An antibody specific for EFNA1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyEFNA1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for EFNA1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of EFNA1 bound in the initial step. The color development is stopped and the intensity of the color is measured.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eProduct Overview\u003c\/b\u003e: Ephrin-A1 is a member of the ephrin (EPH) family. The ephrins and EPH-related receptors comprise the largest subfamily of receptor protein-tyrosine kinases and have been implicated in mediating developmental events, especially in the nervous system and in erythropoiesis. 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. This gene encodes an EFNA class ephrin which binds to the EPHA2, EPHA4, EPHA5, EPHA6, and EPHA7 receptors. Two transcript variants that encode different isoforms were identified through sequence analysis.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eStability\u003c\/b\u003e: The stability of ELISA kit is determined by the loss rate of activity. The loss rate of this kit is less than 5% within the expiration date under appropriate storage condition. \nThe loss rate was determined by accelerated thermal degradation test. Keep the kit at 37°C for 4 and 7 days, and compare O.D.values of the kit kept at 37°C with that of at recommended temperature. (referring from China Biological Products Standard, which was calculated by the Arrhenius equation. For ELISA kit, 4 days storage at 37°C can be considered as 6 months at 2 - 8°C, which means 7 days at 37°C equaling 12 months at 2 - 8°C).\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":40500607516772,"sku":"AE46076HU","price":131700.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/products\/no_image_default_image-jpeg_6564cfc9-983d-44e8-aca6-8646177466c7.jpg?v=1660527228","url":"https:\/\/www.genebiosystems.com\/en-jp\/products\/human-ephrin-a1-efna1-elisa-kit","provider":"GeneBio ","version":"1.0","type":"link"}
