challenge!

Nine panels of rat brain tissue of three treatment groups, stained with antibodies against 3 different proteins.

None of these panels are expected to overlap. Yet, two panels shown an overlap.

Which two?

@ElisabethBik

And people ask why referees don't spot image duplications... Even when announced, and having looked at a few in my time, I still couldn't find this one in 5 minutes of effort!

@ElisabethBik I would say c (lower left quadrant) and g (upper right quadrant)?

@irna Perfect! You have earned the first Emoji Award: 🏅
Congrats!

@ElisabethBik either 1 and 4 or 1 and 6 numbering 1 as the upper left and proceeding left to right and then resetting to the left in the next lowest row..
Whew, that took more words than I thought it would!

@mycotropic
The panels are labeled a through i, so that makes it easier 🙂
Assuming your answer is then panels a and d or a and f, unfortunately, that is not correct. Sorry!

@ElisabethBik I'm an epidemiologist and I've always sucked at lab stuff so I shall not dwell on my failure!
