Selecting the appropriate buffer is a critical decision for any scientific researcher, as it directly impacts experimental outcomes. While a variety of biological buffers are available, each possesses distinct properties that make them suitable for specific applications. This article provides a comparative analysis of CAPSO Sodium Salt (CAS 102601-34-3) against other common biological buffers, focusing on key parameters such as pH range, metal ion binding, and water solubility. As a leading supplier, we aim to equip scientists with the knowledge to buy the most effective reagents.

CAPSO Sodium Salt is a zwitterionic buffer with a pKa of approximately 9.6, making it highly effective in the pH range of 8.9 to 10.3. This high pH buffering capacity distinguishes it from many 'Good' buffers like HEPES (pH 7.2-8.2) or MOPS (pH 6.5-7.9). For applications that require significantly alkaline conditions, such as certain protein transfer protocols in electrophoresis or specific enzyme assays, CAPSO Sodium Salt offers a superior solution. When you need to buy a buffer for high pH applications, CAPSO Sodium Salt is often the preferred choice.

Another crucial differentiator is metal ion binding. CAPSO Sodium Salt is known for its minimal interaction with most metal ions, a property that is highly desirable in biochemical studies where metal cofactors or inhibitors might be present. Some other buffers, for instance, may exhibit moderate to strong binding with certain divalent cations, potentially interfering with experimental results. This makes CAPSO Sodium Salt an excellent option for sensitive assays where buffer-induced metal chelation could be problematic.

Solubility is also a significant consideration. CAPSO Sodium Salt demonstrates high solubility in water, facilitating easy preparation of stock solutions and experimental buffers. While many buffers are water-soluble, the degree of solubility can impact concentration limits and ease of use. As a manufacturer committed to quality, we ensure our CAPSO Sodium Salt is highly soluble and pure (≥99.0%), guaranteeing reliable performance for your research needs.
