[Nelson Salazar]

Dear Friends,

                I am looking for a cat positive serum for 
Toxoplasmosis, i. e. containing Ig G and Ig M. This will be used as a 
reference serum in ELISAs which will be carried out at the Veterinary 
Department -La Salle University in Bogota, Colombia.

Thanks very much for your help and I look forward to hearing from you.

              
                Sincerely,
                          
                            N. Salazar
