<h3>Overview</h3>
<p><strong>J&K Xanthine oxidase, microbial, 40 units/mg</strong> is a lyophilized enzyme preparation derived from <em>Aspergillus flavus</em>. It catalyzes the oxidation of hypoxanthine to xanthine and xanthine to uric acid. The product typically exhibits a specific activity of ≥40 U/mg protein with high purity.</p>
<h3>Application</h3>
<ul>
<li><strong>Diagnostics:</strong> Quantitative analysis of uric acid levels in serum for gout monitoring.</li>
<li><strong>Research:</strong> Study of oxidative stress mechanisms and purine metabolism pathways.</li>
<li><strong>Pharmaceuticals:</strong> Screening assay for xanthine oxidase inhibitors used in anti-hyperuricemic drugs.</li>
</ul>
<h3>Precautions</h3>
<p>Store at -20°C to maintain stability; avoid repeated freeze-thaw cycles. Use appropriate PPE as biological reagents may cause sensitization. Not intended for direct clinical administration or therapeutic use in humans.</p>
