greater compared to adult expression. *, p ≤ 0.005.
