A solution of a predetermined concentration of polyethylene glycol (PEG) was used in the preparation of purified vaccine preparation for this class. What does PEG do and how does it work?
Homework Answers
Polyethylene glycol help in the precipitation of viral genetic material, this mechanism of PEG of used in vaccine preparation
For any vaccine deactivated organism is injected, then our immunity starts working and start preparing antibody against the organism. In hepatitis B vaccine preparation , inorder to precipitate viral genetic material PEG is used. This deactivated viral genetic material can be used as vaccine
