Fig. 3. Plasma cell expression of transcription factors. / The expression of Blimp-1 and BCL-6 by E/Pāˆ’/āˆ’ plasma cells or wild-type IgM+ B cells was determined by Western blot using rabbit polyclonal antiserums. The murine plasmacytoma cell line, J558, served as the positive control (+) for Blimp-1 expression and BJAB cells served as the positive control (+) for BCL-6 expression. A representative experiment of 2 independent plasma cell and IgM+ B cell isolations is shown.
