Box plot with median and percentiles (10–90%) for MIP-2, MCP-1 and RANTES as determined by EIA in mice kidney homogenate at 0 h (untouched), 24 h, 48 h and 6 days (infected and NaCl injected). The limits of detection for mouse MIP-2, MCP-1 and RANTES were 2·0, 1·5 and 2·0 pg/ml, respectively. For each time-point 5–6 mice were used, both kidneys were analysed individually.
