Airflow and Flow Cytometry is an advanced laboratory procedure involving the sifting of cells and other biologic and nonbiologic materials and using lasers to assess and
measure their various physical and physical properties as they move through a liquid medium.
Basically, the lasers interact with the substances in the medium and produce a unique image and/or light emission pattern depending on how the laser actively interacts with the substance.
As a result, a distinct collection of signals is produced and numerous repercussions are noted. This information is subsequently processed for analysis purposes to find out the properties of the particles in the suspension.
How do airflow and flow cytometry technologies revolutionize cellular analysis, and what innovative applications can we expect in the future?
Numerous fields, including immunology, virology, molecular biology, cancer biology, and infectious disease surveillance, can make use of this adaptable instrument.
In medicine and diagnostics flow cytometry is broadly used since it is efficient in counting and characterizing important cellular populations, for instance, from living tissues such as tumors.
Select a cytometer and learn the setup of airflow and flow cytometry
In the case where there is access to more than one flow cytometer available in a core facility, it is advisable to speak with the core manager regarding what instruments would be ideal for the research that you intend to perform.
After deciding on the cytometer, one must learn the features of the instrument and how its configuration would influence the design of the experiment.
Make a Multicolor Experiment Panel for Yourself
Your panel must be equipped with antibodies against all markers of interest alongside the appropriate fluorochromes within your cytometer setup.
For cells with lower antigen expression, brighter fluorophores are more appropriate, while for antigens that are highly expressed dimmer fluorophores are more suitable.
More details need to be considered and care taken to avoid “spillover” or cross detection of fluorescence signals in the channels.
This is where our library of over 500,000 items as well as 550 fluorochrome from 60 leading manufacturers comes in handy by allowing the user to create, store and fine tune multicolor flow cytometry panels.
In addition, built-in Spectra Viewers and spillover tips machined to specific designs assist participants in unraveling the maze that is known as panel designing.
Enhance your protocol for staining
It is essential to accurately titrate all antibodies used in an experiment, as their volume should be appropriate for the specific experiment in question.
Be advised, working concentration ranges recommended for an individual antibody within a panel may not apply when other antibodies are present.
In addition, sufficient blocking serums have to be used to stop non-specific antibody binding.
Staining some intracellular antigens may also prove a challenge. Also and depending on the markers being looked at, fixative and or permeabilization solutions may be needed. It should be noted that fixation will destroy your cells.
Choose your controls
The most important instruments for every flow cytometry experiment designer are controls. To ascertain spillover into each channel, fluorescence minus one analysis is crucial.
This is particularly valid whenever there is an assessment of populations that are dim or indiscrete.
Read our article about Common Errors in Panel Design for more information on the flow cytometry controls.
Additionally, consider using a dump channel to save all of your controls and viability dyes.
Get your sample ready
Underprepared samples will yield incorrect readings and erroneous outcomes. All live cells must be suspended properly to eliminate clumps and stickiness and then sieved to separate dead cell debris which causes autofluorescence.
Naturally, careful handling of the cells is also necessary to avoid their mortality during the experiment. For more ideas on how to prepare samples, you may refer to our Essential Pre-Sort Checklist.
Conduct your tests
Make sure your samples are prepared for efficient processing before proceeding to your flow core, as the machine time of flow cytometers can be highly expensive.
In addition, when reserving a cytometer to use, always remember to include time for preparing for the experiment before and cleaning the instrument after.
Practice these suggestions for Getting More Out of Your Flow Core to make the most flow core time more efficient.
Perform data analysis of airflow and flow cytometry
Data from flow cytometry is analyzed on computer systems employing advanced algorithms.
There are several software options available, both free and paid, with unique functionality for data modification, representation, and sharing.
Some of those analysis software’s capabilities even include performing automatic compensation for fluorophore spillover. To see more of such software available, see our Flow Cytometry Analysis Software List.
FAQ’s
What is the crucial part of airflow and flow cytometry?
Using laser beam analysis, flow cytometry is a laboratory technique that defines the properties of suspended cells or particles.
The method has a wide range of applications in clinical settings for assessing bone marrow, peripheral blood, and other bodily fluid conditions.
Which application of flow cytometry is most predominantly utilized?
The most frequently conducted procedure on the cytometer is known as immunophenotyping.
This method in fact enumerates and characterizes cell populations in a complex mixture which is usually blood, bone marrow or lymph.
What is the Principal use of airflow and flow cytometry?
The ability to precisely count all or particular types of cells in the sample is the primary goal of microscopy, and more specifically flow cytometry.
What is the measurement unit of turbidity in airflow and flow cytometry?
Turbidity measurement is performed in soda centrifuge at low speed 5, 000 rpm for 10 minutes.
What are the benefits of using airflow and flow cytometry?
It enables the assessment of thousands of cells in a few seconds in a rapidly flowing concentrated single cell suspension.
This technique is employed in all the life sciences for simultaneous characterization of populations of cells by many parameters, while keeping the specimen untouched.
CONCLUSION
In summary, we have presented the theory behind airflow and flow cytometry and its practical use. Flow cytometry is being applied more and more not only in basic research but also in clinical laboratory science.
For example, there are additional flow cytometric applications such as DNA analysis, assessment of paroxysmal nocturnal hemoglobinuria (PNH), reticulocyte counts, and study and diagnosis of acute myeloid leukemias.
In addition to small bench-top flow cytometry units, currently available hematology cell counters also incorporate flow techniques into their group cell analysis.
