Addendum... I should have included this information in my original posting...

I'm already doing a 3% H2O2 peroxidase quench (10-15 minutes) and a 10% normal serum protein block prior to primary Ab, and a 2-4% case species serum addition to the link Ab.  

Is there something ELSE that I could use to block binding to platelets (or what appears to be platelets, though it could be bits of proteinaceous cellular debris that's binding Ab nonspecifically)?

Hi all,

Has anyone ever encountered platelets staining nonspecifically when using an antibody directed against other antigens?  If so, how do you quench that activity?  Thanks.
