FIG. 2.

Performance of immunocapture PCR assay on suspensions of C. jejuni in PBS containing 3% BSA. Sample volumes were 1 ml, and samples had cell counts ranging from 0 to 1,000. A signal could be obtained from a single cell following 35 cycles of PCR. The background reading for the 0-cell control was 0.003. OD₄₀₅, optical density at 405 nm.
