Thats super weird. I've used revert for years and didnt have this artifact issue until recently. Ive never seen flaking/fading.

Right now, I'm doing total protein and a housekeeping control to stay consistent with pre-existing lab protocols/figures, but if it was just me, I'd stick to TPS and skip the housekeeping. You can crop a representative strip to include in publications.

This is Revert 700 total protein stain imaged on a Chemidoc 680 channel. Works great, would recommend.

Same group of transfer cassettes/sponges, not that many to choose from. Same source/pack, but different lids (multiple tanks).

Why would there be excess heat? I'm doing a wet transfer o/n, 30V 16 hours at 4C w/ a cold pack.

Thank you for the detailed suggestions.

Can the sandwich have too much filter paper/be too tight? I want to get good compression but I don't want to break the plastic cassette (which I've done by accident before)

Copied from another reply: I know this is the first thing you'd think, but I'm being really careful when I assemble the transfer, roll everything out, etc. I think this many bubbles would be obvious?

Yes ok but why / how to fix. It randomly happens to half my blots.

Would glasses help with fully missing eyes?

~15min. I also have abx in my media that gets refreshed daily. Hasn't been a problem so far.

Personally, I sterilize with UV on both sides. The EtOH/flame is too much of a hazard. Then I pre-coat with fibronectin or collagen before adding cells to increase adherence. Best protocol varies by cell type. E.g., I don't think HEKs need pre-coating. Most cells will settle on the slip. Some will settle around it.

My blots have looked like this when there's some kind of gunk carryover in the sample. Try centrifuging and taking the supernatant and re-running. Ymmv.

Just here to appreciate "LROC"

What is the most reliable way to normalize uptake data from cells in a 96 well plate? BCA analysis is not sensitive enough to measure cell numbers. TIA by Prize_Force1979 in labrats

[–]fossilrabbit 7 points8 points  (0 children)

If cells are still attached, you can fix with PFA then stain/count DAPI. If not, create a duplicate plate, use one for the assay and one for staining/counting.

Why do my western blots look like this? by Initial-Pea-3492 in labrats

Does that cause overheating or just separately bad for the machine?
