The second glycopolypeptide (F0) appears to be cleaved in purified measles virus. Defective interfering particles accumulate during passage of measles virus leading to a decrease in the amounts of virus-specific protein synthesized in infected cells. Even in the best preparations of purified measles virus, host proteins are always detected and these become more predominant in preparations with low infectivity. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-44-1-135
