Description

Application

• Evaluation of ethylenediaminetetraacetic acid, tetrasodium salt dihydrate (EDTA)-Tween 20 treatment versus protease digestion of formalin-fixed tissue sections for detection of bovine respiratory syncytial virus antigen in infected ovine lung.: This study compares the effectiveness of EDTA-Tween 20 treatment against protease digestion for detecting bovine respiratory syncytial virus antigen in formalin-fixed tissue sections of infected ovine lungs. The findings indicate that the EDTA-Tween 20 method is a viable alternative, offering a more efficient approach to antigen detection in veterinary pathology (Meehan et al., 1989).

Biochem/physiol Actions

Ethylenediaminetetraacetic acid (EDTA) is used to eliminate enzyme inhibition by traces of heavy metals, and to inhibit enzymes that require divalent cations as cofactors.
