Product Summary for Human GM-CSF Quantikine ELISA Kit
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.

Sample Values
Serum/Plasma - Forty serum and plasma samples from apparently healthy volunteers were
evaluated for the presence of human GM-CSF in this assay. All samples measured less than the
lowest Human GM-CSF Standard, 7.8 pg/mL. No medical histories were available for the donors
used in this study.
Cell Culture Supernates - Human peripheral blood mononuclear cells (1 x 106
cells/mL) were
cultured in RPMI supplemented with 10% fetal bovine serum, 50 μM beta-mercaptoethanol,
2 mM L-glutamine, 100 U/mL penicillin, and 100 μg/mL streptomycin sulfate and cultured
unstimulated or stimulated with 10 μg/mL PHA. Aliquots of the cell culture supernates were
removed on days 1 and 5 and assayed for levels of human GM-CSF.
| Condition | Day 1 (pg/mL) | Day 5 (pg/mL) |
| Unstimulated | 39 | 43 |
| Stimulated | 71 | 31 |
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.

Recovery for Human GM-CSF Quantikine ELISA Kit
The recovery of GM-CSF spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Media (n=5) | 97 | 85-104 |
| Citrate Plasma (n=5) | 101 | 92-106 |
| EDTA Plasma (n=5) | 100 | 94-105 |
| Heparin Plasma (n=5) | 98 | 92-104 |
| Serum (n=5) | 98 | 93-103 |
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.

Background: GM-CSF
GM-CSF (Granulocyte-Macrophage Colony Stimulating Factor) induces the development of monocytes, neutrophils, eosinophils, and myeloid and dermal dendritic cells. It also acts as a neutrophil and dendritic cell chemoattractant. GM-CSF promotes Th1 and Th17 cell mediated autoimmune inflammation as well as the inflammatory activation of dendritic cells, microglia, alveolar macrophages, and eosinophils. In addition, it cooperates with G-CSF in promoting tumor cell proliferation and invasion. GM-CSF signals through a receptor complex composed of GM-CSF R alpha and the Common beta Chain (beta c) with Syndecan-2 as a potential co-receptor. The beta c subunit is shared by the receptor complexes for IL-3 and IL-5.
