The success of bioluminescent assays hinges significantly on the quality of the reagents used. For D-Luciferin Potassium Salt (CAS 115144-35-9), a critical substrate for luciferase enzymes, understanding the key quality indicators is essential for any discerning buyer. As a professional supplier, we aim to guide you through the crucial aspects to consider when you decide to buy D-Luciferin Potassium Salt.

The Importance of Purity:

The primary determinant of D-Luciferin Potassium Salt quality is its purity. High purity, typically exceeding 98% or 99%, ensures that the bioluminescent signal generated is solely due to the intended reaction between luciferin, luciferase, and ATP. Impurities can:

  • Increase background luminescence: Leading to lower signal-to-noise ratios and making it difficult to detect low-level signals.
  • Reduce signal intensity: Diluting the active component and weakening the light output.
  • Interfere with enzyme activity: Potentially inhibiting the luciferase enzyme itself.

When you are looking to purchase D-Luciferin Potassium Salt, always scrutinize the product's Certificate of Analysis (CoA). A reputable manufacturer will clearly state the assay method used (e.g., HPLC) and the purity of the compound. For sensitive applications, such as those requiring low ATP detection limits, opting for the highest purity available is advisable.

Stability and Storage Considerations:

D-Luciferin Potassium Salt is generally stable in its solid, dry form when stored correctly. However, like many organic compounds, it is susceptible to degradation over time, especially when exposed to light, moisture, or elevated temperatures. Recommended storage conditions are typically:

  • Temperature: -20°C
  • Protection: Shielded from light and moisture.

For long-term storage and to maintain activity, it is often recommended to aliquot the D-Luciferin Potassium Salt into smaller portions and store them frozen. Diluted solutions in aqueous buffers are less stable and should be prepared fresh for each assay. When you order D-Luciferin Potassium Salt online, confirm the supplier's recommendations for both storage and handling of both the solid and reconstituted forms.

Vendor Selection: Your Strategic Partner:

Choosing the right vendor is as crucial as selecting a high-quality product. Consider the following when evaluating potential suppliers for your CAS 115144-35-9 needs:

  • Manufacturing Expertise: Does the vendor have a proven track record in producing and supplying fine chemicals? For bulk requirements, a direct D-Luciferin Potassium Salt manufacturer is often preferable.
  • Quality Assurance: Look for suppliers who adhere to stringent quality control measures and can provide comprehensive documentation (CoA, MSDS).
  • Customer Support: Responsive customer service can be invaluable for technical inquiries, order processing, and resolving any issues.
  • Pricing and Lead Times: While quality is paramount, competitive D-Luciferin Potassium Salt pricing, especially for bulk quantities, is a significant consideration for budget management.
