Natural mouse and rat GDF-15, recombinant mouse mature GDF-15, precursor GDF-15, and GDF-15/BMP-2 heterodimer. It does not detect monomeric recombinant mouse GDF-15.
< 0.5% cross-reactivity observed with available related molecules.< 50% cross-species reactivity observed with species tested.
No significant interference observed with available related molecules.
The Quantikine Mouse/Rat GDF-15 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure mouse and rat GDF-15 in cell culture supernates, serum, plasma, and urine. It contains E.
coli-expressed recombinant mouse GDF-15 and antibodies raised against the recombinant factor. This immunoassay has been shown to accurately quantitate the recombinant factor. Results obtained using natural mouse or rat GDF-15 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 naturally occurring mouse and rat GDF-15.
Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested twenty times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in twenty separate assays to assess inter-assay precision. Assays were performed by at least three technicians using two lots of components.
The recovery of GDF-15 spiked to levels throughout the range of the assay in various matrices was evaluated.
Average % Recovery
Mouse Cell Culture Media (n=4)
Mouse EDTA Plasma (n=4)
Mouse Heparin Plasma (n=4)
Mouse Serum (n=4)
Mouse Urine (n=4)
To assess the linearity of the assay, samples containing and/or spiked with high concentrations of GDF-15 in each matrix were diluted with Calibrator Diluent and assayed.
Preparation and Storage
Store the unopened product at 2 - 8 °C. Do not use past expiration date.
Growth/differentiation factors (GDF-1 to GDF-15) are members of the BMP family of TGF-beta superfamily proteins. They are produced as inactive preproproteins which are then cleaved and assembled into active secreted homodimers. GDF dimers are disulfide-linked with the exception of GDF-3 and -9. GDF proteins are important during embryonic development, particularly in the skeletal, nervous, and muscular systems.
