Good Morning Brianna,
  The Catalog number for the BD Pharmingen Ab is #554252.  Again, I use
it at a dilution of 1:100 with streptavidin HRP or ALP reagents from
Biocare Medical. I incubate the primary for 1 hour at room temp and,
incubate the secondary and tertiary for 15 mins each.  I'm also
attaching a couple of other special stains that I've found over the
years for eosinophils.  All my Best!! Cindy B
