Buffers - Solutions - Dyes
Using the right buffers, solutions, and dyes can be critical for assay performance and reliable results. They can also serve as experimental controls, or can help prepare samples for downstream applications. Find the optimal buffers and dyes to complement your toolset, either as preassembled kits or individual reagents.
Dyes and Chemical Probes
Non-antibody dyes and chemicals can be used to detect cell health, death, and division. Monitor cell viability with our fixable Zombie dyes and Helix NP™ probes that permeate dying cells. Track cell division with CFSE and Tag-it Violet™ kits, which utilize dyes that are retained by progeny cells for quantification of cell proliferation. Use MitoSpy™ probes to identify and stain mitochondria in live cells.
