Neutral red uptake assay for the estimation of cell viability/cytotoxicity the cells are subsequently washed, the dye is extracted in each well and the . Neutral red is a dye that is taken up by a specific type of mouse embryo cells (balb/c 3t3 cells) where it accumulates in the lysosomes / endosomes. Kinetic studies on the internalization of lysotracker probes indicate that the rates of uptake of these dyes into living cells dye by live yeast results in red .
The uptake of neutral red dye in a yeast cell using different solutions abstract every cell transports materials in and out throught something called a membrane. Live cells incorporate neutral red into their lysosomes as cells begin to die, their ability to incorporate neutral red diminishes thus, loss of neutral red uptake corresponds to loss of cell viability it is also used to stain cell cultures for plate titration of viruses neutral red is added to some growth media for bacterial and cell cultures it usually is available as a chloride salt neutral red acts as a ph indicator, changing from red to yellow between ph 68 and 80.
