  • Function
    Receptor for the lysosphingolipid sphingosine 1-phosphate (S1P). S1P is a bioactive lysophospholipid that elicits diverse physiological effect on most types of cells and tissues. This inducible epithelial cell G-protein-coupled receptor may be involved in the processes that regulate the differentiation of endothelial cells. Seems to be coupled to the G(i) subclass of heteromeric G proteins.
  • Tissue specificity
    Endothelial cells, and to a lesser extent, in vascular smooth muscle cells, fibroblasts, melanocytes, and cells of epithelioid origin.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Post-translational
    S1P-induced endothelial cell migration requires the PKB/AKT1-mediated phosphorylation of the third intracellular loop at the Thr-236 residue.
  • Cellular localization
    Cell membrane.

Thank you for your inquiry. I heard back from the testing laboratory regarding the fixation/permeabilization protocol for ab11424. Aspirate culture medium and add warmed Fixation Solution (4% Formaldehyde, 37C) and incubate 15 minutes at room temperature. Aspirate Fixation Solution and wash with Dulbecco’s PBS. Aspirate solution. Add Permeabilization Solution (Dulbecco’s PBS with 0.1% Trition X100) and incubate 15 minutes at room temperature. Aspirate solution and proceed to blocking/antibody steps. I hope this information helps. I hope to have the ICC/IF image on the datasheet shortly. Please contact us with any other questions.

Thank you for your email. When ab11424 was tested in IF, transfected CCL39 cells were used. So to our knowledge it has not yet been tested in IHC. Ab13126 has only been tested for cross-reactivity with human and we don't have any information about how it will work with other species. Neither antibody has been tested yet for application in Flow Cytometry. If you have any more questions, please contact us again.

Thank you very much for your patience, I have just heard back from the originator of ab11424. By Western blot, this antibody detects an ~44 kDa protein representing recombinant S1P1 from transfected HEK293 cells. The figure on the website shows a Western blot of S1P1 in transfected HEK293 cell lysate using ab11424; the band is at approximately 44 kDa. It is recommended to use transfected HEK293 cells as a positive control. If you need further assistance with this antibody, please do let me know.

HEK293 cells were transiently transfected with the myc-tagged receptor. After 48 hrs, cells were solubilized (in buffer containing: 1% triton X-100, 0.5% deoxycholate, 0.1% SDS.) and protein-equalized. Samples were fractionated by SDS-PAGE (12% gel). After transfer to nitrocellulose, membrane was incubated overnight at 4 deg. C with ab11424 followed by HRP-conjugated anti-rabbit IgG.
