There is a lot of diseases coming to the forefront every day of the week. The deadly pandemic gave a setback to the people, and all of them were eagerly waiting for the development of a vaccine to fight the disease.

There is an increase in demand for flow cytometry, because of the growth in drug development all over the world. Apart from that, the demand of the same is increased because of a surge in research and development activities, and surge in acceptance of analytical instruments in clinical diagnostics. 

Due to all the above-mentioned reasons, the total demand for flow cytometry will reach to a value of over $10,065 million by 2030, all over the world.

Understanding the Technique of Flow Cytometry

Flow cytometry can be considered by some people as a rather “classical” technique, is still holds no less value in Immunology. The flow cytometry uses differ from identification of cells & categorization on the basis of membrane molecules, quantification of secreted and intracellular molecules, in addition to, more lately, examination in relation to exosomes. 

Here are some tips for improving the results of flow cytometry

Reduce Noise from Fluorescent signal

An important step all through the flow cytometry experiments optimization is reagent titration. This will be rather helpful for improving the specificity and strength of fluorescent signal despite the diminishing background.

Choose the Correct controls for Flow Cytometry

You should at all times comprise negative controls of the similar isotype as the labelled antibody so that it is possible for you to determine the degree of background signal in your experiments. Consist of cells acknowledged to express the antigen of interest since they will help a great deal to determine the specificity of the antibodies put to use.

Optimize Permeabilization and Fixation for Improving Detection

You should always make use of a freshly prepared solutions comprising of high purity paraformaldehyde for fixation and at the outset, just try mild detergents for permeabilization. For additional improvement, you can always surge the formaldehyde concentration slowly equal to 4% or try ethanol or methanol and with the use of other detergents as well as Triton X-100, or saponin short of fixation or alcohol fixation.

Stain Dead Cells for Obtaining Meaningful data from Viable Cells

Meanwhile dead cells are able to bind non-specifically to any antibody, it is very important to keep those out of the process of analysis. The finest way of doing this is with the use of a fluorescent dye that is able to pass through damaged plasma membranes and thus stain dead cells.

Keeping Fluorescent Signal at High Intensity

When you are performing the execution of staining of cell surface markers, at all times bear in mind the possibility that extracellular antigens can be adopted upon the blinding of an antibody. This phenomenon which is naturally occurring can have a considerable negative impact on the intensity of the fluorescent signal.
