【DNA Damege損傷/細胞Stress 】Abbkine促銷優惠活動DM&產品資料

氧化應激(Oxidative stress)與包括心血管疾病(chronic diseases)在內的許多慢性疾病的病因有關。脂質過氧化(Lipid peroxidation)是由於氧化損傷(oxidative damage)而發生的脂質(lipids)降解(degradation)，是氧化應激(oxidative stress)的有用標記(useful marker)。多不飽和脂質(Polyunsaturated lipids)通常易受活性氧(reactive oxygen)的影響而受到氧化攻擊，從而導致產生明確的鏈反應，並生成最終產物，如丙二醛（malondialdehyde ,MDA）脂質過氧化(Lipid peroxidation)可能導致許多疾病的病理，包括動脈粥樣硬化(atherosclerosis)，糖尿病(diabetes)和阿爾茨海默氏病(Alzheimer’s)。

CheKine™脂質過氧化（CheKine™ Lipid Peroxidation (MDA) Assay Kit, MDA）檢測試劑盒為檢測各種樣品中存在的丙二醛（malondialdehyde, MDA）提供了便利的工具。 MDA與4-羥基壬烯醛（4-hydroxynonenal , 4-HNE）一起是脂質過氧化(lipid peroxidation)作用的天然副產物，其定量通常用作脂質過氧化(lipid peroxidation)作用的標記。樣品中的MDA與硫代巴比妥酸（thiobarbituric acid ,TBA）反應生成MDA-TBA加合物，可以很容易地在OD 532 nm處進行比色定量。同時，測量600nm處的吸光度，並通過532nm和600nm處的吸光度之差計算MDA（以避免蔗糖(saccharose) 的干擾）。1-100 µM/L

CheKine™ Lipid Peroxidation (MDA) Assay Kit provides a convenient tool for detection of the malondialdehyde (MDA) present in a variety of samples. MDA, together with 4-hydroxynonenal (4-HNE), is a natural bi-product of lipid peroxidation and its quantification is generally used as marker for lipid peroxidation. The MDA in the sample reacts with thiobarbituric acid (TBA) to generate a MDA-TBA adduct，which can be easily quantified colorimetrically at OD 532 nm. Meanwhile, the absorbance at 600 nm was measured , and MDA was calculated by the difference between the absorbance at 532 nm and 600 nm (To avoid the interference of saccharose).

活性氧物種(Reactive Oxygen Species, Ros ) Ros是氧正常代謝的天然副產物，在細胞信號傳導(cell signaling)和體內平衡(vivo balance)中起重要作用。但是，在氧化應激相關狀態(oxidative stress correlation state)下，ROS水平可以大大提高。 ROS的積累將嚴重破壞細胞結構(cell structure)。氧化應激(Oxidative stress)在心血管疾病(cardiovascular disease)，糖尿病(diabetes)，骨質疏鬆(osteoporosis)，中風(stroke)，炎性疾病(inflammatory disease)以及神經退行性疾病(neurodegenerative diseases)和癌症(cancer)等研究中起著重要作用。 ROS檢測將有助於確定氧化應激(oxidative stress)如何調節各種細胞內途徑(intracellular pathways)。Reactive Oxygen Species, Ros is natural by-products of oxygen normal metabolism, play an important role in cell signaling and in vivo balance. However, in the oxidative stress correlation state, the ROS level can be greatly increased. The accumulation of ROS will seriously damage the cell structure.

Background	The superoxide anion (O2－) is a short-lived radical production by the addition of an electron to oxygen. It is formed in response to environmental factors such as UV light, cigarette smoke, environmental pollutants, and g-radiation, or derived from oxidases like xanthine oxidase or NADPH oxidase. Once formed, O2－ attacks cellular components and causes damage to lipids, proteins and DNA. This can initiate numerous diseases, including cancer, atherosclerosis, rheumatoid arthritis, diabetes, liver damage, and central nervous system disorders. The study of scavenging superoxide anion radicals has been gained more and more attention.
