 Specificity    This assay has high sensitivity and excellent specificity for detection of POSTN. No significant cross-reactivity or interference between POSTN and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between POSTN and all the analogues, therefore, cross reaction may still exist in some cases.

 Samples    Serum, plasma, cell culture supernatants, body fluid and tissue homogenate
 Assay Type    Quantitative Competitive
 Sensitivity    1.0 ng/mL.

 Preparation and Storage    Store all reagents at 2-8 degree C.
 Sample Preparation    We suggest pre-experimenting with neat (undiluted) samples, 1:2 or 1:4 dilutions. Please avoid diluting your samples more than 1:10 as it would exceed the dilution limit set for this kit. If the expected concentration of the target is beyond the detection range of the kit, please contact our technical support team
 Product Note    Our ELISA Kit assays are dynamic research tools and sometimes they may be updated and improved. If the format of this assay is important to you then please request the current manual or contact our technical support team with a presales inquiry before placing an order. We will confirm the current details of the assay. We cannot guarantee the sample manual posted online is the most current manual.
 Other Notes    Small volumes of POSTN elisa kit vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.
 Searchable Terms for POSTN purchase    MBS722502 is a ready-to-use microwell, strip plate Quantitative Competitive ELISA (enzyme-linked immunosorbent assay) Kit for analyzing the presence of the Periostin (POSTN) ELISA Kit target analytes in biological samples. The concentration gradients of the kit standards or positive controls render a theoretical kit detection range in biological research samples containing POSTN, with an estimated sensitivity of 1.0 ng/mL. The ELISA analytical biochemical technique of the MBS722502 kit is based on POSTN antibody-POSTN antigen interactions (immunosorbency) and an HRP colorimetric detection system to detect POSTN antigen targets in samples. The ELISA Kit is designed to detect native, not recombinant, POSTN. Appropriate sample types may include undiluted body fluids and/or tissue homogenates, secretions such as Serum, plasma, cell culture supernatants, body fluid and tissue homogenate. Quality control assays assessing reproducibility identified the intra-assay CV (%) and inter-assay CV(%).

Related Product Information for POSTN elisa kit

   Intended Uses: This POSTN ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human POSTN. This ELISA kit for research use only, not for therapeutic or diagnostic applications!

Principle of the Assay: POSTN ELISA kit applies the competitive enzyme immunoassay technique utilizing an anti-POSTN antibody and an POSTN-HRP conjugate. The assay sample and buffer are incubated together with POSTN-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the POSTN concentration since POSTN from samples and POSTN-HRP conjugate compete for the anti-POSTN antibody binding site. Since the number of sites is limited, as more sites are occupied by POSTN from the sample, fewer sites are left to bind POSTN-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The POSTN concentration in each sample is interpolated from this standard curve.

 NCBI Summary for POSTN    This gene encodes a secreted extracellular matrix protein that functions in tissue development and regeneration, including wound healing, and ventricular remodeling following myocardial infarction. The encoded protein binds to integrins to support adhesion and migration of epithelial cells. This protein plays a role in cancer stem cell maintenance and metastasis. Mice lacking this gene exhibit cardiac valve disease, and skeletal and dental defects. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2015]
Section Bar
 UniProt Comments for POSTN    POSTN: Binds to heparin. Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization. 4 isoforms of the human protein are produced by alternative splicing.

Protein type: Cell adhesion; Secreted, signal peptide; Motility/polarity/chemotaxis; Secreted

Chromosomal Location of Human Ortholog: 13q13.3
