How to Foster Lab Cooperation
Research isn’t easy. Not only do you deal with experimental failures and demanding supervisors, you also work with other lab members — people who are under the same pressures and stresses as you. Staff, postdocs, PhD students, and undergrads are often given bench space and a desk and encouraged to sort out the personal side…
The Three Ts of Introducing Foreign DNA: Transfection, Transduction, and Transformation
Introducing foreign DNA into bacterial or eukaryotic cells is a common molecular biology technique. Some of the terminology involved can be confusing: transformation, transfection and transduction. What do these words actually mean? To make matters worse, sometimes people use these terms interchangeably, resulting in confusion between colleagues and collaborating labs. Here then is your definitive guide…
Outsourcing Research: Should Your Experiment Spend Some Time Away from You?
As a researcher, it’s satisfying to manage your own projects and do the bench work yourself. After all, if you don’t have experience with a technique, you’re usually expected to figure it out (with or without direct supervision). In some situations, dealing with difficult molecular techniques is simply part of the job description. The scientific…
Viral Vector Production: Myths & Misconceptions
Viral vector production is a worthwhile skill that can be made even easier with a few tips and tricks. In general, transfection of multiple plasmids into a producer cell line results in infectious, non-replicative virus. However, it is important to ensure that your vector preparation is efficient, giving your experiments the best chance of success.…
AAV Production Part II: Virus Purification
In Part I of AAV Production, I described how to produce crude (non-purified) AAV. In this article, I am going to tell you how to purify that crude prep. Virus purification is usually done by gradient ultracentrifugation. Two common methods involve gradients made from increasing concentrations of cesium chloride or iodixanol. A cesium chloride prep…
