High Quality Fluorescein CAS 2321-07-5 is a well - known fluorescent dye with a high purity level. Its Chemical Abstracts Service (CAS) number is 2321 - 07 - 5, which serves as a unique identifier in the chemical industry. The product is typically presented in a fine powder form, which allows for easy dissolution and handling.
The molecular formula of Fluorescein is C₂₀H₁₂O₅, and it has a molecular weight of approximately 332.3 g/mol. It exhibits intense fluorescence under ultraviolet or blue light, with an excitation peak around 490 nm and an emission peak around 520 nm. This high - intensity fluorescence makes it a popular choice in many applications.
High Quality Fluorescein has a wide range of applications across different fields. In the biological and medical fields, it is commonly used as a fluorescent tracer for cell imaging. It can be conjugated to antibodies or other biomolecules to track and visualize specific cells or cellular components within a biological sample.
In the environmental field, Fluorescein can be used as a tracer in water systems. It helps to study water flow patterns, detect leaks in pipelines, and monitor the movement of pollutants in water bodies. In the industrial sector, it is used in fluorescent markers for quality control and product identification. For example, it can be added to plastics or coatings to make them fluorescent for easier detection and sorting.
When using High Quality Fluorescein, it is important to follow proper safety and handling procedures. First, wear appropriate personal protective equipment, such as gloves and safety glasses. To prepare a solution, dissolve the powder in an appropriate solvent. For most applications, distilled water or a buffer solution can be used. The solubility of Fluorescein may vary depending on the solvent and temperature.
For biological applications, the prepared solution should be sterile - filtered to remove any potential contaminants. The concentration of the solution should be adjusted according to the specific application. In general, a lower concentration may be sufficient for cell imaging, while a higher concentration may be required for environmental tracing.
Cell Imaging in Biology: In a recent research project, scientists used High Quality Fluorescein to label a specific type of cancer cells. They first conjugated Fluorescein to an antibody that specifically binds to a surface protein on the cancer cells. After incubating the labeled antibody with the cell sample, they were able to visualize the cancer cells under a fluorescence microscope. This allowed them to study the distribution and behavior of the cancer cells in the sample, which is crucial for understanding the progression of the disease and developing new treatment strategies.
Water Tracing in the Environmental Field: A local water utility company used Fluorescein to detect a leak in a large - scale water pipeline. They injected a small amount of Fluorescein solution into the pipeline at a specific point. By monitoring the fluorescence downstream, they were able to identify the exact location of the leak. This not only saved a significant amount of water but also reduced the cost of pipeline repair.
