If it has a use by date you are supposed to observe that date. I personally would ignore the use by date and use it
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
To make the Eosin Methylene BLue Agar look cool and hip.
Methylene blue is an example.
Methylene blue is helpful to observe cells through a violet-blue color, making organelles, as well as the cell, easier to identify.
Active enzymes within living cells cause methylene blue to become colorless. Since dead yeast cells have inactive/denatured enzymes, the methylene blue stays blue.
i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)

Methylene blue stains everything blue.
The methylene blue will make the paramecium very horny and secrete sperm.
METHYLENE BLUE has high molecular weight.
It is blue, like its name.

Nope - methylene blue is a stain. You need liquid indicator like phenolphthalein that responds to pH changes.

the ph of the stain on the bacteria caused by methylene blue would not affect it a lot since all methylene blue is supposed to do is make it visible on the microscope for e.g.
