Uniprot Function Description

Responsible for the proteolytic processing of the amyloid precursor protein (APP). Cleaves at the N-terminus of the A-beta peptide sequence, between residues 671 and 672 of APP, leads to the generation and extracellular release of beta-cleaved soluble APP, and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase (PubMed:10656250, PubMed:10677483, PubMed:20354142). Cleaves CHL1 (By similarity).

Sample type

Recommended sample types are 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 biopsies, 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 between 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.

Precision

Precision (repeatability) is calculated from quantified data (pg/mL) within the limits of quantification: LOQ.

Within run precision Coefficient of Variation (CV)
7%
Between run precision Coefficient of Variation (CV)
6%

Analytical measuring range

The technical data reported below refers to the measured values generated during the assay validation process using recombinant antigens. Per default, Olink Target 48 products deliver data in absolute protein concentrations (pg/mL) using the Calibrator built into the system.

Sensitivity plot

The calibrator curve shown below visualizes the analytical measuring range determined during the validation process using recombinant antigen. Please note that this is shown for reference only and CANNOT be used to e.g. convert NPX values to absolute concentrations. The vertical dotted lines represent lower limit of quantification (LLOQ) and upper limit of quantification (ULOQ) respectively. The solid horizontal line indicates the limit of detection (LOD).

Sample distribution plot

The plot below shows the levels of protein measured in a number of human samples (for further information please see the Validation Data Document which can be found in the Document download center). The data is shown to give an idea of the data range to expect but cannot cover protein levels that may be seen under all potential conditions.

Plasma

Human EDTA plasma samples were acquired for assay performance evaluation. Protein values indicate range, and group comparisons should be interpreted with caution.

Cerebrospinal fluid (CSF)

Human CSF samples were acquired for assay performance evaluation. Protein values indicate range, and group comparisons should be interpreted with caution.
