On the photo on the left, you can see a gel on a low-fluorescent glass plate. This plate is in part in a tray that firmly holds it when the robot is doing its job. The holes everywhere result from the picking process but there are proteins everywhere and you can’t see them in visible light since they are labelled with fluorescent Cy dyes. You can see two white round stickers on each side of the gel: these are the picking references.
Here, the picker head is in the process of taking a part of the gel with some proteins inside. Exact positions were computed according to the fluorescent images, revealing the proteins. As you can see again: the gel is perfectly transparent for our non-bionic eyes.
Finally, you can see the spot picking robot in action. The picking head is moving following two axis thanks to the horizontal bar at the back and the perpendicular arm holding the picking head and camera. On the left, you have a pumping station: in addition to some jazz when the picking head is on the gel, the station is aspiring water through the head in order to help getting a plug out of the gel. After that the arm moves to the right of the photo where you have two 96-wells plates to collect samples. When the head is above a well, the pumping station is “blowing” water into the head in order to eject the plug into the well. Everything is under control of a computer and software that is on the right, outside of the camera angle.
This is the GE Healthcare “Typhoon 9400” scanner used to scan fluorescent gels. It’s a huge beast but it doesn’t make a lot of noise (well, I don’t want to stay the whole day next to it!). And this unit only has the red and green lasers inside. There is a second (smaller) unit below with only a blue laser source in it! You can see two gels ready to be scanned (the upper door has to be closed before!).
