Quantitative colorimetric assay. This kit is for the detection of Rat SOD1 / Cu-Zn SOD. No significant cross-reactivity or interference between SOD1 / Cu-Zn SOD and analogs was observed. This claim is limited by existing techniques therefore cross-reactivity may exist with untested analogs. Sample types: plasma, serum. Range: 1 - 25 μg/ml. Precision: Intra-Assay: CV%<10% Inter-Assay: CV%<10%. Time: 1.5 hours
