I would recommend contacting Dr. Ronald Casciato at Signet Laboratories.  He used to be affiliated with Ortho.  Signet's telephone number is (800) 223-0796.

Hi all,
Is anyone aware of a distributer for ortho Ab's? The last time we ordered
from them was 1993, and it seems they were bought out by Johnson and
Johnson.
Thanks
Barb
