The quest for high-performance reagents is a constant in scientific research and development. Fluorescein 5-isothiocyanate (5-FITC), identified by its CAS number 3326-32-7, is a crucial fluorescent dye extensively used for labeling biomolecules. For procurement managers and researchers, knowing where and how to buy 5-FITC is vital for ensuring the success of their projects, from laboratory experiments to commercial diagnostics.
Understanding the Power of 5-FITC
5-FITC is an organic reagent that features an isothiocyanate group, which readily reacts with amine groups on biomolecules such as proteins, antibodies, and peptides. This reaction creates a stable covalent bond, effectively attaching the highly fluorescent fluorescein molecule. The resulting conjugates emit a characteristic green fluorescence when excited, making them invaluable for a variety of applications including:
The growing applications in these fields underscore the consistent demand for quality 5-FITC from reliable sources.
Key Considerations When You Purchase 5-FITC
When you are ready to purchase Fluorescein 5-isothiocyanate, several factors should guide your choice of supplier:
