During the last decade, capillary electrophoresis (CE) has emerged as an important alternative to traditional analysis of serum and plasma proteins by agarose or celluloseacetate electrophoresis. CE analysis of plasma proteins can now be fully automated and also includes bar-code identification of samples, preseparation steps, and direct post-separation quantitation of individual peaks, which permits short assay times and high throughput. For laboratory work, it is important to have reference values from healthy individuals. Therefore, plasma samples from 156 healthy blood donors (79 females and 77 males) have been analyzed with the Capillarys instrument and the new high resolution buffer, which yields higher resolution than the b1-b2+ buffer. Albumin concentrations in samples are measured using nephelometry in order to assign protein concentrations to each peak. The 2.5 and 97.5 percentiles for both the percentages of different peaks and the protein concentrations in the peaks are calculated according to the recommendations of the International Federation of Clinical Chemistry on the statistical treatment of reference values. The Capillarys instrument is a reliable system for plasma protein analysis, combining advantages of full automation with high analytical performances and throughput.
