Case 1. A: CDRIII PCR of microdissected tissue obtained from a
CD5-stained section. Lane mw: Molecular weight standard.
Lanes 1 and 4: CD5+ MCL compartment. lanes 2
and 3: CD5-FL compartment. Lane n: negative control.
Lane p: polyclonal control
(microdissected reactive
follicle). In addition to a weak band of the
same size as the MCL compartment, the FL lanes show a second band of
different size. Each lane represents a separate microdissection.
B: Southern blot of bcl-2 PCR products obtained from paired
microdissections with ∼30,000 cells (Lanes 1 and
2), 15,000 cells (Lanes 3
and 4), and 5000 cells
(Lanes 5 and 6).
Lanes 1, 3, and 5 show results obtained from the MCL
compartment and Lanes 2, 4, and 6 those from the FL
compartment. Lane w: PCR product from whole tissue section.
Lane p: positive control. The weak signal in Lane 1 probably
results from contaminating FL lymphoma cells.
