Alpha-2-macroglobulin receptor-associated protein (Alpha-2-MRAP)

Links to databases

Alpha-2-macroglobulin receptor-associated protein (also known as LDL-receptor-related protein-associated protein) is a glycoprotein that functions as a chaperone molecule.It is involved in the trafficking of some LDL receptor family members, including LRP1 and LRP2. Alpha-2-MRAP binds to multiple members of the low density lipoprotein receptor family, inhibiting their binding to all of their known ligands. This may prevent receptor aggregation and degradation in the endoplasmic reticulum. There is also genetic evidence linking Alpha-2-MRAP to negative regulation of beta-amyloid clearance.

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

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