Quantitative colorimetric assay. This kit is for the detection of Mouse KL / Klotho. No significant cross-reactivity or interference between KL / Klotho and analogs was observed. This claim is limited by existing techniques therefore cross-reactivity may exist with untested analogs. Sample types: plasma, serum. Range: 50 - 1000 pg/ml. Precision: Intra-Assay: CV%<5.9% Inter-Assay: CV%<7.9%. Time: 1.5 hours
