RAW macrophages were transiently transfected with pCMV5-HspA1A using 1:1, 1:2 and 1:3 ratios of 2 μg DNA to lipofectamine. 24 hours after transfection, macrophages were stimulated with 100 ng/ml LPS for 6 hours and culture supernatants were assayed for secreted (A) TNFα and (B) RANTES by ELISA. Graph depicts mean ± SD (n=4) and statistical analysis was performed by one way ANOVA with Dunnett’s test for multiple comparisons. (ns p>0.05, * p<0.05, ** p<0.01, *** p<0.001, ****p=0.0001)
