Samples were boiled in 1% SDS sample buffer, proteins were separated in Tricin SDS–PAGE (), blotted on PVDF membrane and immunologically detected with a polyclonal rabbit anti-SSB serum. () Cell extract from (lane 1) compared with 200 ng purified recombinant SSB (lane 2). () Lane 3, RDP268 (pSF1-SSB) cells express only SSB; lane 4, RDP268 (pACYCssb) cells express only SSB; and lane 5, purified recombinant SSB (15 ng). Lane 3 and lane 4 contain equal amounts of cells.
