The following standard curve is provided for demonstration only. A standard curve should be generated for each set of sample assay.
Autotaxin, also known as ENPP-2, is a secreted glycoprotein which belongs to the ectonucleotide pyrophosphatase/phosphodiesterase (NPP) family. Generally, NPPs can hydrolyze phosphates from nucleotides. Autotaxin exhibits the unique lysophospholipase D activity. The mature protein includes two somatomedin-B-like (SMB) cysteine knot domains, a catalytic domain, and an inactive C-terminal nuclease-like domain with an ef-hand-like motif that is important in cell motility, and a region involved in autotaxin secretion. There are three isoforms identified in mouse and human. Most circulating autotaxin is the β form which contains 863 amino acid. Autotaxin contributes to the predominant extracellular source of the phospholipid LPA (lysophosphatidic acid) from LPC (lysophosphatidylcholine). Autotaxin can also produce minor amounts of sphingosine 1-phosphate and cyclic phosphatidic acid which can antagonize many of the tumorigenic properties of LPA. Autotaxin stimulates tumor cell motility and enhances invasion and metastasis. It’s upregulated in melanoma, glioblastoma, breast and lung carcinoma, follicular lymphoma and other cancers. Autotaxin production by adipocytes enhances pre-adipocyte proliferation and may be
elevated in obesity. Autotaxin is present in blood, urine, saliva, seminal and cerebrospinal fluids. In addition, plasma autotaxin is cleared by the liver which is elevated in liver disease. Normal serum or plasma autotaxin concentration is reported to be slightly higher in females than in males and highest in pregnant females.
The lowest level of CRP that can be detected by this assay is 0.78 ng/ml.
Intra-assay Precision (Precision within an assay) C.V <10%.
Inter-assay Precision (Precision between assays) C.V <10%.
Serum samples were assayed by adding 90 µl of the sample and 10 µl of spike stock solution calculated to yield the intended 0, 5, 10 ng/ml spike concentration. The recovery of human autotaxin spiked to different levels falls in 90-110%.
The recovery of the assay was determined by adding various amounts CRP to a sample. The measured concentration of the spiked sample in the assay was compared to the expected concentration. The average recovery was 98%.
