Figure 3From: Circulating angiopoietin-1 and angiopoietin-2 in critically ill patients: development and clinical application of two new immunoassaysAssay linearity and standard reference curves for angiopoietin-1 and angiopoietin-2 immunoassays. Dilution studies demonstrated both excellent assay linearity as well as adequate parallelism between standard references (recombinant human angiopoietin-1 or recombinant human angiopoietin-2) and serially diluted serum sample curves for (a) angiopoietin-1 (Ang-1) and (b) angiopoietin-2 (Ang-2) assays.Back to article page
