格隆匯 04-01 16:49

格隆匯 4 月 1日丨九強生物(300406.SZ)公佈,於近期收到中華人民共和國國家知識產權局頒發的1項專利證書,為一種表達大腸桿菌β半乳糖苷酶受體的宿主細胞。

申請涉及一種表達大腸桿菌β半乳糖苷酶受體的宿主細胞。本申請提供了一種SEQ ID NO1所示的編碼β半乳糖苷酶受體的核苷酸,以及SEQ ID NO2所示的β半乳糖苷酶受體。根據大腸桿菌β半乳糖苷酶結構和功能,以及酶供體和酶受體的互補原理,設計了刪除第1333位氨基酸的酶受體;將酶受體的編碼核苷酸與載體連接,並轉化至大腸桿菌構建重組表達宿主細胞;通過發酵大量表達酶受體;通過親和層析技術對酶受體純化,脱鹽後的酶受體純度在90以上。與常規酶受體相比,本申請的酶受體產量更高、互補活性更強,可應用於CEDIA生化診斷試劑的研製。

上述發明專利證書的取得不會對公司生產經營產生重大影響,但在一定程度上有利於發揮公司的知識產權優勢,促進技術創新,有利於提升公司的核心競爭力,有利於公司形成持續創新機制。
