It is mainly used for staining of spermatozoan nucleoproteins in adult males. During the maturation of sperm, the histotype conversion of basic proteins bound to the DNA of the sperm nucleus will occur. Histones rich in lysine residues will be gradually replaced by protamine rich in arginine and cystine residues. Under acidic conditions, aniline blue will bind to lysine residues to produce a blue or violet-blue compound, thus indicating the presence of proteins rich in lysine residues, while sperm with mature nucleoproteins will be stained to red..
