Simply add 1-2 drops to determine your cell viability

Propidium iodide (PI) cell viability dye is used in Flow Cytometry to exclude dead cells by entering a cell with a compromised membrane and binding to double-stranded DNA and RNA.
It is available as a convenient ready-to-use solution: simply add 1 or 2 drops of the propidium iodide solution to assess the viability of your cells. Suitable for use in Flow Cytometry and Immunofluorescence Microscopy.

The ReadiDrop propidium iodide cell viability assay has a number of key benefits and these include:
Key characteristics and handling instructions of the ReadiDrop propidium iodide cell viability dye are:
We also offer fixable viability dyes in a range of excitation and emission spectra to enable easy incorporation into multi-color Flow Cytometry panels
