Table 1 Intra- and inter-assay precisions of PA28 γ sandwich ELISA

From: Increased proteasome activator 28 gamma (PA28γ) levels are unspecific but correlate with disease activity in rheumatoid arthritis

His-PA28γ[ng/ml]
  0 3.125 6.25 12.5 25 50 100 200
Intra-assay CV [%], n = 3
day 1 0.4 10.4 16.7 31.2 19.9 9.3 16.8 10.4
day 2 8.7 14.7 7.6 4.6 13.8 7.9 4.9 5.2
day 3 18.1 4.9 7.0 16.5 3.9 6.5 9.1 10.9
Inter-assay CV [%], n = 3
day 1-3 10.9 10.9 10.9 18.1 15.8 11.9 14.6 13.1
  1. Precisions were calculated as the mean coefficient of variation (CV) of different PA28γ antigen concentrations measured with Sandwich ELISA in 3 independent experiments from duplicate wells at 3 days.
