FIG. 7.

(A) Electrophoretic analysis in 18% polyacrylamide of proteins immunoprecipitated with anti-gN or anti-gM from CV-1 cells labeled with [³H] leucine, infected with vvT7, and transfected with pTM1 vector alone, pTM1-gN (gN), or pTM1-gN and pTM1-gM (gN/gM). (B) All proteins were immunoprecipitated with anti-gN and were incubated overnight in buffer or buffer containing neuraminidase from Arthrobacter (na/Arth) before being subjected to electrophoresis. Sizes are indicated on the right in kilodaltons.
