If the first few slides here are confusing, remember, they're describing what the AKLecture explained. Feel free to pause and rewatch as needed, but this was the final piece I wanted to share. Certainly, in the Ars Technica article, on the industrial scale, the equipment you see in this video isn't what's being used. But the general idea is the same. So thanks to these videos and the Ars Technica article, you can now feel fairly confident that you have an idea what to do when you walk into the Biochem lab for protein purification. At the very least, you'll feel less overwhelmed by all the equipment, steps, and terms in front of you, now that you can comprehend the basic concept!
