Recommended Concentration

Sample

ELISA

This antibody functions as an ELISA capture antibody when paired with Sheep Anti-Human Sphingosine Kinase 1/SPHK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5536).

This product is intended for assay development on various assay platforms requiring antibody pairs. We recommend the Human Sphingosine Kinase 1/SPHK1 DuoSet ELISA Kit (Catalog # DY5536) for convenient development of a sandwich ELISA.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Human Sphingosine Kinase 1/SPHK1 ELISA Standard Curve. Recombinant Human Sphingosine Kinase 1/SPHK1 protein was serially diluted 2-fold and captured by Mouse Anti-Human Sphingosine Kinase 1/SPHK1 Monoclonal Antibody (Catalog # MAB5536) coated on a Clear Polystyrene Microplate (Catalog # DY990). Sheep Anti-Human Sphingosine Kinase 1/SPHK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF5536) was biotinylated and incubated with the protein captured on the plate. Detection of the standard curve was achieved by incubating Streptavidin-HRP (Catalog # DY998) followed by Substrate Solution (Catalog # DY999) and stopping the enzymatic reaction with Stop Solution (Catalog # DY994).

Background: Sphingosine Kinase 1/SPHK1

Sphingosine kinases are cytosolic or membrane-associated enzymes that catalyze the phosphorylation of sphingosine to sphingosine-1-phosphate (S1P). Two types of sphingosine kinases, SPHK1 and SPHK2, are known to be expressed in human cells. The two enzymes share considerable amino acid sequence similarity, but differ in their N‑terminal and central regions (1). The two proteins also differ in tissue distribution and some kinetic properties (1). S1P is a lipid messenger that regulates diverse physiological processes including cell proliferation, migration, apoptosis, inflammation, calcium homeostasis and cytoskeletal structure (2, 3). The level of S1P is tightly controlled by SPHKs and S1P degrading enzymes. SPHK1 and its activation can be stimulated by several growth factors such as tumor necrosis factor-alpha, epidermal growth factor and transforming growth factor-beta (3, 4). Expression of SPHK1 has been found to increase in many human solid tumors and overexpression of SPHK1 is associated with tumor angiogenesis (5). Such studies have implicated SPHK1 as a new target for cancer treatment.
