一般說明
Picric acid is a polynitrated aromatic acid. It dissolves in water to form a solution with low pH (pH 2.0). It interacts with basic groups of proteins, forms salts and coagulates them. Fixation with picric acid gives a bright stain, but there might be a loss of nucleic acids due to the low pH of the solution.
Picric acid is anionic and has a low molecular weight.
Picric acid is anionic and has a low molecular weight.
