I'm cleaning out an evacuated lab next door, as our group will be expanding into this space. I found a large bottle of 30% Acrylamide/bis (29:1) solution from BioRad. There doesn't appear to be an expiration date on the bottle, so I'm wondering if it's worth using - the lab it was in has been dead for >2years.. It's been stored in @4`C, and the shrink-wrap seal is intact. Thoughts?

Why does a science forum not have pictures of mice and rats?

Is there a lot number on the bottle? Call BioRad and ask.

Make a gel and try out....but I think this ready-made Acrylamide can be stored really long. I used it from bottles that looked older than me, without problems...
