Fig. 4From: Sex-specific differences in organic anion transporting polypeptide 1a4 (Oatp1a4) functional expression at the blood–brain barrier in Sprague–Dawley ratsExpression of Oatp1a4 protein in brain microvessels isolated from prepubertal male and female Sprague–Dawley rats. Western blot showed a previously reported Oatp1a4 band of 90 kDa and band related to tubulin at 50 kDa in prepubertal male (M1–4) and female (F1–4) Sprague–Dawley rats. Results are expressed as mean ± SD of the ratio of Oatp1a4 protein expression to tubulin protein expression from four animals per treatment group. MWM molecular weight markerBack to article page
