Quantitative colorimetric assay. This assay has high sensitivity and excellent specificity for detection of rat SERPINA7. No significant cross-reactivity or interference between rat SERPINA7 and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between rat SERPINA7 and all the analogues, therefore, cross reaction may still exist. Sample types: plasma, serum, tissue homogenates. Range: 4.7 - 300 ng/ml. Precision: Intra-Assay: CV<8% / Inter-Assay: CV<10%. Time: 2.5 hours
