POSTN ELISA Kit (Human)

• Reproducibility:

  Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Periostin (POSTN) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Periostin (POSTN) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

• Gene ID:

  10631

• Accession Number:

  NP_001129406.1

• Reactivity:

  Homo sapiens|Human

• Target:

  Induces cell attachment and spreading and plays a role in cell adhesion (PubMed:12235007) . Enhances incorporation of BMP1 in the fibronectin matrix of connective tissues, and subsequent proteolytic activation of lysyl oxidase LOX (By similarity) .

• Type:

  ELISA Kit

• Applications:

  Enzyme-linked Immunosorbent assay-Sandwich

• Detection Method:

  Colorimetric

• Assay Principle:

  The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Periostin (POSTN) . Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Periostin (POSTN) . Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Periostin (POSTN), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm +/- 10nm. The concentration of Periostin (POSTN) in the samples is then determined by comparing the O.D. of the samples to the standard curve.
