【H2O2過氧化氫檢測 】CheKine™ Hydrogen Peroxide (H2O2) Assay Kit 貨號KTB1041
過氧化氫 (Hydrogen Peroxide , H2O2)，一種活性氧代謝(reactive oxygen metabolic) 副產物，既是細胞內信號(intracellular signaling messenger)的信使，也是氧化應激(oxidative stress)的來源。過氧化氫(Hydrogen peroxide)通過多種機制在細胞中產生，例如中性粒細胞(neutrophils)和巨噬細胞(macrophages)產生 NOX 介導的 ROS（NOX-mediated ROS production），或由線粒體呼吸(mitochondrial respiration)過程中electron leak產生的超氧陰離子歧化酶(dismutase of superoxide anions)產生。通過 NF-κB 和其他因素起作用，氫過氧化物介導的通路與哮喘(asthma)、炎性關節炎(inflammatory arthritis)、動脈粥樣硬化(atherosclerosis)、糖尿病血管病變(diabetic vasculopathy)、骨質疏鬆症(osteoporosis)、神經退行性疾病(neurodegenerative diseases)、唐氏綜合症(Down’s syndrome)和免疫系統疾病(immune system diseases)有關。

CheKine™ 過氧化氫檢測試劑盒(CheKine™ Hydrogen Peroxide Assay Kit, KTB1041) 提供了一種簡單易用的比色檢測方法，用於測量血清(serum)、血漿(plasma)、細胞培養上清液(cell culture supernatants)、組織(tissue)/細胞裂解液(cell lysates)和其他生物液體(other biological fluids)中的過氧化氫(hydrogen peroxide)。在該測定中，H2O2 將亞鐵氧化(H2O2 oxidize ferrous)為三價鐵離子(ferric ion)，二甲苯酚橙(xylenol orange)以高選擇性結合三價鐵離子(ferric ion)，形成有色（紫色）產物，可通過比色法在 OD 580 nm 處進行測量。樣品中存在的過氧化氫與獲得的信號成正比。

| Product name | CheKine™ Hydrogen Peroxide (H2O2) Assay Kit |
| Applications notes | CheKine™ Hydrogen Peroxide Assay Kit provides a simple and easy colorimetric assay for measuring hydrogen peroxide in serum, plasma, cell culture supernatants, tissue/cell lysates and other biological fluids. In the assay, H2O2 oxidize ferrous to ferric ion, and xylenol orange binds ferric ion with high selectivity to form a colored (purple) product that can be measured by colorimetric method at OD 580 nm. The Hydrogen Peroxide present in the sample is proportional to the signal obtained. |

| Product name | PurKine™ His-Tag Cu-IDA Resin |
| Applications notes | PurKine™ His-Tag Cu-IDA Resin effectively purifies high levels of overexpressed His-tagged fusion proteins in gravity column procedures at a variety of scales. The Resin consists of 90μm beads of highly cross-linked 4% agarose, to which Iminodiacetic Acid (IDA) has been coupled. The chelating group has then been charged with copper ions (Cu2+). Tests confirm that performance equals or exceeds popular Cu-IDA resins from other suppliers, and no decrease in performance occurs after at least five repeated uses. |
| Alternative | Ni-NTA; His resin; Ni-NTA resin; His tag resin |
