Express method for detection of Amanita phalloides amanitine toxins.

Spectral studies of the interaction between amanitine and ethidium bromide fluorophore showed the appearance of a new intensive fluorescence band after addition of amanitine to ethidium bromide solution, caused by the formation of a charge-transfer complex. The new fluorescence band is located in a shorter wave region of the spectrum compared to ethidium bromide fluorescence band. Based on the results, a rapid fluorescent method for detection of amanitines was developed.

[A study of the peripheral quaternary ligand binding site of cholinesterase with the use of ethidium bromide].

The peripheral binding site of horse serum cholinesterase (EC 3.1.1.

Rapid method for diagnosis of abnormal activity of butyrylcholinesterase.

We present the results of spectral studies of the interactions between butyrylcholinesterase and ethidium bromide fluorophore inhibitor. The ethidium bromide fluorescence selectively increased in the presence of butyrylcholinesterase. A rapid method for evaluation of serum butyrylcholinesterase activity is developed.
