Bioanalyzer2100 RNA Pico Chips Expiry

[cement_head]

Hello,

For the actual plastic chips (RNA 6000 Pico), they all have an expiry date. Is this real? In other words, has anyone used unexpired reagents with expired chips for RNA Pico and gotten acceptable (normal) results?

If so, what is the "actual" lifetime of the RNA Pico Chips - do they ever truly expire?

Thanks

Short answer- no true expiry date.

I recently used Small RNA chips that expired in 2012 (I think, maybe 2013) with DNA High Sensitivity reagents and it worked just fine. They seemed to have a little more of an ammonia scent than normal, but I have done this a few times and it has always worked.

And in case you didn't know, all of the chips seem to be the same, just with a different label. So you can load any reagents on any chip, you just have to load the wells the way the reagent manual specifies.

Interesting, and what I suspected. Thanks!
