S1P1/EDG-1 Antibody Summary

• Immunogen: Antibody was raised against a 14 amino acid synthetic peptide near the carboxy terminus of the human S1P1. The immunogen is located within the last 50 amino acids of S1P1.
• Specificity: At least two isoforms of S1P1 are known to exist; this S1P1 antibody will only recognize the shorter isoform.
• Isotype: IgG
• Clonality: Polyclonal
• Host: Rabbit
• Gene: S1PR1
• Purity: Immunogen affinity purified

Applications/Dilutions

• Dilutions:

Background

Movement of lymphocytes through lymphoid organs is required for generating immunity. Their migration into lymph nodes follows a series of events including integrin activation through chemokine signaling, adhesion and diapedis. The release of lymphocytes from lymph nodes is regulated by the phospholipid sphingosine-1-phosphate (S1P). One of its receptors S1P1 binds S1P with high specificity and affinity; agonism of this receptor by the immunosuppressive agent FTY720 inhibits the entry of tissue T cells into afferent lymphatics in homeostatic and inflammatory conditions. Recent experiments have indicated that CCR7-deficient T cells left lymph nodes more rapidly than wild-type cells did and these cells where also less effectively retained after treatment with FTY720, and that egress competence could be restored by inactivating G alpha i-protein-coupled receptor signaling. These results suggest that S1P1 acts in the lymphocyte to promote lymph node egress by overcoming retention signals mediated by CCR7 and G alpha i-protein-coupled receptor signaling. At least two isoforms of S1P1 are known to exist; this S1P1 antibody will only recognize the shorter isoform.
