In addition to Serotec and BD, you may be interested to check
Coulter/Immunotech's IOTest HLA-B27/HLA-B7. This product is not
available in the USA, but I don't think that the restriction applies to
Canada.

The combo reagent should help with the B7 cross reactivity
problem.
See //WWW.COULTER.COM/ss000212.htm#HLA-B27-HLA-B7/ if you are
interested.
