UV versus chemical polymerization of glycol methacrylate (GMA) in enzyme histochemistry

Acta histochemica
H von Mayersbach, I Höpfel-Kreiner

Abstract

The influence of the mode of polymerization of GMA on the enzyme activities of differently fixed rat livers was studied. It was found that with increasing time of UV-polymerization several enzyme activities were inhibited whereas chemical polymerization was comparatively less harmful. The histochemical reactivity of substrates such as glycogen was not impaired by the mode of polymerization, which is in contrast to the increased basophilia of DNA and RNA after UV-polymerization.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
