Antigen: human S1P₁ amino acids 241-253 (ISKASRSSEKSLA) · Host: rabbit · Application(s): WB, IHC (formalin-fixed paraffin-embedded sections), and ICC; other applications not tested · Sphingosine-1-phosphate (S1P) exerts its activity by binding to five distinct G-protein-coupled receptors, S1P₁/EDG-1, S1P₂/EDG-5, S1P₃/EDG-3, S1P₄/EDG-6, and S1P₅/EDG-8.^1,2 S1P₁ primarily couples with pertussis toxin-sensitive G_i/o proteins to mediate S1P-induced cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis.^1,2,3 Expression of S1P₁ is abundant in embryological vasculature and is ubiquitously expressed in adult cells suggesting diverse physiological functions of this receptor.² The human and murine S1P₁ receptors have 382 amino acids with an estimated molecular weight of 43 kDa. Glycosylation at the N-terminal extracellular domain may cause the protein to migrate at a higher position in SDS-PAGE.⁴ Cayman’s S1P₁ polyclonal antibody detects the receptor at 47 kDa by western blot analysis. The antibody can also be used for immunocytochemistry and immunohistochemistry to study expression patterns of this protein.
