Modulation of Jurkat cell CD3-zeta protein expression by physiologic estradiol concentrations. Expression of CD3-zeta protein expression by Jurkat cells incubated in the presence of either 4 pg/ml or 40 pg/ml estradiol for 48 hours defined by Western immunoblotting. The bar graph presents the quantitation of triplicate digitized gel images expressed as mean ± standard deviation. The insert shows a representative Western blot gel image.
