Ever wonder what those small colonies, like satellites, surrounding a larger E. coli colony on your LB with ampicillin plates were? Or why, when you picked that colony, it never had the plasmid you just transformed? Well, it’s because those satellite colonies are “protected” from the ampicillin by the big colony. Read on for more… Ampicillin…
I often wonder why it is that molecular biology researchers stubbornly refuse to change 40-year old methods that, while work, are not as good as newer, faster and cheaper methods out there. I suppose rational scientists often have irrational superstitions. One example of an old method that could be improved is the growth media used…
You have probably run a standard agarose gel hundreds of times. They are great for visualizing small DNA fragments up to 10 kb, but what if you want to examine really large pieces of DNA or even whole chromosomes? This is where pulsed field gel electrophoresis (PFGE) comes in! While the equipment required to run…
Scientists today depend heavily on many molecular biology techniques to perform their research. For example, with the advent of next generation sequencing (NGS): scientists are able to look at very minute details, right down to individual genetic sequence variations. However, the increase in experimental complexity means that every extra step becomes more crucial than…
Overnight ligations are inconvenient — especially when they fail. Luckily, there’s a straightforward way to faster DNA ligations. This article highlights the secret ingredient to faster ligation reactions and offers some tips and caveats on its use. For a general overview of DNA ligations, see here and here.
