In the dynamic field of pharmaceutical research and development, accurate and efficient methods for assessing drug efficacy and cellular toxicity are paramount. Among the various tools available, the Sulforhodamine B (SRB) assay has emerged as a gold standard for cytotoxicity screening. This protein-specific fluorescent dye offers a unique combination of simplicity, reproducibility, and cost-effectiveness, making it an indispensable asset for laboratories worldwide. As NINGBO INNO PHARMCHEM CO.,LTD., we are dedicated to providing high-quality reagents that empower researchers to make groundbreaking discoveries.

The principle behind the SRB assay lies in its ability to bind stoichiometrically to cellular proteins. When cells are exposed to a test compound, their protein content can be quantified by measuring the amount of bound SRB dye. This measurement, typically performed at 510 nm, directly correlates with cell number or biomass, providing a clear indication of drug-induced cytotoxicity. This method is particularly advantageous for large-scale screening of potential anticancer drugs, as it allows for rapid analysis of numerous samples within a short timeframe.

One of the key benefits of utilizing Sulforhodamine B is its versatility. Beyond cytotoxicity, SRB is also an effective fluorescent dye for cell quantification and is widely used as a polar tracer. Its water solubility and distinct fluorescence properties enable its application in studies of cell morphology and neuronal cell-cell communication. Researchers can leverage these properties for advanced biological tracing and to gain deeper insights into cellular processes. The ability to use SRB for fluorescent labeling for cell growth studies further underscores its broad utility.

For those looking to buy Sulforhodamine B, NINGBO INNO PHARMCHEM CO.,LTD. ensures a reliable supply of high-purity SRB, meeting the stringent demands of scientific research. Our commitment as a trusted Sulforhodamine B supplier means that researchers can depend on consistent quality for their experiments.
