Effect of size fractionation of CM of CAG18439 on cell-to-cell transformation and cell growth.
Effect of size fractionation of CM of CAG18439 on cell-to-cell transformation (A) and cell growth (B). CM was fractionated by ultrafiltration as described in Methods, and used for culture at 1% (v/v). Data are presented as mean and S.D. (n = 3). Co-culture of MG1655 harbouring pHSG299 and MC4100 was performed in the presence of CM.
