FIG. 5.

Quantitative collagen binding as a function of growth conditions. S. aureus Wright was transformed with each isogenic cna clone and examined by quantitative collagen binding assay using cells taken from exponentially growing cultures (A) and from post-exponential-phase cultures (B and C). (D) Results obtained when the cells used in the collagen binding assay were harvested from Columbia agar. Results of ¹²⁵I-collagen binding assays are reported as disintegrations per minute (dpm). Results shown represent the average of two experiments, each including duplicate assays. Results are shown as mean ± standard error of the mean.
