These are actually two separate questions:
We would be interested to know from those using the Optimax immunostainer in
open mode- what detection system are you using?

The second question is regarding the Signet USA (ultrastreptavidin)
detection system.  We would like to hear from those using this system how it
compares with LSAB and/or Envision detection.

Thanks again for your input!
