Hello All,
Any of the veterinary folks out there know of a source for an Elisa kit 
to Mycobacterium bovis or in lieu, antibodies to said bacterium?

I'm also looking for a commercial source for "purified protein 
derivative" (PPD) for M. bovis. 

My friend wishes to innoculate inexperienced cows (ie M. bovis 
negative) with the PPD and then measure their immunoreactivity by 
an Elisa method.

Thanks in advance.
Greg
