Quantitative colorimetric assay. This kit is for the detection of Human IL1A / IL-1 Alpha. No significant cross-reactivity or interference between IL1A / IL-1 Alpha and analogs was observed. This claim is limited by existing techniques therefore cross-reactivity may exist with untested analogs. Sample types: plasma, serum. Range: 10 - 250 pg/ml. Precision: Intra-Assay: CV%<9% Inter-Assay: CV%<10%. Time: 1.5 hours
