trptone soy agar, tripticase soy agar, tryptic soy agar? - are they all the same thing? (Aug/29/2007 )

Hi,

I want to order some TSA but I keep finding different names for it...trptone soy agar, tripticase soy agar, tryptic soy agar are they all the same thing?

They are all the same thing - soy protein digested with trypsin. (with agar added)
