We have been optimising flow cytometric assays for cytoplasmic /
nuclear antigens and have encountered problems with myeloperoxidase

Our current method is Farahat (1994) J.Clin.Pathol.47,843-849

Basically this is an equal mixture of 4% PFA and BD's
lysing solution for ten mins, spin and resuspend in 0.5%
Tween 20 for 2 mins.

This gives good results for TdT and IgM.

The problem appears to be non specific binding
of anti-MPO-fitc (Dako).

Any comments on other anti-MPO-fitc conjugates,
blocking protocols or methods would be welcome.

Terry.
