Buffers, Solutions, and Dyes

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.

Buffers and Solutions by Application

Save time on experimental setup and preparation with premade and easy-to-use buffers for various applications.

Flow Cytometry – Gently fix cells stained with tandem dyes using FluoroFix™ Buffer, permeate cells for intracellular staining with the Cyto-Fast™ Fix/Perm Buffer Set, stain for transcription factors with True-Nuclear™ kits, and sensitively detect phosphorylated proteins using True-Phos™ Perm Buffer.

Immunohistochemistry – Reliably prepare slides for IHC staining and microscopy using  Retrieve-All Antigen Unmasking Systems.

Western Blot – Utilize Western-Ready™ reagents, including the Western-Ready™ ECL Substrate Kit that provides high sensitivity and extended signal duration, to get accurate and reproducible results.
