Dear all, 

I'm currently trying to detect the signals of intracellular LC3 in isolated eosinophil from human blood. After being purified (the purity is ~ 99%) and treated, eosinophils are harvested, permeabilized immediately (with 0.1% Triton-X) and incubated with PE-LC3 antibody, and resuspended in 1X HBSS. Recently I got two problems: 

1/ Another cell populations shift towards SSC high/FSC high. This makes it harder to gate the general population.

2/ In some samples, signals of PE-LC3 were very high. So I think maybe it's due to unspecific staining. 

Is there anyone has encountered these problems? I appreciate any help you may provide.
