Figure 1From: Circulating angiopoietin-1 and angiopoietin-2 in critically ill patients: development and clinical application of two new immunoassaysCorrelation of angiopoietin-1 concentrations measured by immunoluminometric and immunoradiometric methods. Twenty serum samples were analyzed for the angiopoietin-1 (Ang-1) concentration by immunoluminometric sandwich assay (ILMA) and by immunoradiometric sandwich assay (IRMA). Correlation between both methods was excellent (P < 0.0001, r2 = 0.95).Back to article page
