Figure 1From: Sensitivity and specificity of tritiated thymidine incorporation and ELISPOT assays in identifying antigen specific T cell immune responsesAntibody immunity to both foreign and tumor antigens is an indicator of a concomitant T cell response. Results from the (A) proliferation assay and (B) ELISPOT assay for antigens HER-2/neu, tt and CMV are plotted on the log-scaled horizontal axis. Antigen specific IgG antibody responses are plotted on the log-scaled vertical axis. The diagonal line indicates line of regression.Back to article page
