Excellent research takes time and effort, and a publication is your chance to showcase your hard work. While your main motivation might be to share and discuss your results, your methodology section is key to the reproducibility of your work, acting as a foundation for other researchers to repeat and build upon your findings. In…
As scientists, we are trained to design an experiment with the bigger picture in mind; the ultimate goals being to publish quality data and demonstrate scientific rigor. However, sometimes you need to focus on the little things, such as perfecting control and experimental samples, incubation times, and ordering reagents to truly ensure that you obtain…
I was so excited to start using 384-well plates for my assays. With so many wells, these plates are useful for testing many conditions in parallel, as required in ELISAs, siRNA library screens, and drug treatment dilutions. However, I quickly learned that pipetting in these plates is more complicated than I thought. This article contains…
Pipettes are not just fancy handlebars for your tips, they are essential for precisely measuring and dispensing liquids. These standard ‘tools of your trade’ enable you to accurately repeat experiments, validate results, make important comparisons between projects and eventually publish that outstanding paper. But there are a few pipette pitfalls. And they don’t just trap…
Working with anaerobic chambers is a unique skill set to have. It is only necessary if you are working with oxygen sensitive compounds. For example, some metallo-proteins require an oxygen free environment to stay in a reduced state, while others are sensitive and even reactive to oxygen. Sometimes working in anaerobic chambers requires a long…
If you’ve ever had backache from sitting at the microscope or biosafety cabinet, these tips may be useful for you!
The precision and accuracy of even the best calibrated pipette can be wiped out if you choose the wrong kind of tips. Depending on the experiment you are doing, the wrong kind of tips can also make your pipette a source of contamination, lead to waste of precious samples or reagents—or even cause you physical…
Sometimes working with a liquid handling machine seems a bit like wrangling a wild mustang—I know what I want it to do, but the software doesn’t work that way. That’s particularly true when working with 96-well plates. So, sometimes you have to think “outside the box.” Don’t limit yourself to what the manufacturer intended (but…
