In the sci-fi novel Terminal World by Alistair Reynolds, a planet consists of zones with defined characteristics of matter interactions on a subatomic level. These conditions permit different levels of technology sophistication in various zones. For example, in the “Steamville zone” nothing more complicated than steam engines works – electronic schemes fuse irreversibly. Something like…
Welcome to the magical world of systematics! Looking for a way to produce a phylogenetic tree that’s a step above the default options, time efficient, not too program heavy and avoids using command line programs? Although there are more rigorous analyses that strict systematists perform, for your purposes, the following should suffice. 1. Data selection…
Supported lipid bilayers are a very useful tool in many fields of cell and membrane biology. But how easy is it to make them? Bilayers can be made quite reproducibly, once you have found a reliable protocol! However, it can take some time to optimize your technique, so to increase your chances, make sure you…
You may be familiar with standard single fragment ligations, but did you know you can ligate multiple fragments into your vector all at the same time! Discover how to perform multiple fragment ligation, including the different methods and troubleshooting tips for when things go wrong.
Here’s a tip that you may find useful if you are expressing proteins in E.coli using a lac promoter-based expression system, e.g. pET, in LB medium (L-broth). Lac expression systems are typically induced in the lab using IPTG (isopropyl-beta-D-thiogalacto- pyranoside), which is a non- hydrolyzable analog of lactose, the natural inducer of the lac operon….
