The extrapure grade ensures minimal interference from impurities, making it ideal for sensitive applications. Each pack comes in convenient sizes (5g, 25g, or 100g) to match your lab’s consumption needs.
Remember, proper handling is crucial for this chemical. Always store in a cool, dry place away from direct sunlight, and follow standard lab safety protocols when using DTNB.
FAQs
1. What is DTNB used for in laboratories?
DTNB, or Ellman’s Reagent, is primarily used to quantify thiol groups (-SH) in proteins and other biomolecules. It’s essential for protein assays, enzyme activity studies, and research involving sulfur-containing compounds.
2. How do I prepare a DTNB solution for my assay?
Dissolve DTNB in a suitable buffer (typically 0.1 M phosphate buffer, pH 8.0) to make a 4 mg/mL stock solution. Filter if necessary and store protected from light. Always prepare fresh solutions for best results.
3. What’s the difference between regular and extrapure DTNB?
Extrapure DTNB undergoes additional purification steps to remove trace impurities, making it ideal for sensitive applications where background interference could affect results. It’s the preferred choice for research and diagnostic use.
4. How should I store DTNB to maintain its stability?
Store DTNB in its original container, tightly sealed, at 2-8?C. Protect from light and moisture. Properly stored, it maintains stability for at least 2 years from manufacture date.
5. Can I buy DTNB in bulk quantities from eqipped?
Yes, eqipped offers DTNB in 5g, 25g, and 100g pack sizes. For larger research needs, contact our customer support for bulk pricing and availability.
