Catalase activity is determined by measuring residual hydrogen peroxide after incubation with the enzyme. Ferrous ions and thiocyanate are used for the spectrophotometric determination of hydrogen peroxide. The stable visible absorption of ferrithiocyanate can be measured either with a plate reader or a ...

Catalase activity was determined in human semen by measuring the oxygen burst with a Clark electrode, after H2O2 addition. Significant catalase activities ... C Jeulin,JC Soufir,P Weber,... - 《Gamete Research》 被引量: 741发表: 1989年 Liquid storage of ram semen in the absence or presence...
aLiver samples were weighed, homogenized in 10 volumes of 0.1M 肝脏样品在10容量被称了,均匀的0.1M中[translate] acatalase analyses. GST activity was determined as described by Keen et al. 过氧化氢酶分析。 GST活动被确定了如所描述由敏锐等。[translate]...
It can not only regulate the H2O2 level in the body, but also act as a protective agent for Hb and other sulfhydryl protein. The changes in serum CAT activity are seen in the following diseases:The increase of CAT is mainly seen in liver cirrhosis, typhoid, fever etc.. The decrease of...
However, using this assay method, the hemoglobin content in lysate samples should be adjusted to uniform concentrations. Nomral activity levels of erythrocyte catalase were determined for 122 normal healthy Japanese adults -69 males and 53 females. The mean±standard deviation was 7.90±1.33 (K(0)...
The catalase activity of milk was determined by a disc flotation method designed for measuring the activity of catalase preparations. The method consists of absorbing milk on a 0.5-in. disc of highly absorbent paper and dropping the disc... RE Willits,FJ Babel - 《Journal of Dairy Science》 ...
(A) Aconitase activity was monitored in cell-free lysates after whole cells had been exposed to 1 µM Hg(II) or not exposed to Hg(II) for 30 min. (B) Cell-free lysates from the WT strain were exposed to 0 to 100 µM Hg(II) before aconitase activity was determined. (C)...
Catalase activity was determined in cell homogenates as described in Materials and Methods, using H2O2 as the substrate. Under the conditions used, none of the oxidants used was cytotoxic for RFASMC, except for H2O2 used at 50 μm (MTT viability test, data not shown). As seen in Fig. 1A...
