In the intricate world of biochemical research and diagnostics, precise labeling of biomolecules is fundamental. Fluorescein 5-isothiocyanate, commonly known as 5-FITC (CAS 3326-32-7), stands out as a premier fluorescent labeling agent. Its ability to covalently bind to proteins and other biological entities via their amine groups makes it an indispensable tool for researchers worldwide. If your laboratory or company requires this essential reagent, understanding its applications and where to buy it is crucial.

Why 5-FITC is Essential for Labeling

The isothiocyanate group (-N=C=S) on 5-FITC is highly reactive towards primary amines found on amino acid residues (like lysine) and N-termini of proteins and peptides. This reaction forms a stable thiourea linkage, effectively attaching the highly fluorescent fluorescein moiety to the target molecule. The resulting conjugates are readily detectable using fluorescence microscopy, flow cytometry, and a variety of other fluorescence-based detection systems. This makes 5-FITC a key component in developing immunological assays, diagnostic kits, and probes for cellular imaging.

Sourcing High-Quality 5-FITC: A Procurement Focus

For procurement specialists and researchers, sourcing high-quality 5-FITC is not just about finding the lowest price; it's about ensuring the reagent's performance and reliability. When you aim to buy Fluorescein 5-isothiocyanate, look for suppliers who can provide detailed technical specifications, purity analysis (e.g., HPLC, NMR), and batch-to-batch consistency. A reputable 5-FITC manufacturer will also offer clear storage and handling guidelines, as the compound's stability is key to its efficacy. Many leading suppliers, including those offering 5-FITC for sale from China, provide competitive options for both research and bulk quantities.

Choosing Your Supplier: Value Beyond Price

While competitive pricing is a significant factor when you decide to purchase 5-FITC, consider the overall value proposition. A trusted supplier of Fluorescein 5-isothiocyanate should offer excellent customer support, efficient shipping, and a commitment to quality assurance.
