Uniprot Function Description

Binds directly to activin and functions as an activin antagonist. Specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (FSH).

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.

Precision

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

Within run precision Coefficient of Variation (CV)
5%
Between run precision Coefficient of Variation (CV)
11%

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.

LOD (pg/mL)
31.0
LLOQ (pg/mL)
31.0
ULOQ (pg/mL)
62500
Hook (pg/mL)
125000
Range (logs)
3.3

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).
