Testican-1 (SPOCK1)

Links to databases

Testican-1 (also known as protein SPOCK) forms the protein core of a plasma proteoglycan that is related to glycoproteins such as SPARC. Its similarity to thyropin-type cysteine protease inhibitors suggests that one function of SPOCK1 may be related to protease inhibition. This protein may play a role in cell-cell and cell-matrix interactions. It is also believed to contribute to several neuronal mechanisms in the central nervous system, including forebrain development, neurogenesis and neuron differentiation and migration.

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.
