Phenotypic Screening and In Vitro Toxicology: Applications of Far‐Red Fluorescing DNA-Specific Anthraquinones in Cell‐Based Assays
Phenotypic Screening and In Vitro Toxicology: Applications of Far‐Red Fluorescing DNA-Specific Anthraquinones in Cell‐Based Assays
5 Aug 2015This application note demonstrates a number of applications of Fluorescein-/GFP-compatible dyes, in particular DRAQ5 and CyTRAK Orange. The particular spectral and chemical features of DRAQ5 and CyTRAK Orange mean they are compatible with aqueous media and fixatives. Conveniently, they are supplied in aqueous solution and can be applied as the final step in a sample preparation. They have become standard reagents for immunofluorescence microscopy, flow cytometry and high content imaging.

Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems.

Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.
