OxiSelec總抗氧化能力(TAC)分析試劑盒

活性氧(Reactiveoxygenspecies,ROS)主要包括羥基自由基、超氧自由基和過氧化氫。在細胞或組織的正常生理代謝過程中會產生活性氧，同時一些環境因子例如紫外照射、吸煙、環境污染等也可以誘導活性氧的產生。活性氧在體內的失衡，將會導致細胞脂、蛋白和DNA的氧化損傷，繼而導致各種腫瘤、風濕性關節炎、糖尿病、肝損傷、以及中樞神經系統疾病等。

當然，機體中也存在許多種抗氧化的物質，包括抗氧化大分子、抗氧化小分子和酶等，能夠清除體內產生的各種活性氧，以阻止活性氧造成的氧化損傷。一個體系內的各種抗氧化大分子、抗氧化小分子和酶的總的水平即體現了該體系內的總抗氧化能力。因此測定樣本中的總抗氧化能力（TAC）具有非常重要的生物學意義。

FAQ常見問題：

1.總抗氧化能力（TAC）檢測試劑盒，有物種種屬限制嗎？

我們的總抗氧化能力（TAC）檢測試劑盒，適用于任何生物蛋白質樣品。因為試劑盒原理并不依賴于可能因物種而異的蛋白質結構。

2.是否可以檢測凍存過的樣本？

我們的總抗氧化能力（TAC）檢測試劑盒，通常適用于在 -80?C 下保存兩個月以內樣品，但我們建議盡可能測試新鮮樣品以獲得最佳結果。

3.在制備食品樣品時，1:2, w/v 是什么意思？

食品樣品應準備為 1 g 樣品：2 mL 去離子水。

4.檸檬酸鹽血漿樣品可以用于該測定嗎？

檸檬酸鹽血漿樣品與總抗氧化能力測定兼容。 但應避免使用EDTA，因為這會干擾檢測。

5.該試劑盒可以測量細胞培養上清液的總抗氧化能力嗎？

不幸的是，我們的總抗氧化能力測定與細胞培養上清液不兼容。該測定基于銅的還原，介質中存在的鐵會干擾該反應。
