This assay has high sensitivity and excellent specificity for detection of Noradrenaline. No significant cross-reactivity or interference between Noradrenaline and analogues was observed. Sample types: serum, plasma, cell lysates, cell culture supernates and other biological fluids. Range: 61.7-5000 pg/mL. Sensitivity: 26.1 pg/mL. Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Noradrenaline were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Noradrenaline were tested on 3 different plates, 8 replicates in each plate.CV (%) = SD/meanX100;Intra-Assay: CV<10%;Inter-Assay: CV<12%. Time: 2 hours
