Tools for Flow Cytometry

Flow cytometry is a laser-based technology used in cell sorting and analysis. Flow cytometry measures a particle’s size, granularity, and fluorescence intensity. Flow cytometry continues to a be a very useful tool and its importance in scientific research and diagnosis is increasing.

Flow cytometry allows researchers to measure several physical characteristics of cells including its shape, size, and internal complexity. It has long been used in cell counting and cell sorting but more recently, researchers have been using flow cytometry in a broad range of applications including: biomarker detection, cell signaling, pathway screening, protein engineering, and systems biology. Flow cytometry is inherently a robust technique that adapts easily to basic research, drug development, and diagnostics.

Multiplexing Flow Cytometry

Flow cytometry is a powerful tool that enables single-cell analysis of expression of different targets. Multiplexing different fluorophores and probes allows the collection of meaningful information and complete cell characterization.

Use the Spectra Viewer to determine which assays and fluorophores can be multiplexed together. In addition, discover which dyes are compatible with the lasers in your flow cytometer.

Drug Disposition: Multi-Drug Resistance Profiling

Detect Activity of All Three Major ABC Transporter Proteins

The Enzo Life Sciences multidrug resistance assays are the only available kits for simultaneous monitoring of all three major ABC transporter proteins — MDR, MRP & BCRP. The high sensitivity of the assay delivers fewer false negative results, and provides data for BCRP activity not detected in Calcein AM assays. The kits are easily incorporated into a high content screening environment making them ideal for drug screening applications.


 


ABC transporter protein activity was evaluated in CHO K1 cells by flow cytometry using EFLUXX-ID® Green (top), Gold (middle), or Calcein AM (bottom) dyes. Treatment with specific inhibitors of ABC Transporter proteins (shaded histograms) induces retention of dye within cells relative to untreated cells (lined histograms). The difference in mean fluorescence intensity (MFI) is an indication of the corresponding protein activity, as shown by MAF scores [multidrug resistance activity factors], a quantitative measurement of multidrug resistance. Higher MAF scores are a result of superior specificity of EFLUXX-ID® dyes to specific inhibitors. Calcein AM (a common probe for MDR assays), is unable to detect BCRP activity.
