Low-concentration reference controls for C-reactive protein assays are prepared from higher-level starting materials by simple filtration using silica-type filter media formerly used for removing lipids. This process avoids the need for antibodies to capture the protein and resuspend it. Surprisingly, the removal of CRP by the silica-type filter media is selective toward CRP, having little or negligible effect on other proteins in the starting matrix, and accordingly little or negligible change in the total protein content.
