                                    Ephrin-A4 is a glycoinositol phospholipid membrane anchor containing ephrin found in variety of adult tissue such as kidney, lung, colon and ovary. Ephrin-A4 is a ligand for the erythropoietin-producing hepatocellular (Eph) receptor family of tyrosine kinases. Based on their structures and sequence relationships, ephrins are divided into the ephrin-A (EFNA) class, which are anchored to the membrane by a glycosylphosphatidylinositol linkage, and the ephrin-B (EFNB) class, which are transmembrane proteins. Ephrin-A4 encodes an EFNA class ephrin. Ephrin-A4 (s) may play a role in the interaction between activated B lymphocytes and dendritic cells in human tonsils. |

                                    This lyophilized protein is stable for six to twelve months when stored desiccated at -20℃ to -70℃. After aseptic reconstitution, this protein may be stored at 2℃ to 8℃ for one month or at -20℃ to -70℃ in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions. |
