Summary Introduction

The ability of the pathogen to cause an infectious disease is measured in terms of pathogenicity and virulence. The cumulative effect of interaction of the pathogen with host which helps to measure the pathogenicity is termed as virulence. Virulence would be different for different microorganisms and will vary from one strain to another strain. Virulence can be quantified in terms of LD50 by the presence of lethal pathogen and a suitable animal model.

Molecular Biology Question You are working to characterize a novel protein in mice. Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas. What is the most likely explanation for this result?
