Buffer
PBS containing 0.02 % sodium azide.
Preservative
Sodium azide
Precaution of Use
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice
Avoid freezing and thawing repeatly.

4 °C/-20 °C
Storage Comment
Store at 4 °C for short term use.Store at -20 °C for long term preservation.
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 highand 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.
