Are you planning to do cellular immunology research? Then chances are you will be introduced to the flow cytometer – “a modern immunologist’s best friend.” This modern magic box is a highly versatile machine packed with cutting-edge fluidics and photonics (lasers). Combined with the monoclonal antibodies conjugated to fluorochromes capable of emitting light signals from a…
If you study human disease, you will likely handle a pre-analytical sample or two (or hundreds). For example, you could handle whole blood, serum or plasma, tissue biopsies, urine, fecal samples, cerebrospinal fluid, or synovial fluid—to name a few. You will probably use these samples to look for specific metabolites, proteins, or nucleic acids that provide…
A new lab toy to make it big in the last 5–10 years is the Accuri C6 cytometer (now under the BD umbrella), a low-cost instrument in comparison to the big boys. Lightweight, with a small footprint and straightforward maintenance, it’s often the cytometer of choice. It may be suitable for those labs that require…
While many scientists are methodical and precise, some of us like to live on the edge. Read a protocol all the way through? No thanks, I’ll take my chances and guess what concentration of HCl I should use. Label my tubes with the correct content? Puh-lease – it’s much more exciting deducing which is which…
A Spot of History Most of the biomedical methods used started as a curiosity. Then the one-off gains a limited use, the technology then progresses until its use becomes widespread. Just think about the arch from the curious polished glass spheres, used by Antony Levnhook to look at animalcules, to modern microscopes. The same story…
If there are a million cells of interest in your sample and you pass them through a sorter, you might expect to get a million cells back. But you don’t – and here is why. Hardware aborts A hardware abort occurs when an instrument can’t process the information about an event because it is still…
