The CSA terminology refers to tyramide amplification, DAKO has the CSA.
There are many publications in Journal of Histochemistry and Cytochemistry
on tyramide amplification methods, excellent reading.  Go back into
Archives, it was discussed at great lengths some time back.  If I recall,
Dupont/NEN has sold their technology to Biogenex, and possibly Ventana, and
certainly Molecular Probes, beisde CSA with DAKO.  I would contact DAKO
about this.    

Barb Wright, at Genetech, is a wizard with this method, and it works very
well once you get it up and running.  Her results are outstanding.  She is
out right now, just sent a message saying she was out of office for a short
time.
