Quantitative colorimetric assay. This kit is for the detection of Rat CSF3 / G-CSF. No significant cross-reactivity or interference between CSF3 / G-CSF 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 ng/ml. Precision: Intra-Assay: CV%<9% Inter-Assay: CV%<10%. Time: 1.5 hours
