How To Train Your Personnel

ExCyte chooses to train people in flow cytometry because we know what it’s like to feel the pain of ruined experiments. No one enjoys wasting thousands of dollars on reagents and priceless amounts of instrument and personnel time. This is especially true when grant funding comes into play. No one wants to miss out on a grant simply because the technology is too complex to master alone in a vacuum.

How much time, money and resources are wasted by half-trained individuals trying to operate complex cytometers sold as pushbutton washing machines? Every vendor sells the dream that their instrument can be run by anyone. And to a point, this dream is true. Any monkey can be trained to push buttons in the proper sequence. And surely a thousand monkeys can get it right eventually.

For too many people, learning flow cytometry is like playing the game “Telephone.” Someone starts a story about how the instrument should be run, then they tell that story to someone else, who tells it to a third person, and so on. Eventually, the story bears no resemblance to the original. This is a subpar way to learn how to use a complex piece of equipment that costs hundreds of thousands of dollars, if not more.

Most flow cytometers, imaging cytometers, and related instruments require operators with a background of biology and the mechanics of how the instrument works, not to mention which software to use and how. Even instruments that can be run by Graduate students and other untrained personnel benefit from the oversight of a trained operator. And encouraging these students to learn more about the field of flow cytometry is important to their scientific growth.

There are some things a color chart can’t teach you. Once you progress above 4-color flow, there are several complex variables to contend with. For example:

1. Knowing the difference between Tri-Color, Cy5-Pe and CyChrome (hint – there isn’t one)

2. Knowing why your APC signal is down on first tube (hint – could be residual bleach)

3. Knowing why FMO controls are important

4. Understanding proper treatment of compensation controls

5. How to setup and identify the proper voltage settings

6. Knowing whether or not you should save and reuse compensation settings (hint – you shouldn’t)

Proper training avoids waste of resources, time, and energy. Stop passing stories down from monkey to monkey. Instead, start educating your personnel professionally. This will make your lab more productive and competitive in the long run. You will also gain the peace of mind that comes with knowing exactly what to do in any flow cytometry situation. Knowledge is power in this case. The power to succeed.

Optimizing Flow Cytometry Experiments - Part 2 How To Block Samples (Sample Blocking)

In my previous blog on  experimental optimization, we discussed the idea of identifying the best antibody concentration for staining the cells. We did this through a process called titration, which  focuses on finding the best signal-to-noise ratio at the lowest antibody concentration. In this blog we will deal with sample blocking As a reminder, there are two other major binding concerns with antibodies. The first is the specific binding of the Fc fragment of the antibody to the Fc Receptor expressed on some cells. This protein is critical for the process of destroying microbes or other cells that have been…

Over the next series of blog posts, we will explore the different aspects of optimizing a polychromatic flow cytometry panel. These steps range from figuring out the best voltage to use, which controls are critical for data interpretation, what quality control tools can be integrated into the assay; how to block cells, and more. This blog will focus on determining the optimal antibody concentration.  As a reminder about the antibody structure, a schematic of an antibody is shown below.  Figure 1: Schematic of an antibody. Figure from Wikipedia. The antibody is composed of two heavy chains and two light chains that…

2020 - A Year Turned Upside Down

By: Tim Bushnell, PhD

What an incredible year 2020 has been. It started off like any other year and bam SARS-CoV-2 (aka COVID 19) entered the equation, bringing chaos and havoc to the world. Things kept changing overnight as new rules and regulations popped up. Masking, quarantine, and flatten the curve became common words in the news. How we met, how we interacted changed almost overnight. Throughout all of this, as we look to 2021, there is hope and optimism. Multiple vaccines have been developed, building on years of research into the SARS-CoV virus, with some approved for human use, and others on the horizon.…

Brightness Is In The Eye Of The Detector - What To Consider When Designing Your Panel

Brightness Is In The Eye Of The Detector - What To Consider When Designing Your Panel

By: Tim Bushnell, PhD

The heart and soul of the flow cytometry experiment is the ‘panel.’ The unique combinations of antibodies, antigens, fluorochromes, and other reagents are central to identifying the cells of interest and extracting the data necessary to answer the question at hand. Designing the right panel for flow cytometry is essential for detecting different modalities. The more parameters that can be interrogated will yield more information about the target cells. Current instruments can measure as many as 40 different parameters simultaneously. This is exciting, as it allows for more complex questions to be studied. Panel design is also valuable for precious samples,…

When a researcher chooses to use flow cytometry to answer a scientific question, they first have to build a polychromatic panel that will take advantage of the power of the technology and experimental design. When we set up to use flow cytometry to answer a scientific question, we have to design a polychromatic panel that will allow us to identify the cells of interest – the target of the research.  To identify these cells, we need to build a panel that takes advantage of the relative brightness of the fluorochromes, the expression level of the different proteins on the cell,…

This Is How Full Spectrum Cytometry Works

This Is How Full Spectrum Cytometry Works

By: Tim Bushnell, PhD

There are 4 major ways to sort cells. The first way can use magnetic beads coupled to antibodies and pass the cells through a magnetic field. The labeled cells will stick, and the unlabeled cells will remain in the supernatant. The second way is to use some sort of mechanical force like a flapper or air stream that separates the target cells from the bulk population. The third way is the recently introduced microfluidics sorter, which uses microfluidics channels to isolate the target cells. The last method, which is the most common––based on Fuwyler’s work––is the electrostatic cell sorter. This…
