Tyrosine-protein phosphatase non-receptor type substrate 1 (SHPS-1)

Links to databases

 

SHPS-1 is an immunoglobulin-like cell surface receptor for CD47. The CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. This protein may play a key role in intracellular signaling during synaptogenesis and in synaptic function, and it also supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment. Furthermore, SHPS-1 is involved in the negative regulation of receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors or insulin, as well as mediating negative regulation of phagocytosis, mast cell activation and dendritic cell activation.

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.

Analytical Measuring Range

Please note: the technical data reported below refers to the measured value in the in vitro validation assays. Since the CVD III panel uses human samples diluted 100-fold, a multiplication factor of 100 should be applied when comparing the addressable biological concentration to this validation data.

Precision

    • Within run precision Coefficient of Variation (CV)
    • 8%
    • Between run precision Coefficient of Variation (CV)
    • 9%

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