This strain was extracted from the fermentation broth of Aspergillus niger or Aspergillus flavus, and the relative molecular mass was 9300. This product is gray-white or brown-green crystal or bright transparent flakes. Practically insoluble in water, slightly soluble in alkaline buffer, isoelectric point pl = 6.3. Cyanide inhibits enzyme activity. It can catalyze the rapid oxidation of uric acid, and eventually produce allantoic acid. Refined uricase injection into the human body, can reduce the uric acid content in the blood, increase allantoic acid excretion in urine, thereby eliminating uric acid retention in the blood and tissues.
visible generalized urticaria itching, local Red intramuscular injection.
uricase | fecal acid enzyme is a new type of uric acid lowering drug, also known as Uricase acid, urate oxidase and Urate Oxidase, which is characterized by promoting uric acid decomposition. Catalytic uric acid is rapidly oxidized to become allantoic acid, which is no longer reabsorbed by renal tubules and excreted, thereby reducing the content of uric acid in plasma. For patients who cannot take oral uric acid suppressants. It has a good effect on hyperuricemia caused by uric acid stones, nodular gout, leukemia, renal failure and other factors. |
chemical properties | slightly green crystals or shiny locust stripes. Almost insoluble in water, slightly soluble in buffer alkaline solution is quite stable in ph7.5 ~ 10.5 solution, has significant absorption effect in 330~350nm region, can be passivated by cyanide ions, and trace amount (10-4mol · L-1) potassium cyanide can inhibit enzyme activity. There are also freeze-dried powder (sodium carbonate as stabilizer), ammonium sulfate suspension and glycerin solution. |
use | commonly used diagnostic enzymes. Determination of uric acid in serum and urine. It is used for biochemical research and clinically commonly used as a diagnostic enzyme to detect uric acid in serum and urine. uricase is used to determine the amount of uric acid in serum and urine in temporary entertainment. It is also used clinically for the treatment of urinary stones, nodular gout, and hyperuricemia caused by renal insufficiency. But local redness after intramuscular injection, sometimes systemic nettle-like itching can be seen. Intramuscular or intravenous injection, once a day, each dose as prescribed by the doctor. |
production method | yeast is used as raw material, sodium phosphate is extracted and graded with ammonium sulfate, and then the product is obtained by dialysis, column chromatography and ammonium sulfate recrystallization. |
