生物感測器(biosensors)-葡萄糖氧化酶 (glucose oxidase enzyme , GOx) 

葡萄糖氧化酶 (glucose oxidase enzyme , GOx) (EC 1.1.3.4)是一種氧化還原酶，可催化葡萄糖有氧氧化成過氧化氫(H ₂ O ₂ )和葡萄糖酸。葡萄糖氧化酶 (glucose oxidase enzyme , GOx) (EC 1.1.3.4) 是一種二聚酶(dimeric enzyme)，可催化 β-D-葡萄糖(beta-D-glucose)氧化成過氧化氫(hydrogen peroxide)和 D-葡萄糖酸-1,5-內酯(D-glucono-1,5-lactone)，後者被水解成葡萄糖酸(gluconic acid)。 這種酶是由某些種類的昆蟲(insects)、真菌(fungi)和細菌(bacteria)產生的。葡萄糖氧化酶(Glucose oxidase)廣泛用於測定體液中的葡萄糖以及去除飲料、食品和其他農產品中殘留的葡萄糖和氧氣(oxygen)。 微生物葡萄糖氧化酶因其在化學、製藥、食品、飲料、臨床化學、生物技術等行業的廣泛應用而備受關注。近年來，葡萄糖氧化酶在生物感測器中的新應用增加了需求。此外，葡萄糖氧化酶(Glucose oxidase)通常用於生物傳感器(biosensors)以檢測葡萄糖。GOD廣泛應用於工業原料生產、生物感測器和癌症治療等領域。

葡萄糖氧化酶活性測定 | Glucose Oxidase Activity (GOD) Assay Kit貨號KTB1310

CheKine™ Glucose Oxidase Activity (GOD) Assay Kit 偵測範圍: 0.05 – 2 U/L, 最低靈敏度0.05 U/L

CheKine™ 葡萄糖氧化酶活性測定試劑盒(CheKine™ Glucose Oxidase Activity Assay Kit, KT1310)提供了一種簡單易行的比色測定法，用於檢測生物樣品中的葡萄糖氧化酶活性(Glucose Oxidase Activity)，例如血清或血漿、細胞、尿液、其他體液、食物、生長培養基中的葡萄糖氧化酶活性。 在該測定中，葡萄糖氧化酶 (glucose oxidase enzyme , GOx) 活性通過偶聯酶測定確定，其中葡萄糖氧化酶 (glucose oxidase enzyme , GOx) 氧化 D-葡萄糖(D-glucose)，導致產生過氧化氫 (hydrogen peroxide , H2O2)，該過氧化氫 (hydrogen peroxide , H2O2) 在酸性條件下與色原反應，產生可在 OD 580 下測量的產物。 因此，樣品中存在的葡萄糖氧化酶活性與獲得的信號成正比。偵測範圍: 0.05 – 2 U/L, 最低靈敏度0.05 U/L。可應用於以下樣品來源: serum or plasma, cells, urine, other body fluid, food, growth medium。(貨號KTB1310)
