Imagine that you want to test the efficiency of an antimicrobial treatment in inhibiting a certain bacterial pathogen. As part of the experiment, you expose the bacteria to the treatment and monitor the cultivability of the microorganism by counting the number of colony forming units (CFU) formed on culture media. If the microorganism is sensitive…
Fortunately for microscopy users, measuring intracellular fluorescence has been made relatively simple through an ImageJ plugin called the Cell Magic Wand. For those of you unfamiliar with ImageJ, it’s a popular image processing program that runs on Mac, Windows, and Linux. How to use ImageJ for measuring intracellular fluorescence First of all, to begin measuring…
If you want to know what is going on in the brain of drosophila you can use neurobiology imaging techniques to get a global whole-brain perspective. However, such techniques are slow compared to the rapid nature of the neuronal electrical activity, which may be better studied using Drosophila electrophysiology. Lab techniques are often shrouded in…
In this World of Microbes series, so far we’ve covered the importance of microbes in medicine including their use in vaccines, antibiotics, probiotics and protein production of antibodies for immunotherapy. Now we’ll diverge away from medicine and explore two other important fields where microbes are invaluable – food production and biofuel. Food Production When you…
If you are a plant biologist and working with the model plant Arabidopsis thaliana, undoubtedly you are a great fan of The Arabidopsis Information Resource (TAIR). You also probably order seeds/materials from the Arabidopsis Biological Resource Center (ABRC), or request them from fellow scientists. Of course, seeds are one of the basic materials you…
If you look at the composition of peripheral blood, using hematology microscopy, you’ll see that it’s composed of multiple different cell types, including monocytes. It’s possible to isolate these different components to study and experiment on them directly. So, if you’ve done a few experiments and had fun with THP-1 cells, you can move on…
