In the realm of biological and chemical research, fluorescent labeling reagents are indispensable tools that enable visualization and quantification of molecular interactions. Fluorescein 5-isothiocyanate, widely known as 5-FITC and identified by its CAS number 3326-32-7, is a prime example of such a reagent. Its vibrant fluorescence and reactive properties make it a staple in numerous scientific applications. If you are looking to buy 5-FITC, understanding its function and sourcing options is crucial for your laboratory's success.

The Versatility of 5-FITC in Labeling Applications

5-FITC is an organic compound characterized by its fluorescein core and an isothiocyanate group. This functional group is highly reactive with nucleophiles, particularly the amino groups found in proteins, peptides, antibodies, and even modified oligonucleotides. The resulting covalent linkage creates a fluorescent conjugate that can be easily detected. This capability makes 5-FITC essential for:

  • Cellular Imaging: Visualizing cellular structures and tracking molecular localization.
  • Immunoassays: Detecting and quantifying specific antigens or antibodies in techniques like ELISA and Western blotting.
  • Flow Cytometry: Analyzing cell populations based on fluorescent markers.
  • Diagnostic Kit Development: Contributing to the creation of sensitive and specific diagnostic tools.

The demand for reliable sources to purchase Fluorescein 5-isothiocyanate continues to grow with the expanding applications in life sciences.

Navigating the Market: Finding a 5-FITC Supplier

When seeking to acquire 5-FITC, it is important to identify reputable suppliers who can guarantee product quality and consistency. A good 5-FITC supplier will provide detailed product specifications, including CAS number, purity, and spectral properties. Furthermore, competitive pricing for various quantities, from research-scale to bulk industrial orders, is a key consideration. Many users prefer to buy directly from a manufacturer to ensure product integrity and favorable terms.
