Quantitative colorimetric assay. This assay has high sensitivity and excellent specificity for detection of mouse DHEA-S. No significant cross-reactivity or interference between mouse DHEA-S and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between mouse DHEA-S and all the analogues, therefore, cross reaction may still exist. Sample types: plasma, serum, tissue homogenates. Range: 5 - 1000 ng/ml. Precision: Intra-Assay: CV<15% / Inter-Assay: CV<15%. Time: 2.5 hours
