Product Summary
The Quantikine GDF-8/Myostatin Immunoassay is a 4.5 hour solid phase ELISA designed to measure GDF-8 levels in cell culture supernates, tissue homogenates, serum, and plasma. It contains NS0-expressed recombinant GDF-8 and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant GDF-8 accurately. Results obtained using natural GDF-8 showed dose-response curves that were parallel to the standard curves obtained using the recombinant Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for natural GDF-8.
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 a 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 kit components

Recovery
The recovery of GDF-8 spiked to levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
|---|---|---|
| Cell Culture Samples (n=4) | 110 | 100-118 |
| Serum and Plasma (n=12) | 91 | 80-117 |
| Tissue Homogenates (n=4) | 100 | 90-120 |
Linearity
To assess the linearity of the assay, samples containing high
concentrations of GDF-8 were serially diluted with Calibrator Diluent to
produce samples with values within the dynamic range of the assay.
Samples were diluted prior to assay.

Background: GDF-8/Myostatin
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.
Long Name:

Alternate Names:

Application:
Sample Tested: Heparin Plasma,EDTA Plasma,Serum
Ran assay successfully with human plasma (Heparin and EDTA) and human serum (SST) samples, with and without binding protein separation step. High linearity of standard curve (example shown produced by undergrad researchers) when run in triplicate.
