sCD155 levels in sera were dependent on tumor size in a mouse model.

<p>(<b>A</b>) MethA transfectant secreting sCD155 (sCD155-MethA) or control protein (Mock-MethA) were inoculated into peritoneal cavity and then ascites was collected. sCD155 levels in ascites of mice that had been inoculated with these transfectantss were measured by ELISA. (<b>B</b>) BALB/c mice were inoculated subcutaneously with sCD155-MethA transfectant. Tumor size and sCD155 levels in serum were measured and the correlation coefficient was calculated.
