Product Summary
The Quantikine Human FLRG Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human FLRG in cell culture supernates, serum, plasma, urine, and human milk. It contains NS0-expressed recombinant human FLRG and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human FLRG 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 human FLRG.

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
The recovery of FLRG spiked to levels throughout the range of the assay was evaluated.
| Sample Type | Average % Recovery | Range % |
| Cell Culture Media (n=4) | 107 | 98-111 |
| Serum (n=4) | 100 | 91-112 |
| EDTA Plasma (n=4) | 96 | 85-105 |
| Heparin Plasma (n=4) | 102 | 89-114 |

Linearity
To assess the linearity of the assay, samples containing high concentrations of FLRG were serially diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

Additional Infomation
- Molecule Information
- Follistatin-related Gene Protein/FLRG
- Aliases
- Follistatin-like 3; FSTL3
- Entrez Gene IDs
- 10272 (Human); 83554 (Mouse)
- Background
- Follistatin-related Gene Protein
- Follistatin-related gene protein (FLRG) has been shown to bind and inhibit the TGF-beta family ligands including activin, BMP-2, -6, -7, and GDF-8. FLRG is expressed most highly in heart, lung, kidney, and placenta, and is upregulated by TGF-beta and Activin via Smad proteins.
