Osteocalcin EIA kits for bone and endocrine research
Overview
Takara Bio’s osteocalcin EIA kits may be used to study the roles that osteocalcin (OC) plays in bone metabolism, insulin synthesis, glucose metabolism, and male fertility. Unlike other assays, our EIA kits don't just measure total osteocalcin. Rather, our kits enable you to measure either the carboxylated (cOC) or under-carboxylated (ucOC) forms of the protein. This provides you with the power to quantify active protein (cOC for bone metabolism; ucOC for glucose metabolism).
Takara Bio’s osteocalcin EIA kits provide you with:
- Sensitivity: measure as little as 0.125–0.5 ng/ml of protein
- Specificity: highly purified antibodies are specific to the protein of interest
- Convenience: supplied in a 96-well format (8 x 12 strips)
- Scalability: ready to use in a high-throughput format
Move beyond qualitative analysis
Our EIA kits enable you to quantify osteocalcin in biological samples (such as blood and urine), cell culture supernatants, and cultured cells. Quantitative results are obtained in just 3 hours.

- Glu-OC EIA Kits for quantitative measurement of ucOC

Units: ng/ml
Both types of osteocalcin (Glu-, inactive; Gla-, active) were monitored in the blood serum of young or aged rats over several weeks. The values in the table are reduced concentrations multiplied by the dilution ratio. Serum levels of both Gla- and Glu-osteocalcin tend to be higher in young rats than in aged rats, suggesting activation of bone metabolic turnover.
Sandwich ELISA format
The osteocalcin EIA kits use a sandwich-type format, with an osteocalcin-specific antibody as a capture antibody on a solid-phase plate. An enzyme-labeled antibody specific to either Gla-OC or Glu-OC is used as the detection antibody, allowing detection of either Gla- or Glu-osteocalcin with very high sensitivity.
