Paraformaldehyde and autofluorescence.

I perform immunophenotyping of human lymphocytes by flow cytometry.
I use 1% paraformaldehyde solution (PFA; Sigma) in PBS for cell fixation.
The autofluorescence of fixed cell exited at 488nm is increased 6-7 fold
comparing to nonfixed control.
1. Can someone suggest me an alternative PFA source which gives
2. Can someone suggest me a post-fixation protocol which reduces
PFA-fixed cell autofluorescence?
