The polypeptide composition of avian infectious bronchitis virus particles	1977		.txt	text/plain	2683	221	78	The polypeptides of the different density virus particles from the three IBV strains were analysed on polyacrylamide gels. Other studies on the polypeptide composition of eoronaviruses have shown 6 polypeptides in the virus particles of human coronavirus (HCV) strain OC43 (7) a n d t r a n s m i s s i b l e g a s t r o e n t e r i t i s v i r u s ( T G E V ) (5), a n d 7 p o l y p e p t i d e s in t h e v i r u s p a r t i c l e s of H C V s t r a i n 229 E (8) Virus Polypeptide Analysis Figure 2 shows the polsTeptides of the purified major virus species of the IBV strains Beaudette, Connecticut and Massachusetts, on polyaerylamide gels.	./cache/cord-283804-dje7qbps.txt	./txt/cord-283804-dje7qbps.txt
