特點

Hydrogen Peroxide分析套組 |貨號K265-200 呈色100個分析/螢光200個分析(Abcam ab102500)

Biovision提供一系列Oxidative Stress分析套組;其中Hydrogen Peroxide分析套組分析套組,一組產品可選擇呈色Absorbance (570 nm)或螢光Fluorescence (Ex/Em 535/587 nm)兩種型態偵測Absorbance (570 nm) or Fluorescence (Ex/Em 535/587 nm);可用於細胞組織Lysates、細胞培養液、food、尿液、血漿、或液體型式的來源。操作時間大約60分鐘。測量最低靈敏度2 pmol per assay (or 40 nM concentration) of H₂O₂ in the sensitive fluorometric assay.

過氧化氫(Hydrogen Peroxide) 是活性氧(reactive oxygen) 代謝副產物,其用作許多氧化應激 (oxidative stress) 相關狀態的關鍵調節劑。 通過NF-κB和其他因子的功能,氫過氧化物介導的途徑已經與哮喘(asthma),炎症性關節炎(inflammatory arthritis),動脈粥樣硬化(atherosclerosis),糖尿病血管病變 (diabetic vasculopathy) ,骨質疏鬆症(osteoporosis),神經變性疾病 (neuro-degenerative diseases),唐氏綜合徵 (Down’s syndrome) 和免疫系統疾病(immune system diseases)相關。 BioVision的過氧化氫測定試劑盒 (Hydrogen Peroxide Assay Kit, K265) 是一種用於測量生物樣品中H 2 O 2的方法,具有高靈敏度,簡單,直接和HTS比色和螢光測定法。 在辣根過氧化物酶(Horse Radish Peroxidase, HRP)存在下,OxiRed探針與H 2 O 2反應產生具有顏色(λmax = 570nm)和紅色螢光(Ex / Em = 535 / 587nm)的產物。 試劑盒可以通過螢光法進行200個反應或通過比色法進行100個反應。 在靈敏螢光測定中,檢測極限可以低至每個試驗(或40nM濃度)H 2 O 2 2pmol。

組織樣品的製備,50 mg組織開始,於300-400 µl分析緩衝液中勻漿。均質化可以在冰上使用杜恩斯均質器或輕度超聲(很少有短脈衝)進行。在均質過程中,樣品應保存在冰上。勻漿後,組織裂解液應以10,000xg離心2分鐘,收集上清液並通過10 kDa MW旋轉柱過濾(BV Cat。#1997)。大多數Reader在其檢測帶寬上具有靈活性。對於建議的570 nm波長,您的540 nm波長應該可以正常工作,只要它具有+/- 30 nm即可。
