Hi Bukowski,

What Pre-PCR preps are you doing on the Zephyr? We mainly use ours for bead cleanups and that's it.
We use the NGS Express for some pre-PCR stuff. It's a bit limited if you want...

You can get ART 200ul extended length pipette tips that fit nicely into the wells and reach the bottom. Really good for mixing the primers in without the need for any sloshing.

Hi Tony,
Thanks for the response. Did you need to change the sequencing primers, or did you use completely different target primers for your initial PCR?

Hi Tony,
I know it's been a while, but have you been able to resolve your issue with the dim clusters? If so, what did you do to resolve the issue?
Thanks!

I was told by Roche that they want the engineers to install the update. Apparently in some cases it has killed the FLX+'s onboard computer.

I think you would need to dilute your sample to be sure it is in the range for the Pico chip. They use them here for some microarray stuff.

If running a 2x250bp run, you'll also want to get rid of some of the smaller fragments. That's why they tell you to use less beads for the longer runs.

It should be fine. I believe the chemistries are the same between platforms. You can use MV emPCR kits for the Jr, so beads from any of the SV or LV kits should be fine as well.
