pellets with RIPA lysis buffer, on ice. Following brief sonication, lysates were
clarified by 12,000 × g centrifugation for 10–15 min. Samples
were loaded according to total protein content, determined by BCA assessment
(Thermo Pierce), and within each cell type the amounts were normalized to the
first mock-infected sample (corresponding to ~100,000 cells total per
lane). Antibodies and dilutions used: CSTF-64 (A301-092A), CSTF-77 (A301-096A),
and CFIm-68 (A301-356A): Bethyl Laboratories, 1:2000. CPEB1: Cell
Signaling Technologies (13583), 1:1000. β-actin: Sigma-Aldrich (clone
AC-15, A1978), 1:10,000. Ms anti IE (CH160): Virusys, 1:5000. Ms anti UL57:
Virusys, 1:1000. Ms anti UL99(pp28): Virusys, 1:1000. Ms anti UL83(pp65)
Virusys, 1:5000.
