Fluorescein Diacetate

Fluorescein Diacetate CAS: 596-09-8 | MF: C24H16O7 | MW: 416.38, Buy now for reliable and reproducible results from Tristains at Chemical World.

Fluorescein Diacetate (FDA) is an unfluorescent form of fluorescein having the molecular formula C24H16O7. It is also known as 3,6- Diacetoxyfluoran or Di-O-acetylfluorescein, and it easily enters cell membranes. It is broken down by esterases to produce fluorescein and a bright green fluorescence is formed in viable cells. This process renders Fluorescein Diacetate an effective, selective labelling and quantification agent of living cells in microbiology and cell biology.

Applications

  • Cell Biology and Live-Cell Imaging: Fluorescein Diacetate is widely used in cell viability assays. While non-fluorescent outside the cell, it is enzymatically converted to fluorescent fluorescein within viable cells, allowing clear differentiation between live and non-viable cells.
  • Bacterial Viability Testing and Microbiology: Applied in the determination of metabolic and esterase activity of bacterial cells, which supplements microbial viability investigations.
  • Flow Cytometry and Automated High-Throughput Screening: Works with fluorescent-based flow cytometry systems and automated platforms of large-scale analysis.

Key features

  • High Sensitivity: Detects very low levels of esterase activity, enabling precise cell viability determination.
  • Broad Range of Applications: Appropriate to microorganisms, fungi, plant cells, and mammalian cells.
  • Stable: Gives repeatable and reliable results in repeated experiments and with long shelf life.
  • Economical: Economical in large-scale research and recurrent assays.

General Description

Fluorescein Diacetate (CAS No. 596-09-8) is a common fluorescent viability reagent that is applicable in biological and diagnostic laboratories. It is an excellent selective marker of cellular activity because of its non-fluorescent nature in the absence of cells and its enzymatic activation in viable cells. Its analytical performance is great and its molecular weight is 416.38 g/mol, which enables the sensitive detection of enzymatic processes and tissue viability in research and quality control contexts.

Alternate Names Fluorescein diacetate is also known as Cellstain-FDA, Di-O-acetylfluorescein, and 3,6-Diacetoxyfluoran
Application Fluorescein Diacetate is a useful live-cell fluorescent stain that is hydrolysed to fluorescent fluorescein in live cells
CAS Number 596-09-8
Molecular Weight 416.38
Molecular Formula: C24H16O7
For Research Use Only. Not Intended for Diagnostic or Therapeutic Use. * Refer to Certificate of Analysis for lot specific data (including water content). Fluorescein diacetate stains living cells green, and is a substrate for esterases. Fluorescein Diacetate is suitable for use in cell viability assays. Removal of the acetate groups by cellular esterases results in fluorescence in cells with intact membranes.
