Janus Green cell normalization stain

Product details

Ready-to-use green stain for normalizing antibody signal intensity to total cell amounts during in-cell ELISA (ab111622).

Cells fixed to a solid surface (typically in microplate wells) can be stained by adding 1X Janus Green Stain. Incubate cells for 5 minutes at room temperature. Dye should be removed and washed 5 times in ultrapure water or until excess dye is removed. The last wash should be removed and add 0.1 mL 0.5 M HCl per well and incubate for 10 minutes. Shake the plate for 10 seconds, and measure the OD 595 nm using a standard microplate spectrophotometer.
