Learn how UV radiation causes DNA mutations. Read about about the mechanisms that lead to skin cancer and the detrimental effects that UV light can have on our DNA-based experiments.
Do you know what each ingredient in cell culture media does? Read on to take a look at the common ingredients and break down their roles.
You may have heard about a breakthrough cancer therapy that engineers patient’s immune cells to fight their cancer using chimeric antigen receptor (CAR)-T cells. If you don’t live in the world of immunology, you may not know what a CAR is, or what it is used for. Here you’ll find a brief guide to CARs,…
Bacteria are the workhorses of many molecular biology laboratories, and mastering the basic techniques to manipulate bacteria is an important stepping-stone towards achieving great results. When isolating DNA from bacteria, it is important to start with a single colony to ensure a homogenous population of bacteria in your culture. Isolating a single bacterial colony from…
To many users, the flow cytometer is a magic box: put in cells, get out data. You click the button to tell it which colors to look at without much thought about how the machine does this. However, not all fluorophores are created equal—some configurations might exclude the spectrum you’re really looking for. Here’s a…
We have all been to awful talks—hours of slides crammed with data, given by presenters who assume you know as much as they do. But hopefully you’ve also seen a great scientific talk. A talk in which you’re walked through a story, eagerly anticipating each question and data point, until you finally reach a conclusion…
While you can observe mitotic cell cycle progression using immunofluorescence, flow cytometry is a great tool to delineate details that aren’t apparent by chromosomal morphology alone. DNA stains are a great way to get a general idea of what your cells are up to. There are also a number of other stains you can use…
Through many trials, and lots of error, I learned that there are many considerations for mass spectrometry that might not be obvious to you as a molecular biologist. Common contaminants, even in small quantities, can mask important peaks in your mass spec data and have a huge impact on the final results.
So you want to work with mouse B cells? Primary murine B cells are a difficult, yet fascinating system to work with and can help deepen your understanding of an immunological system. You can study many things with primary B cells, including: immune activation antibody production cell-cell interactions between immune cells and immune phenotype These…
