In the dynamic landscape of scientific research, analytical reagents that offer sensitivity, specificity, and reliability are highly sought after. Fluorescein Sodium (CAS: 518-47-8) is one such compound, a well-established fluorescent dye that has found extensive use as an analytical reagent and a versatile tool in biological and chemical research. Its inherent fluorescence, coupled with a high degree of purity often available from dedicated manufacturers, makes it invaluable for a wide range of experimental techniques.

One of the most significant applications of Fluorescein Sodium in research is its use as a protein label. By conjugating fluorescein to antibodies or other biomolecules, researchers can track the location and dynamics of specific targets within cells or tissues using fluorescence microscopy. This technique is fundamental in fields like immunology, cell biology, and molecular diagnostics. The bright emission of fluorescein allows for sensitive detection, even at low concentrations, aiding in the study of protein-ligand interactions, cellular localization, and disease biomarkers. Scientists often look to buy high-quality fluorescein-labeled reagents or the raw Fluorescein Sodium itself to create their own conjugates, seeking competitive price and reliable supply from specialized suppliers.

Beyond protein labeling, Fluorescein Sodium serves as a crucial reagent in various other analytical procedures. It is employed in studies of microvascular permeability, acting as a test molecule to probe the integrity of blood barriers. Its ability to pass through permeable membranes but not others allows researchers to quantify leakiness in vascular beds, which is vital for understanding disease states and drug delivery mechanisms. For researchers in pharmacokinetics and physiology, sourcing consistent and high-purity Fluorescein Sodium from trusted manufacturers in China is essential for accurate experimental outcomes.

The chemical properties of Fluorescein Sodium, including its solubility and fluorescence excitation/emission spectra, are well-characterized, making it a predictable and controllable reagent. This predictability is crucial for developing new analytical methods and assays. When considering how to purchase this compound, laboratories often prioritize suppliers who can provide detailed specifications, certificates of analysis, and competitive bulk pricing. This ensures they are acquiring a reagent that meets stringent research standards.
