Wonder why so many lab solutions described as 10X, 25X, etc? What does it mean?
If you’re new to a lab environment, you may quickly notice that certain solutions aren’t described in terms of the absolute concentrations of their components. Rather, they might have something like 50X, 10X, 2X, etc written on them. What does that mean and why do people do it?...
Flow cytometry is a powerful technique to measure the properties of single cells and sort them into classes.
First developed in the 1960s and 1970s, flow cytometry is a technique that utilizes a specialized fluid system to continuously pull individual cells into a narrow fluid stream from a much larger solution containing thousands or millions of cells. This fluid-based separation allows one to measure various properties of individual cells which is useful to tease out different cell types within the same single sample. It should be noted that while flow cytometry is most commonly used to study cells, ...
