機能
Binds tightly to hydroxyapatite. Appears to form an integral part of the mineralized matrix. Probably important to cell-matrix interaction.
Acts as a cytokine involved in enhancing production of interferon-gamma and interleukin-12 and reducing production of interleukin-10 and is essential in the pathway that leads to type I immunity. -
組織特異性
Bone. Found in plasma. -
配列類似性
Belongs to the osteopontin family. -
翻訳後修飾

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Osteopontin antibody (ab8448)
Human Breast tumour section. Osteopontin is a normal component of elastic fibers in the breast (shown heavily stained in this section). There is also weak staining of the extracellular matrix. Osteopontin is not believed to be expressed inside breast tumour cells, and there is no staining in the intracellular region of the breast cells in this section.
Osteopontin antibody (ab8448) used at 1:100-1:300. No antigen retrieval is required.

Immunocytochemistry/ Immunofluorescence - Anti-Osteopontin antibody (ab8448)ICC/IF image of ab8448 stained MCF7 cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab8448, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM. -
Cellular Activity - Anti-Osteopontin antibody (ab8448)This image is courtesy of Agnihotri et al, JBC 2001OPN is cleaved by MMP to yield 2 fragments, which migrate at 40kD(N terminal) and 32kD (C terminal). The C terminal fragment can undergo further cleavage by both of these MMPs (see Agnihotri et al, JBC 2001 for further details). The epitope recognised by ab8448 is shown in violet. This antibody detects the full length OPN and the 32kD fragment. It does not recognise the 40kD fragment.
