This assay has high sensitivity and excellent specificity for detection of Fibroblast Growth Factor 1, Acidic. No significant cross-reactivity or interference between Fibroblast Growth Factor 1, Acidic and analogues was observed. Sample types: serum, plasma and other biological fluids. Range: 2.74-2,000 pg/mL. Sensitivity: 1.06 pg/mL. Intra-assay Precision (Precision within an assay): 3 samples with low, middle and high level Fibroblast Growth Factor 1, Acidic were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays): 3 samples with low, middle and high level Fibroblast Growth Factor 1, Acidic were tested on 3 different plates, 8 replicates in each plate.CV (%) = SD/meanX100;Intra-Assay: CV<10%;Inter-Assay: CV<12%.
