The alamarBlue HS and alamarBlue Cell Viability Reagents are ready-to-use resazurin-based reagents that function as cell health indicators by using the reducing power of living cells to quantitatively measure viability. Upon entering living cells, resazurin is reduced to resorufin, a compound that AlamarBlue Cell Viability Assay reagent quantitatively measures the proliferation of mammalian cell lines, bacteria and fungi. The dye incorporates an oxidation-reduction (REDOX) indicator that both fluoresces and change color in response to the chemical reduction of growth medium due to cell growth.
alamarBlueВ® assay for assessment of cell proliferation Resazurin is blue and non-fluorescent whereas resorufin is red and highly fluorescent. It is a sensitive assay if working with higher than 5x103 cells per 100 ОјL, relatively non-toxic and provided that it is (CELL VIABILITY) LIFE SCIENCES MEASURING CELL-VIABILITY BY RESAZURIN change from the oxidized-form (blue) to the reduced form-(red).

This protocol describes viability measurements for cell cultures in a 96-well tissue culture plate using alamarBlue (resazurin). The assay can be modified to accommodate larger plates; however Nov 15, 2012В В· The reduction of AlamarBlue results in a measurable color shift. The wavelengths for maximal absorbance are 570 nm and 600 nm for the reduced and oxidized forms of alamarBlue respectively. Because the wavelengths overlap it is necessary to measure the absorbance at both wavelengths. Protocol name: AlamarBlue-A.prt (Absorbance Readers)
Resazurin (7-Hydroxy-3H-phenoxazin-3-one 10-oxide) is a phenoxazine dye that is weakly fluorescent, nontoxic, cell-permeable, and redox‐sensitive. Resazurin has a blue to purple color (at pH > 6.5) and is used in microbiological, cellular, and enzymatic assays because it can be irreversibly reduced to the pink-colored and highly fluorescent resorufin (7-Hydroxy-3H-phenoxazin-3-one).
