Product Summary
The Quantikine Human GM-CSF Immunoassay is a 3.5 or 4.5 hour solid phase ELISA designed to measure GM-CSF levels in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human GM-CSF and antibodies raised against the recombinant factor. It has been shown to quantitate recombinant human GM-CSF accurately. Results obtained using natural human GM-CSF showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural GM-CSF.
Precision
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Linearity
To assess the linearity of the assay, five samples were spiked with high concentrations of GM-CSF in various matrices and diluted with the appropriate Calibrator Diluent to produce values within the dynamic range of the assay.
