Effects of a peptide incorporating the 3₁₀ helical turn on CFU-A colony formation and the inhibitory effects of MIP-1α. Numerical values represent the concentrations of the peptide and/or MIP-1α in micrograms per milliliter in the final assay. All additions were directly to the assay plates at the initiation of the assay. In this assay, the average number of CFU-A colonies per control plate was 9 ± 1.7. Results are presented as a percentage of CFU-A colony growth plus or minus SEM. This assay is representative of 2 repeat assays.
