Selecting the right reagent for cell viability assays is crucial for obtaining accurate and reproducible results. While MTT has been a long-standing option, WST-8 (CAS 193149-74-5) has increasingly gained prominence due to its advanced features. For researchers aiming to optimize their assays, understanding the differences between these two tetrazolium salts is essential. NINGBO INNO PHARMCHEM CO.,LTD., as a leading manufacturer and supplier, provides high-quality WST-8 and insights into its advantages.

The primary distinction between WST-8 and MTT lies in their respective formazan products and assay protocols. MTT yields a water-insoluble formazan precipitate, necessitating an additional solubilization step using organic solvents like DMSO or isopropanol. This step can be time-consuming, and the solvents themselves can be toxic to cells or pose safety risks. In contrast, WST-8 produces a water-soluble formazan. This means the resulting dye can be directly measured in the supernatant without any solubilization step, significantly simplifying the assay procedure. This inherent simplicity makes WST-8 a more user-friendly option, especially for high-throughput screening. If you're deciding where to buy WST-8, consider the streamlined workflow it offers.

Sensitivity is another key area where WST-8 often outperforms MTT. WST-8 is generally considered more sensitive in detecting metabolic activity, allowing for the measurement of lower cell numbers or more subtle changes in cellular health. This enhanced sensitivity is particularly beneficial when working with sensitive cell lines or when evaluating the efficacy of compounds at very low concentrations. Moreover, WST-8 itself is non-toxic to cells, enabling researchers to perform longer incubations, up to 24 hours, without negatively impacting cell viability. This extended incubation period provides greater flexibility in experimental design and can lead to more comprehensive data. The WST-8 price reflects its advanced capabilities and ease of use.

When considering where to buy WST-8, choosing a reputable manufacturer and supplier like NINGBO INNO PHARMCHEM CO.,LTD. is vital. We ensure high purity and lot-to-lot consistency, guaranteeing reliable performance in your assays. While MTT is a viable option, the procedural advantages, enhanced sensitivity, and non-toxicity of WST-8 make it a compelling choice for modern cell viability studies. For researchers looking to upgrade their assays and improve efficiency, purchasing WST-8 from a trusted WST-8 supplier in China is a strategic decision.
