  • 产品描述:

    The human Periostin (POSTN) ELISA Kit is engineered for accurate measurement of human POSTN levels from samples including serum, plasma, or tissue homogenates. It uses the Sandwich-ELISA mechanism in combination with the enzyme-substrate chromogenic reaction to measure the POSTN content in the sample. The color intensity is positively correlated with POSTN content in the sample. The POSTN concentration can be calculated according to the standard curve. This kit is tested with high sensitivity, strong specificity, good linearity, high precision and recovery, as well as lot-to-lot consistency.

    POSTN, also called OSF2, is a secreted extracellular matrix (ECM) protein expressed in fibroblasts during bone and teeth development. It plays a dynamic role in mediating the communication between cells and the surrounding microenvironment rather than directly participating in the formation of the ECM. POSTN is also involved in bone density and intervertebral disc (IVD) homeostasis. It also mediates inflammation and reconstruction during bronchial asthma, as well as promotes bone development, reconstruction, repair, and strength. Expression of POSTN has been also associated with the progression and drug resistance of different tumors.
