Dear Histonetters, Does anyone know a vendor for anti-Trypsin and anti-Chymotrypsin antibodies that work on formalin fixed paraffin embedded tissue. I have alpha-1 antitrypsin and alpha 1 antichymotrypsin but our pathologists do not want the "alpha 1" type of these antibodies. Thanks in advance Elaine Dooley HTL 352-265-0111 ext 72117
