We usually try to use absorbed or isotype specific secondaries whenever
possible for animal tissue. Vector usually provides crossreactivity data
with their secondaries which can also be helpful. Also, if you have to use a
mouse monoclonal on mouse tissue I've found the ARK kit from Dako to be
useful as well as the HistoMouse kit from Zymed. I don't use the CSA kit so
I can't answer your second question.
