Western Blot (WB)
(Western blot image of recombinant his-tagged human SK1 protein that was phosphorylated with ERK-2. Blots were probed with anti-SK1 (Central Region) (SP1621; lanes 1-3) and anti-SK1 (Ser-225) (SP1641; lanes 4-6). Both antibodies were used in the presence of no peptide (lanes 1 & 4), phospho-SK1 (Ser-225) peptide (SX1645; lanes 2 & 5), or unphosphorylated SK1 (Ser-225) peptide (SX1625; lanes 3 & 6).)

NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene catalyzes the phosphorylation of sphingosine to form sphingosine-1-phosphate (S1P), a lipid mediator with both intra- and extracellular functions. Intracellularly, S1P regulates proliferation and survival, and extracellularly, it is a ligand for cell surface G protein-coupled receptors. This protein, and its product S1P, play a key role in TNF-alpha signaling and the NF-kappa-B activation pathway important in inflammatory, antiapoptotic, and immune processes. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011]
Uniprot Description
SPHK1: Catalyzes the phosphorylation of sphingosine to form sphingosine 1-phosphate (SPP), a lipid mediator with both intra- and extracellular functions. Also acts on D-erythro-sphingosine and to a lesser extent sphinganine, but not other lipids, such as D,L-threo-dihydrosphingosine, N,N-dimethylsphingosine, diacylglycerol, ceramide, or phosphatidylinositol. Interacts with ACY1. Binds to calmodulin. Interacts with SPHKAP. Widely expressed with highest levels in adult liver, kidney, heart and skeletal muscle. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The SPHK1 sphk1 (Catalog #AAA474599) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Sphingosine Kinase 1 (Ser-225), phospho-specific Antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Sphingosine Kinase 1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). ELISA: 1:2000 WB: 1:1000. Researchers should empirically determine the suitability of the SPHK1 sphk1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Sphingosine Kinase 1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
