Product overview
Abcam’s Osteoactivin Human ELISA Kit (ab193711) is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human Osteoactivin in sera, plasma and cell culture supernatants.
This assay employs an antibody specific for Human Osteoactivin coated on a 96-well plate. Standards and samples are pipetted into the wells and the immobilized antibody captures Osteoactivin present in the samples. The wells are washed and biotinylated anti-Human Osteoactivin antibody is added. After washing away any unbound biotinylated antibody, an HRP-conjugated streptavidin is pipetted to the wells. After incubation, the wells are again washed, followed by the addition of a TMB substrate solution to the wells. Color will develop in proportion to the amount of Osteoactivin bound in each well. Addition of the Stop Solution will change the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Research areas
-
Function
Could be a melanogenic enzyme. -
Tissue specificity
Up-regulated in various cancer cells, including in glioblastoma multiforme. Expressed in many melanoma cells, as well as in tissue macrophages, including liver Kuppfer cells and lung alveolar macrophages, in podocytes and in some cells of the ciliary body of the eye (at protein level). Hardly detectable in healthy brain. -
Involvement in disease
Glioblastoma multiforme patients that exhibit increased mRNA and protein levels (>3-fold over normal brain) in biopsy samples have a significantly higher risk of death (PubMed:16609006). In the context of cancer immunotherapy, including that of melanoma, has been proposed to be used as a cell surface protein antigen targeted by antibodies coupled to cytotoxic drugs (PubMed:16489096). -
Sequence similarities
Belongs to the PMEL/NMB family.
Contains 1 PKD domain. -
Cellular localization
Cell membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Detected at the cell surface in different types of cancers cells, including glioblastoma multiforme cells and most melanoma cell lines. - Information by UniProt
