When you first start out using a microscope, you might only adjust the eye pieces, objectives, and the focus controls. However, you shouldn’t overlook the microscope condensers as they are an important part of the whole optical system of a microscope.
Northern and Southern blotting are now a thing of the past. They’ve been replaced with a faster and more quantitative technique. No longer do we wait days to know whether a gene is expressed. We can have the answer in 45 minutes! Real-time PCR is now commonly employed in almost all molecular biology laboratories to…
In the 30 odd years since its invention, the polymerase chain reaction (PCR) has become the bread and butter technique of molecular biologists. The secret to its indispensability lies in its simplicity and versatility. Numerous variants of the technique have been developed; one of these, real-time PCR, has become the method of choice for quantitative…
A Brief History of Detecting Amplicons The Old Days of Ethidium Bromide In the early 1990s, quantitative (q) PCR was in its infancy, and despite PCR itself already being around for 10 years, there were no easy ways of precisely quantifying the amount of DNA that was amplified in a PCR reaction. In those days PCR…
Mass Cytometry is a relatively new technology which has recently featured in many high-impact journals. You may have read about instruments including the CyTOF, CyTOF2, and more recently, the Helios. With these instruments becoming more widespread, you might find yourself asking, what is mass cytometry, and what can it do for you? The Basis: Conventional…
Stimulation of cells/tissue with a given stimulus (e.g., a cytokine) is a common experimental setup in any cell biology lab. The cellular response to the external stimulus e.g., the activation/deactivation of intracellular signaling pathways and/or the secretion of proteins is often the research goal, and there are a number of different methods that you can use to analyze such…
