psgurel – I’ve just spent most of my morning in lab meeting, and will spend my afternoon going to a few lectures. Presenting work and getting feedback is a critical part of science. Lab meetings are somewhat more informal sessions where the entire lab can get together and discuss specific details on members’ projects. It’s helpful for all involved in terms of troubleshooting, fine tuning direction of the research project, etc. It’s fun, but can also be somewhat tiring. Here’s my post lab meeting selfie 🙂
crestwind24 – This morning I came into lab very early to make sure I got all of my experiments done before heading to Philadelphia in the afternoon. One of the things I needed to do was run 4 PCR reactions and then image the products of the reactions using gel electrophoresis. Or more simply, I needed to make specific fragments of DNA from the C. elegans genome, and then make sure I made the correct DNA by looking at its size. When I visualized the PCR reactions separated by size on an agarose gel (top panel), I did not see the size DNA I was making with the PCR. Instead I saw a bunch of randomly sized bands and smears (hence my grumpy face when sitting at the gel imager, bottom left). Luckily, since I was in lab so early, I redid the PCR at a different temperature and got nice crisp bands at the exact size I expected (right bottom panel)!!! I love when molecular biology works!!!
