The Alkaline Protease (AKP) Activity Assay Kit can be used to detect the activity of enzymes that catalyze the hydrolysis of protein peptide bonds under alkaline conditions. This type of enzyme belongs to serine protease, which has the functions of transesterification and transpeptide.
Under alkaline conditions, AKP hydrolyzes casein to produce tyrosine;Under alkaline conditions, tyrosine reduces phosphomolybdenum acid to produce tungsten blue;Tungsten blue has a characteristic absorption peak at 680 nm, and the rate of increase in absorbance at 680 nm is measured to calculate AKP activity.
Tyrosinase is a multi-subunit-containing copper-containing oxidoreductase, which is widely found in microorganisms, animals and plants and human bodies, with a variety of characteristic catalytic activities and physiological functions, as a key enzyme for the synthesis of melanin by organisms, it is also the main factor causing enzymatic browning of fruits and vegetables, and also has an important impact on the immunity and growth of insects, and has a wide range of applications in antioxidant, biological detection, environmental protection, etc.
Tyrosinase can catalyze the generation of dopa pigment from L-dopa, and the product has a characteristic absorption peak at 475 nm, and tyrosinase activity can be characterized by the change of absorbance value.
The use of this type of kit can meet the needs of the detection of alkaline protease activity, but the actual operation involves multiple factors such as the use of reagents, instruments, and personnel skills, and the specific results need to be judged in combination with the actual application scenarios.
An enzyme activity assay kit is a tool used to quantitatively detect the activity of a specific enzyme and is commonly used in research in fields such as biochemistry and molecular biology. The following is an example of an enzyme activity assay kit and a superoxide dismutase (SOD) activity assay kit.
Enzyme Activity Assay Kit:
The Enzyme Activity Assay Kit provides a powerful and convenient method to measure Enzyme activity in live cells. These assays utilize substrates containing permeable cells with recognition sites to measure the activity of S3 and 7, S8, or S9, as well as multiplex assay kits that can measure four Ss simultaneously.
SOD Enzyme Activity Assay Kit:
Superoxide dismutase (SOD, EC1.)15.1.1) It is an enzyme that catalyzes the disproportionation of superoxide anions into O2 and H2O2. They are important antioxidants against superoxide radical toxicity in all cells exposed to O2. Abnormal SOD activity has been linked to diseases such as amyotrophic lateral sclerosis, perinatal death, neurological disorders, and cancer.
The above is a brief introduction to the enzyme activity assay kit, for more information, please consult the literature or contact a professional.
