Inverse correlation between plasma-associated radioactivity (TCA-precipitable cpm) and whole spleen-associated radioactivity in W/B F1 male mice. Plasma-associated radioactivity is presented as cpm × 10−4/mL of plasma. Whole spleen-associated radioactivity is presented as cpm × 10−4. A significant correlation between plasma and whole spleen-associated radioactivity was found (r = −.91,P < .05) using Pearson correlation analysis.
