Brevican core protein (BCAN)
Links to databases
Brevican core protein (also known as Brain-enriched hyaluronan-binding protein) is a member of the lectican family of chondroitin sulfate proteoglycans that is specifically expressed in the central nervous system. The protein is localised to the surface of neurons in the brain and levels of the most abundant isoform decrease with age, with high expression observed from birth through 8 years of age followed by down-regulation to lower levels that are maintained in the normal adult cortex by the age of 20.BCAN is thought to play a role in central nervous system development (including the postnal period, and may regulate neuronal synapse plasticity. The protein is also is highly expressed in gliomas and may promote the growth and cell motility of brain tumor cells.
Sample type
Recommended sample types are 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.

Analytical Measuring Range
Please note: the technical data reported below refers to the measured value in the in vitro validation assays. 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 (https://www.olink.com/question/what-is-npx).
