Intact mass protein profiling in wild male rat urine. Individual urine samples from male wild caught rats were analysed as described in Material and Methods. Results are shown in parallel for each sample. Panel A: ESI-MS intact protein mass profiling: deconvoluted spectra are shown for each sample and main masses are highlighted at the top of the panel. Panel B: isoelectric focusing analysis.
