These periostin, osteoblast specific factor ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. periostin, osteoblast specific factor is an alias of the human POSTN gene, which encodes the protein, periostin. Notably, periostin, osteoblast specific factor is known to play a role in cell adhesion and extracellular matrix organization, among other functions. The POSTN protein is 836 amino acid residues in length and 93.3 kilodaltons in mass. However, as many as 7 protein isoforms have been identified. Its subcellular localization is in the golgi, extracellular matrix, and is secreted. In terms of tissue specificity, it is reported to be widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus, thyroid tissue and breast. This protein is known to be glycosylated. Other names for this target antigen include OSF-2, OSF2, and PDLPOSTN.
There are periostin, osteoblast specific factor ELISA kits that can detect a target at concentrations as low as 31.3 pg/mL and as high as 200 ng/mL. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
