The flow cytometer that we have all grown to know and love may have only come into its own in the 1990’s, but who would have known that the first cell sorter was invented as early as the 1950’s? With the recent death of one of the key developers of fluorescence activated cell sorting (FACS),…
Studying immune cell activation allows scientists to understand the way the body mounts a response to a specific infection, autoimmune diseases, or cancer. This knowledge plays a direct role in developing more efficacious vaccines and therapies. When tasked with capturing information on immune cell activation, flow cytometry remains the gold standard due to its versatility,…
It strikes fear into the hearts of new cytometrists. Compensation. More fights have started over the proper way to compensate at meetings than anything else. This article will strive to shed some light on the principles of compensation, and equip you with the tools necessary to achieve compensation mastery for your research experiments. Compensation is…
After designing a multicolor flow cytometry panel and securing the necessary cells and reagents, the process of optimization of the panel can begin. The first step in that optimization is titration of your antibodies. In this process, following a standard protocol to be used in the final analysis, you stain a known amount of cells with…
A flow cytometer is a device used to illuminate objects and capture and quantitate light emitting from these objects. The “objects” are normally single cells dispersed in a medium, but could very well be polystyrene beads, cell fragments or debris, or even large molecules. So, What’s in the Box? Using your highly tuned powers of deduction, you…
Flow cytometry. Some people love it—most hate it—but all can agree that it is one of the most powerful analytical tools immunologists possess. Here’s a quick refresher: as the name suggests, flow cytometry measures the physical and chemical characteristics of cells. This is accomplished by fluorescently labeling cell surface markers/proteins using antibodies conjugated to fluorophores….
