Exalpha Corporation has a APC conjugated CD4 antibody (monoclonal) that has
been demonstrated (published in Cytometry) to bind macaque sp. monkeys (in
the pure form). Its cat. # is AP04 - I can not address the brightness
question directly, but the PE is extremely bright on human T cells.
Exalpha can be reached at: phone - 617.558.3265, or 800.395.1137, fax -
617.969.3872.
Sincerely,
John Castracane
