General description

Uricase deficient mice develop uric acid nephropathy and diabetes insipidus which can be mitigated with recombinant uricase treatment. [1]
Uricase is a homo-tetrameric protein with its active sites at the head-to-tail monomer-dimer interface.

Application

Uricase from Candida sp. has been used:
  • to eliminate urate in plasma samples and evaluate the contribution of urate to the total plasma antioxidant capacity
  • to intraperitoneally inject the mice to study the role of uric acid in fibrin extracellular traps (ET) formation
  • for elimination of uric acid in ferric reducing/antioxidative power (FRAP) assay to measure the total antioxidative capacity of human plasma sample; in uricase-based biosensors

Biochem/physiol Actions

Uricase participates in purine catabolism. It catalyzes the conversion of highly insoluble uric acid into 5-hydroxyisourate. Accumulation of uric acid causes liver/kidney damage or chronically causes gout. In mice, a mutation in the gene encoding uricase causes a sudden increase in uric acid. Mice, deficient in this gene, exhibit hyperuricemia, hyperuricosuria, and uric acid crystalline obstructive nephropathy.

Physical form

Powder; contains citrate and sucrose

Other Notes

One unit will oxidize 1.0 μmole of uric acid to allantoin per minute at pH 8.5 at 25 °C.

Questions

1–2 of 2 Questions  

  1. How can a solution in unit/mL be prepared using product number U0880, with a pack size of 250 units and SKU U0880-250UN, considering that the uricase activity is greater than 2 units/mg solid? What is the procedure for preparing a 10 unit/mL solution from this?

    1 answer

    1. You can use the calculator provided at https://www.physiologyweb.com/calculators/units_per_volume_solution_concentration_calculator.html

      Based on a specific activity of 5 units/mg, the 250 unit pack size is equivalent to 50 mg in mass. To achieve a 10 units/mL solution from this, the 50 mg would need to be dissolved in 25 mL of solvent (e.g. PBS).
