The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
生物活性Specific activity is > 1,200 units/mg, in which one unit will inhibit the rate of reduction of cytochrome c by 50% in a coupled system, using xanthine and Xanthine oxidase at pH 7.8 at 25°C in a 1.5 ml reaction volume.
Prepare a 1.5 ml reaction mix into a suitable container and pre-chill on ice before use: The final concentrations are 50mM potassium phosphate, 0.1mM ethylendiaminetetraacetic acid, 0.01mM cytochrome C, 0.05mM xanthine, 0.005 units xanthine oxidase.
Equilibrate to 25°C and monitor at A550nm until the value is constant using a spectrophotometer.
Add 50 ul of recombinant SOD protein in various concentrations (0.5 ug, 1 ug) in assay buffer.
Mix by inversion and record the increase at A550nm for 5 minutes.
% SDS-PAGE. ab93946 was purified using conventional chromatography techniques.

功能Destroys superoxide anion radicals which are normally produced within the cells and which are toxic to biological systems.
疾病相关Genetic variation in SOD2 is associated with susceptibility to microvascular complications of diabetes type 6 (MVCD6) [MIM:612634]. These are pathological conditions that develop in numerous tissues and organs as a consequence of diabetes mellitus. They include diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease, and diabetic neuropathy. Diabetic retinopathy remains the major cause of new-onset blindness among diabetic adults. It is characterized by vascular permeability and increased tissue ischemia and angiogenesis.
序列相似性Belongs to the iron/manganese superoxide dismutase family.
翻译后修饰Nitrated under oxidative stress. Nitration coupled with oxidation inhibits the catalytic activity.
