By using a live dead stain, you can remove the cells that could be reporting a false signal and therefore be more confident in your data. 2.2 Wash the cells once with 1 mL of PBS. Calcein-AM, acetoxymethyl ester of calcein, is highly lipophilic and cell membrane permeable. I am trying to perform live dead assay in a mammalian cell line. The Yeast Viability Kit uses Invitrogen FUN 1 dye and Calcofluor White M2R. Historically, techniques such as PCR, flow cytometry and antibody immunocytochemistry staining were limited by analyzing cellular events as a snapshot rather than in real-time. These assays are based on the reaction of a fluorescent reactive dye with cellular amines. The region R1 contains particles of the appropriate size for yeast cells; the forward scatter trigger is set to exclude debris in the sample. 1. 3. 3D Cell Culture- Live/Dead/Total Cell Triple Staining. For dead cell exclusion, resuspend cell pellet in 0.5 mL of Cell Staining Buffer and add 5 µl of 7-AAD per million cells and incubate for 5-10 minutes in the dark before analysis. Retention of LIVE/DEAD Fixable Dead Cell Stains after fixation. The Live/Dead Cell Double Staining Kit is utilized for simultaneous fluorescence staining of viable and dead cells. Cells in (A) were not fixed; cells in (B) were fixed in 3.7% formaldehyde following staining. These assays are based on the reaction of a fluorescent reactive dye with cellular amines. Use 200 A.
