FIG. 2.

Interaction of polyclonal anti-CRP antibodies with 60-kDa heat shock proteins. Binding of different dilutions of goat (WAKO, panel A) and two different rabbit (DAKO, panel B; SIGMA, panel C) anti-CRP polyclonal antibodies to recombinant human Hsp60 (▪, 2 μg/ml) or recombinant M. tuberculosis Hsp65 (▴, 2 μg/ml) target antigens as detected by ELISA. Control wells were uncoated (▾). Optical densities were measured at 490 nm; means ± standard errors of the means of OD values are shown. Results are the sum of three independent experiments, each performed in duplicate.
