From: DNA vaccine constructs against enterovirus 71 elicit immune response in mice
The highest dilution of mice sera that resulted inmore than 50% CPE. The sera of DNA vaccine groups (pVAX1/VP1-S and pVAX1/VP1-4) had resulted in approximately 50% CPE at a dilution of 1:32. Almost 100% CPE was observed in the sera of negative control groups (pVAX1 and PBS) at the dilution of 1:2 and the subsequent dilutions.
