[Histonet] EBER ISH

[Lanigan, Christopher]

Hi Sheila,

 

Sorry for the delay.

 

Yes, I am familiar with the EBER ISH probes on the Ventana Benchmark
Ultra.  

Yes, the software that you will need to have installed is called "U -
ISH OPEN PROBES - CHROMOGENIC v3".

This protocol will use the BLUE DETECTION and with a RED STAIN II
counterstain.

 

Before I get to the protocol, I'll fill you in on the probes.  

They do NOT arrive in a dispenser.  They come in pre-diluted vials, and
you will need to fill a "user-fillable dispense".  

One more thing, you will need to run a control.  This control will
confirm the presence of non-degradated RNA.  The control I used was U6,
and the protocol is identical to EBER except for the selected ISH probe.


 

By the way, the selected ISH probe will likely be "ISH PROBE 1" or "ISH
PROBE 2" because the user-fillable dispenser will not have the proper
commercial bar code. 

 

Finally, the following is a successful protocol summary (HybReady Soln
is optional for high background): 

 

1 Deparaffinization [Selected]

2 Warmup Slide to [69 Deg C], and Incubate for 16 Minutes (
Deparaffinization )

Histonetters,

 

Is anyone out there using the EBER ISH probes from Ventana on the Ultra

Platform?  I have a few questions.  Did you need to get new software

installed?  Was there any training involved?  And do you have successful

protocols that you are willing to share?

 

I have asked the questions before, but at the time there was nobody
actually

using it.  I know that there were inquiries about the protocols because
of

the ASR status and the fact that Ventana cannot give  you any advice.

 

Any and all information would be greatly appreciated since we are
wanting to

start it up at our facility.

 

Thanks,

 

Sheila
