IHC/ICC: Osteocalcin

Osteocalcin in Human MSC.
Osteocalcin in Human MSC.

Osteocalcin was detected in immersion fixed human mesenchymal stem cells (MSC) differentiated into osteocytes using Human Osteocalcin Monoclonal Antibody (Catalog # MAB1419) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

Osteocalcin in Human Cartilage.
Osteocalcin in Human Cartilage.

Osteocalcin was detected in immersion fixed paraffin-embedded sections of human cartilage using Human Osteocalcin Monoclonal Antibody (Catalog # MAB1419) at 8 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of chondrocytes. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.

This antibody specifically recognizes human Osteocalcin. Reactivity with Osteocalcin from other species has not been determined.


Osteocalcin in Human Osteosarcoma.
Osteocalcin in Human Osteosarcoma.

Osteocalcin was detected in immersion fixed paraffin-embedded sections of human osteosarcoma using Human Osteocalcin Monoclonal Antibody (Catalog # MAB1419) at 25 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Secondary Antibodies
R&D Systems offers a wide range of biotinylated, HRP-conjugated, fluorochrome-labeled, and unlabeled species-specific secondary antibodies. Our NorthernLights™ fluorescent secondary antibodies are available with three distinct excitation and emission maxima, making them ideal for multi-color fluorescence microscopy.

Osteocalcin in MG‑63 Human Cell Line.

Bone gamma-Carboxyglutamate [gla] Protein (Osteocalcin) was detected in immersion fixed MG‑63 human osteosarcoma cell line using Human Osteocalcin Monoclonal Antibody (Catalog # MAB1419) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).
