Expression of AID mRNA in human non-Hodgkin lymphomas.

cDNA pools were prepared from cALL, DLBCL, FL, MCL, IC, MALT lymphoma, B-CLL, and MM. The cDNA of AID (nt 200-520), c-myc (nt 594-893), blimp-1 (nt 421-824), bcl-6 (nt 248-547), and β-actin (nt 391-660) was amplified by PCR. PCR products were separated by agarose gel electrophoresis and hybridized with an internal radiolabeled oligonucleotide. A representative autoradiograph with the PCR products of one individual tissue sample for each NHL entity is shown.
