Uniprot Function Description

Participates in the induction of key genes involved in the response to hypoxia and in the induction of angiogenesis such as HIF1A (PubMed:35455969). Involved in protecting cells from hypoxia-mediated cell death (PubMed:35455969).

Growth factor active in angiogenesis, vasculogenesis and endothelial cell growth. Induces endothelial cell proliferation, promotes cell migration, inhibits apoptosis and induces permeabilization of blood vessels. Binds to the FLT1/VEGFR1 and KDR/VEGFR2 receptors, heparan sulfate and heparin. Binds to the NRP1/neuropilin-1 receptor. Binding to NRP1 receptor initiates a signaling pathway needed for motor neuron axon guidance and cell body migration, including for the caudal migration of facial motor neurons from rhombomere 4 to rhombomere 6 during embryonic development (PubMed:26503042). Also binds the DEAR/FBXW7-AS1 receptor (PubMed:16293765). May play a role in increasing vascular permeability during lactation, when increased transport of molecules from the blood is required for efficient milk protein synthesis (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)

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 mouse 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

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