Evaluation of H-2Kb-tsA58 transgenic mouse-derived immortal splenocytes producing antibodies against intact phage particles and against the pIII phage capsid protein. 1, culture medium, negative control; 2, preimmune serum; 3–7, supernatants derived different monoclonal lines after 8 weeks in culture. 4, 5, and 7 react strongly with the pIII protein and, at this concentration, also react with intact filamentous phage particles. Bars correspond to the mean. Standard errors of the mean were <1% of the mean.
