ROS 攻擊體內細胞膜上之多元性不飽和脂肪酸,形成脂質過氧化反應,並與膜上之接受器產生共價結合,進而導致細胞膜完整性遭受破壞。2. ROS 與蛋白質產生交錯連結反應,改變蛋白質結構或使蛋白變性,造成催化代謝反應之酵素失活。3. ROS 會攻擊 DNA 分子的鹼基結構,進一步產生基因突變或毒性。許多文獻指出,自由基在體內堆積以及造成細胞破壞,是形成老化相關現象與疾病的重要原因之一,例如:退化性疾病、癌症、心血管疾病、關節炎等等,其中有研究報導,現代成人病中約有 85% 與 ROS 及脂質過氧化有關。氧化壓力產品選擇指南

This product contains two enhanced bands (1.5kand 500 bp) for easy reference.The ladder is ready-to-use, which is premixed with loading buffer dye for direct loading on gel.10 mM Tris-HCl (pH 8.0), 10 mM Na-EDTA, 0.03% orange G,0.005% xylene cyanol FF, and 10% glycerol.DM1KThe DNA Ladder DM1K is composed of 13 individual DNA fragments: 10k, 8k, 6K, 5K, 4K, 3K, 2.5K, 2K, 1.5K, 1K, 750, 500, and 250 base pairs. This product contains two enhanced bands (3kand 1K bp) for easy reference.The ladder is ready-to-use, which is premixed with loading buffer dye for direct loading on gel.10 mM Tris-HCl (pH 8.0), 10 mM Na-EDTA, 0.005% bromophenol blue, 0.005% xylene cyanol FF, and 10% glycerol.DM100+3KThe DNA Ladder DM100+3K is composed of 12 individual DNA fragments:3k, 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200, and 100 base pairs. This product contains two enhanced bands (1.5kand 500 bp) for easy reference.Protein MarkerPMB1ANTEC 3-color Pre-Stained Protein Marker is a three-color protein standard with 10 pre-stained proteins covering a wide range molecular weights from 10 to 180 KDa. Proteins are covalently coupled with a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-glycine buffer). ANTEC 3-color Pre-Stained Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating size of proteins.The ladder is ready-to-use, which is premixed with loading buffer dye for direct loading on gel. Approximately 0.1~0.4 mg/ml of each protein in the buffer. 20 mM Tris-phosphate, pH 7.5 (at 25℃), 2 % SDS, 0.2 mM Dithiothreitol, 3.6 M Urea, and 15 % (v/v) Glycerol.
