Thanks Andi
I had tried the Tordji-22 when it first came out but also could not get good
consistent results.  I just got the Biodesign clone 861 that marks Core Caspid
protein /MProtein (AA1-124) and  is supposed to work by IHC. I will try it out
next week. We are testing the MMM33 by western as well.  I will fill you in when
we get results. Did you see the 8 December  issue of science?  We are using the
same system for control. Happy Holidays
