Vaccination effect of normal rats with pcDNA-CCOL2A1 vaccine at the maximum doses of 3mg/kg on plasma production of anti-CII IgG antibodies on 2nd week after vaccination

Anti-CII antibodies	Rat-IgG Anti-Rat	Rat-IgG Anti-chicken
NC	0.1077±0.0565	<0.01
DNA vaccine	0.07355 ±0.0558	<0.01

Each plasma was not diluted, and the values were expressed as mean units of activity (units/ml, n = 6, ${\displaystyle \overline{x}}$ +/−s). Statistical analysis was compared with control. P > 0.05 compared with control. These data are representative of 3 experiments. Three separate experiments yielded similar results.
