  • 产品概述

    ab118184, is used to determine the relative specific activity (activity and quantity) of catalase in a sample. The native enzyme is immunocaptured within the wells of the microplate; this removes all other enzymes. The assay buffer contains hydrogen peroxide which reacts with a substrate to make a luminescent product. Catalase functions rapidly to remove hydrogen peroxide from the solution and reduce the production of light. Therefore the light produced in each well is inversely proportional to the amount of catalase activity.

    After activity measurement the quantity of catalase is measured by adding to each well an anti-catalase detector antibody. After washing away unbound detector antibody, HRP-conjugated label specific for the detector antibody is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of catalase bound. The developing blue color is measured at 600 nm. Optionally the reaction can be stopped by adding hydrochloric acid which changes the color from blue to yellow and the intensity can be measured at 450 nm.

  • 平台


  • 功能
    Occurs in almost all aerobically respiring organisms and serves to protect cells from the toxic effects of hydrogen peroxide. Promotes growth of cells including T-cells, B-cells, myeloid leukemia cells, melanoma cells, mastocytoma cells and normal and transformed fibroblast cells.
  • 疾病相关
    Defects in CAT are the cause of acatalasia (ACATLAS) [MIM:115500]; also known as acatalasemia. This disease is characterized by absence of catalase activity in red cells and is often associated with ulcerating oral lesions.
  • 序列相似性
    Belongs to the catalase family.
