RE: [Histonet] Automation Ventana vs. Dako

From:"Carla Frenchko"

Linda you write much more eloquently than I. What I was trying to convey
is that in an open system any antibody or reagent can be used on the
system, including detection.

Misconception here:  you can run antibodies from any company on Ventana
instruments either by putting them in a user-fillable Ventana dispenser
or by manually applying the antibody in a titration mode run.  We do
both of these as well  as use some of Ventana's antibodies.

The only thing you  are "married to" is their detection chemistries,
biotin block (if using) and  amplification (if using).  You can employ
your own enzyme digestion reagent and counterstain if desired.  If
performing antigen retrieval on line, you also are wed to  Ventana's
Cell Conditioning solutions (HIER buffers)....although nothing prevents
you from using your own HIER methods and reagents off-line which is what
we do when using our NexES instrument.

Just trying to clear a few things up.

With all due respect to Heather; but the reason the Ventana is not
really an "open" system is that you are "married" to a particular
vendor's antibodies and detection. In a true "open" system most any
company's antibodies will run with the instrument's detection
(specifically speaking of both the Dako and Biogenex instruments having
run both).

As an ex Ventana Tech Rep (not sales) I can say that you really have to
judge what instrument is best suited for your volume and your staffing.
Ventana is a great company with a great product but, very expensive.
Can you rely on it-yes, Can any tech run it with minimal training-yes.
Have they had lot issues with detection, sure but name a company that
hasn't run into that at some point.  Dako on the other hand is very
reliable and has the market on good antibodies. Can anyone run it-not
without a bit of hands training.  It seems to be more affordable than
Ventana but, you have to have a good staff that can consistently
reproduce steps and make up dilutions.  With Ventana you can cut, dry,
put it on the instrument and then walk away-reproducible and consistent
pretty much every time.  With Ventana you can also create an open system
and run some great Dako antibodies or any other vendors products for
that fact.  Your only marrried to their detection.  Both companies seem
 to have good tech support and Dako has allot of really sharp
publications to get you off and running.  Unfortunately in today's
histology labs we are seeing such an increase in staffing changes that
it is sometimes better to pay the extra money and let the Ventana
Benchmark do the work and not worry about it.  On the other hand if you
have a good tech staff that can be "cooks in the kitchen" than Dako
seems to be a pretty good instrument too.  I welcome you to listen to
your peers-its just simply finding out which company will suit your
needs and what your budget will endure.  Just my un-bias two cents.  I
wish you all the best in your decison making process.
