High molecular mass complexes contain CBP and RNA pol II. Fractionation of T47D lysate on a Superose 6 column was analyzed by immunoblot with CBP and RNA Pol II-specific antibodies (CBP and RNA pol II). Recombinant baculovirus-expressed CBP also was fractionated (CBP BAC). Indicated are elution peaks of molecular mass markers: mammalian SWI/SNF complex (≈2 MDa) and thyroglobulin (670 kDa). The void volume (4 MDa for globular proteins) was determined at fraction 20 by silver staining after fractionation of T47D cell lysate (data not shown).
