Quantitative colorimetric assay. This assay has high sensitivity and excellent specificity for detection of Mouse GC. No significant cross-reactivity or interference between Mouse GC and analogues was observed. Note: Limited by current skills and knowledge, it is impossible for us to complete the cross- reactivity detection between Mouse GC and all the analogues, therefore, cross reaction may still exist. Sample types: plasma, serum. Range: 31.25 - 2000 pg/ml. Precision: Intra-Assay: CV<10% Inter-Assay: CV<10%.
