Quantitative colorimetric assay. This assay has high sensitivity and excellent specificity for detection of pig FAS. No significant cross-reactivity or interference between pig FAS and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between pig FAS and all the analogues, therefore, cross reaction may still exist. Sample types: plasma, serum. Range: 0.625 - 40 ng/ml. Precision: Intra-Assay: CV<8% / Inter-Assay: CV<10%. Time: 4.5 hours
