Product Specifications
Immunogen
This whole rabbit serum was prepared by repeated immunizations with a synthetic peptide, from the human Osteopontin/OPN protein, conjugated to KLH using maleimide. (Uniprot: P10451)
Localization
Secreted
Specificity
Osteopontin/OPN is directed against human osteopontin. The antibody recognizes the full-length osteopontin protein (which runs at 66 kDa on westerns), as well as the C-terminal fragments of both thrombin and MMP-cleaved OPN. The 32 kDa MMP-cleaved C-fragment is recognized, but not the 40 kDa N-terminal fragment. Reactivity is reported to occur with osteopontin from swine, dog, mouse and rat.

Immunohistochemistry: Osteopontin/OPN Antibody [NB600-1043]
Immunohistochemistry: Osteopontin/OPN Antibody [NB600-1043] - Osteopontin/OPN/OPN antibody was used at a 1:100-1:300 dilution to detect osteopontin by immunohistochemistry. Osteopontin/OPN is a normal component of elastic fibers in the breast (shown heavily stained in this section of human breast tumor cells). There is also weak staining of the extracellular matrix. Osteopontin/OPN is not expressed in breast tumor cells, and there is no staining of the breast cells in this section. No antigen retrieval is required.

Application Notes
This product has been tested for western blotting, immunohistochemistry (formalin-fixed paraffin-embedded sections) and ELISA. The antibody exclusively recognizes C-terminal fragments of both thrombin and MMP-cleaved OPN. The antibody recognizes the full-length osteopontin protein (which runs at 66 kDa on westerns), and 32 kDa for the MMP-cleaved C-fragment, but the 40 kDa N-terminal fragment is not recognized. A 1:1000 dilution will detect strongly approximately 250 ng of OPN protein on a blot. A 1:100-1:300 dilution used for IHC on human breast tumor tissues. No pretreatment is required for IHC when formalin-fixed paraffin-embedded tissue is stained. Specific conditions for reactivity and signal detection should be optimized by the end user.
