IFN-α（Interferon-alpha，IFN-Alpha）是指干擾素α，它是一種類型的細胞因子，屬于干擾素家族。干擾素是哺乳動物細胞因子家族，具有調節(jié)免疫反應和抗病毒能力的作用。它們由大多數細胞類型合成和分泌，以響應病原體。除了抗病毒特性外，干擾素還被證明具有抗增殖、免疫調節(jié)和許多其他活性。  

  在人類中，IFN-α由一組氨基酸序列同源性大于85%的蛋白質組成。已鑒定出許多個人類IFN-α亞型；許多顯示不同的屬性。目前尚不清楚為什么有多種IFN-α亞型。各種研究表明，它們具有重疊但又獨特的生物活性。 我們推薦高靈敏度的人IFN-α全亞型ELISA試劑盒旨在對自身免疫血清、正常血清、EDTA 血漿和組織培養(yǎng)基（TCM）中的所有人IFN-α亞型進行準確的低 pg/ml 測量。提供了一種可靠且靈敏的方法，因此對于免疫學、炎癥和治療藥物監(jiān)測方面的研究非常有價值。作為PBL Assay Science在中國區(qū)域的代理商，艾美捷科技將為中國客戶提供全面的PBL Assay Science產品以及客戶訂制化服務。歡迎大家隨時聯系我們。
