Abstract
Cytoplasmic RNA was isolated from cells cultured with LPS and LPS plus a T cell-derived supernatant (SN) (PK 7.1) containing B cell differentiation factors. The steady state levels of isotype-specific mRNA were assessed by Northern blot analysis with gamma-specific CH3 probes. It was demonstrated that the SN induces an increase in the level of mRNA for gamma 1 and a concomitant decrease in the levels of mRNA for gamma 2b and gamma 3.
