Live/Dead Markers - RayBright® LIVE dyes
As understanding of the degree of cell death in a flow cytometry assay is critical towards any analysis of cell population, the use of live/dead markers remain essential to elucidate viability.
RayBright® LIVE dyes are amine-reactive fluorescent dyes that helping distinguish between live and dead cells in flow cytometry analysis. RayBright® LIVE dyes bind with a much brighter signal in dead cells than in living cells. Living cells refuse the dye while dead cells are stained both on the cell surface and intracellularly. Supplied frozen in DMSO solution at a pre-titrated concentration. Read more
Intracellular Staining Kits
The RayBiotech Intracellular Staining Kit is designed to allow for intracellular staining of target cytokines, proteins, or other factors in activated or treated cell populations. The kit includes both Brefeldin A and Monensin both of which inhibit the Golgi apparatus function, trapping normally secreted cytokine and proteins inside cells during incubation. Following incubation, the included saponin-containing buffer is used to permeabilize cells in order to allow intracellular antibodies entry through the plasma membrane. Read more
RayBio® Annexin V Apoptosis Kit (RayBright® V450)
The RayBiotech Annexin V Detection Kit is a sensitive assay of cell apoptosis by flow cytometry. Live and dead cells can be discriminated by RayBright Live/dead markers, a group of small organic dye. Unlike other apoptosis assay using propidium iodide (PI) or 7-AAD, RayBio Annexin V apoptosis Detection Kit can combine with further immunophenotyping that requires cell fixation. Read more
