Junctional adhesion molecule B (JAM-B)

Links to databases

Junctional adhesion molecule B (also known as junctional adhesion molecule 2) is a type I membrane protein that localizes to the tight junctions of epithelial and endothelial cells. It acts as an adhesive ligand for interacting with a variety of immune cell types, and may play a role in lymphocyte homing to secondary lymphoid organs. It is thought to promote lymphocyte transendothelial migration and may also be involved with endothelial cell polarity, by associating to cell polarity protein PAR-3, together with JAM3.

Sample type

Recommended sample types are human EDTA plasma and serum. A range of additional sample types are compatible with the technology (PEA), including citrate plasma, heparin plasma, cerebrospinal fluid, (CSF), tissue and cell lysates, fine needle biopsis, microdialysis fluid, cell culture media, dried blood spots, synovial fluid, saliva, plaque extract and microvesicles. Please note that protein expression levels are expected to vary in different sample types. Certain assays are differentially affected by interfering substances such as hemolysate. Download any of our Data Validation documents or contact support@olink.com for more information.

NOTE: The calibrator curve below shows the performance of the assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens. Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please visit our FAQ page.

Precision

    • Within run precision Coefficient of Variation (CV)
    • 8%
    • Between run precision Coefficient of Variation (CV)
    • 8%

Precision (repeatability) is calculated from linearized NPX values over LOD.
