Flow cytometry is a laser-based technology employed in cell counting, cell sorting, biomarker detection, and protein engineering. Most commonly utilized in the Life Sciences, this application is now also used in microbiology, food quality control, plant and animal cytology, immunology, and other areas. This technology is used to analyze the physical and chemical characteristics of particles in a fluid as it passes through at least one laser. The fluorescence-labeled cell components are excited by the lasers to emit light at varying wavelengths. The fluorescence can then be measured to determine the amount and type of cells present in a sample. Up to thousands of particles per second can be analyzed as they pass through the liquid stream.
Flow Cytometry Based Applications
There are many different flow cytometry based applications. With multiple wavelengths at your disposal, allowing such diverse combinations as mentioned above, all of these applications are made more accessible. Some of these applications include cell sorting, immune cell phenotyping (immunophenotyping), immune cell function analysis, intracellular cytokine staining analysis, receptor occupancy analysis, gene therapy, cell cycle analysis, cell proliferation, membrane potential, live/dead bacteria discrimination, tumor suppressor gene/protein expression, antigen-specific cell responses, and many others.
Lasers and Flow Cytometry
RPMC has many years of experience supplying flow cytometry lasers, with a high-quality TEM00 beam profile, low noise, and high pointing stability and power stability to researchers, development teams, and various industry professionals dealing with flow cytometry applications. We offer the most common, critical wavelengths for flow cytometry, which you will find listed below. However, if you require another wavelength not listed, or have any other particular requirements, please do not hesitate to contact us or email us at firstname.lastname@example.org. We are able to provide a wide range of wavelengths, and we are always willing to try to accommodate any customization requests.
RPMC has secured trusted partnerships with a selection of leading manufactures who develop laser source products geared toward this application, allowing us to address a host of cost, size, and integration requirements. Because of this strategy, RPMC is able to provide a wide selection of CW laser diode and DPSS modules in a range of output powers, with cytometry-critical wavelengths, as well as multi-wavelength beam combiners, perfect for Life Science applications like flow cytometry. The most common flow cytometry wavelengths are 355 nm (ultraviolet), 405nm (violet), 488 nm (blue), 532nm (green), 552nm (green), 561 nm (green-yellow), and 640 nm (red). With all the available wavelengths, many unique color combinations are available for beam combination, allowing you to more easily switch out your samples and use different fluorescent markers. Furthermore, the use of multi-wavelength combiners reduces time and effort in re-aligning multiple sources to your microscope, as all wavelengths can be guided to the scope with an optical fiber. This means one alignment for multiple wavelengths.
As mentioned above, additional wavelengths are readily available upon request for specific, specialized applications. Most of the visible wavelengths can be used in flow cytometry, but it’s essential that all flow cytometry lasers have a high quality TEM00 beam profile. The recently developed ultraviolet fluorochromes, which are detection reagents, specifically for UV absorption, have brought UV lasers into the spotlight as a useful tool for Flow Cytometry. Lower profile, cost effective 349nm (UV) DPSS Lasers are a very practical replacement for older, bulkier, near-UV systems for ratiometric detection of the calcium ion Ca2+.High output power, power stability, low noise, excellent beam quality, and pointing stability are important requirements to consider when selecting a Flow Cytometry laser.
