Basically, you choose a gel based on two main factors: how high you need the resolution to be and what is in your samples. To make the choice simpler, I made a handy chart describing the differences between them.
*Pulsed field electrophoresis is a technique in which the direction of current flow in the electrophoresis chamber is periodically altered. This allows fractionation of pieces of DNA ranging from 50, 000-5 millon bp.
Use this chart to help you understand the differences between the two gel types and your samples will be running like athletes in no time!

A lot of chemical reagents are relatively non-hazardous.But there are just as many that are extremely hazardous, which means you’ll want to take precautions to reduce any risk of exposure, repeated exposure, and of course, accidental contamination of anything – or anyone – that walks out of the lab at the end of the day….
Once upon a time, I thought reproducible research meant if someone else showed X in a paper, then I should be able to get X in my experiment. However, this actually refers to replication, an important but separate concept. Reproducible research is data analysis that starts with the raw data and arrives at the same…
Although bench work is an integral part of becoming a successful scientist, it is by no means the only part of it. It is often the uncredited skill set possessed by many seasoned scientists that make them so valuable to employers and to further research. In this article I will highlight the less obvious skills…
The more experienced hands in your lab know that molecular biology is rarely just a journey from A to B. As a result, I’ve constructed this short workflow as an introduction to genomic molecular techniques.
If you are working in a scientific laboratory, it is very important to be aware of the various types of water available, because the purity may not be acceptable for your specific experimental application. In most labs, there are generally two types of water piped in to the sinks: Industrial Water Industrial water is non-potable…
It seems like every movie that needs a shot of a scientist doing their sciencey-thing either gets the person to pour one pretty liquid from one flask into another or to stare intensely at a test tube with a look of knowing so much more than you ever could. Another favorite shot is of someone…
