Product Summary
The Quantikine Human Osteocalcin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Osteocalcin in cell culture supernates and EDTA plasma. It contains synthetic human Osteocalcin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Osteocalcin 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 Osteocalcin.

Precision
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

Recovery

The recovery of human Osteocalcin spiked to levels throughout the range of the assay in various matrices was evaluated.

Sample Type Average % Recovery Range %
Cell Culture Media (n=4) 105 98-120
EDTA Plasma (n=4) 102 80-116
Linearity
To assess the linearity of the assay, samples spiked with high concentrations of human Osteocalcin were diluted with Calibrator Diluent to produce samples with values within the dynamic range of the assay.

    Bone gamma-Carboxyglutamate [gla] Protein
  • Entrez Gene IDs:
    632 (Human); 12096 (Mouse); 25295 (Rat)
  • Alternate Names:
    BGLAP; BGP; bone gamma-carboxyglutamate (gla) protein (osteocalcin); bone gamma-carboxyglutamate (gla) protein; Bone Gla protein; Gamma-carboxyglutamic acid-containing protein; OC; OCN; Osteocalcin

Assay Procedure
Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
    3. 100 µL Assay Diluent
  3.   Add 100 µL of Assay Diluent to each well.
    4. 50 µL Standard, Control, or Sample
  4.   Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 200 µL Conjugate
  6.   Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
  7.   Aspirate and wash 4 times.
    8. 200 µL Substrate Solution
  8.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
    9. 50 µL Stop Solution
  9.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
