Preparation and Storage
Background: Osteocalcin
Osteocalcin, also named Bone gamma-carboxyglutamic Acid Protein, is a secreted protein whose expression is restricted to cells of the osteoblast lineage. It has been frequently used as a marker for osteoblast lineage cells.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 100 µL of Assay Diluent to each well.
- 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.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- 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.
- Aspirate and wash 4 times.
- Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- 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.

FAQs
-
Why can't heparin plasma samples be used with the Human Osteocalcin Quantikine ELISA Kit, Catalog # DSTCN0?
It was found that heparin tends to accelerate the enzymatic breakdown of osteocalcin and it is therefore not recommended with this kit.
-
Why is serum not a validated sample type with the Human Osteocalcin Quantikine ELISA Kit, Catalog # DSTCN0?
Serum values have shown to be consistently lower than plasma samples in this kit and therefore are not an ideal sample type.
-
Are either of R&D Systems Human Osteocalcin ELISA assays, catalog #s DSTCN0 or DY1419, specific for un-carboxylated or gamma-carboxylated form of Osteocalcin?
The Human Osteocaclin Quantikine ELISA (catalog # DSTCN0) assay recognizes natural and recombinant human Osteocalcin, and the assay recognizes Des-γ-carboxylated-Osteocalcin. The Human Osteocalcin DuoSet ELISA (catalog # DY419) also recognizes natural and recombinant human Osteocalcin, however, we have not determined if the DuoSet also recognizes Des-γ-carboxylated-Osteocalcin.
