About This Kit
The Human Periostin (POSTN/OSF 2) ELISA quantitates POSTN/OSF 2 in serum and plasma.
Principle of the method
The Human POSTN/OSF 2 solid phase sandwich ELISA (enzyme linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target specific antibody has been pre coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody. A substrate solution is added that reacts with the enzyme antibody target complex to produce a measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Achieve fast and reliable results in just 90 minutes with our Rapid ELISA kit, featuring a streamlined protocol that requires only one wash step.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Target information
Periostin (PN), also designated osteoblast-specific factor 2 (OSF-2), is a disulfide linked protein originally isolated as a osteoblast-specific factor. Periostin is a secreted protein that binds heparin and functions as a ligand for alpha(V)beta(3) and alpha(V)beta(5) integrins. In preosteoblasts, Periostin acts as a cell adhesion molecule and plays a role in osteoblast recruitment, spreading and attachment. Periostin is mainly detected in lower gastrointestinal tract, aorta, stomach, placenta, uterus and breast tissues but is up-regulated in epithelial ovarian tumors and overexpressed in breast cancer. Expression of Periostin is increased by bone morphogenetic protein (BMP2) and transforming growth factor beta 1(TGF beta 1). Periostin contains a typical signal sequence, followed by a cysteine-rich domain, a fourfold repeated domain, which shows homology with the insect protein fasciclin, and a C-terminal domain.
