Abstract

The microsomal fraction was isolated from homogenate of 125I-labeled leukemia L 1210 ascites cells by filtration of postmitochondrial supernatant through a Sepharose 4 B column. It was found that the particles are labeled with iodine and show 5'-nucleotidase activity suggesting the presence of cell membranes in the fraction. The soluble proteins fraction were retarded on the column showed lactate dehydrogenase activity, and low activity of soluble beta-D-glucuronidase.

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.
