FIG. 5.

Activity of RcRE deletion mutants of pcK30. The HIV Gag precursor in cell lysates was determined after cotransfection of the indicated pHIVgagdel vectors (for exact positions of deletions, see Materials and Methods) into HLtat cells with the effector plasmid pRec or p(−) (A), pRev (B), or pRex (C). Error bars indicate average deviations.
