Nano particle detection

When equipped with a violet laser, the CytoFLEX can be set up to measure Side Scatter from 405nm for enhanced nanoparticle detection. Mie theory predicts that the scattering cross section of a particle, and thus its scattering intensity, depends on the wavelength of light, the angle of collection, and the size, shape, and refractive index of the particle. All other factors being equal, using a shorter illumination wavelength will result in an increase in scattering cross section, and thus more scattered light. The CytoFLEX offers light scattering parameter measurements from the 488nm laser light, and optionally from the 405nm laser to enhance small particle detection.

WEBINAR: Extracellular Vesicle Detection and Analysis via Flow Cytometry

Az elmúlt évtizedben megélénkült az érdeklődés a szekretált membrán vezikulák, összefoglaló néven  extracelluláris vezikulák (EV) iránt, hiszen EV szekréciót írtak le többek között hematológiai, kardiovaszkuláris, neurológiai és autoimmun kórképekben, valamint daganatos megbetegedésekben is. Az extracelluláris vezikulák tanulmányozásának egyik legfontosabb eszköze - a mikroszkópia mellett - a flow citometria, mindazok ellenére, hogy a hagyományos műszerekkel az EV populációnak csak kis része volt detektálható mérettartományú. A Beckman Coulter készülékekben alkalmazott új technológiai megoldásoknak köszönhetően - mint például az AstrioEQ sejtszorterben a speciális FSC detektálás, vagy az új CytoFLEX készülékben a Violet SSC - a citométerek és szorterek egyre inkább alkalmasak a szubcelluláris mérettartományú részecskék vizsgálatára. Az új eszközökkel elérhető ismeretek előrelépést hozhatnak a fent említett betegségek patogenezisének megértésében, emellett új diagnosztikai és terápiás lehetőségeket is teremthetnek, ezért a webinar témája nagy érdeklődésre tarthat számot.

The Unique Peristaltic Sample Delivery System of the CytoFLEX Analyzer Enables Optimized Measurements

Generation of fluorescent antibody or genetic labels to identify hormone and neurotransmitter receptoractivity can be difficult and time consuming. A useful alternative is recording physiological changes inresponse to agonist binding its cognate receptor, many of which are G-protein coupled. When an agonist binds a G-protein coupled receptor, it triggers a quick cascade of events that often results in a transient release of calcium from intracellular stores. Alterations in transient intracellular calcium ([Ca2+]i) levels have been used previously in flow cytometry to identify functional receptor expression in cellular subpopulations [2], here we show that peristaltic sample delivery of the new CytoFLEX analyzer is particularly well suited to agonist-based calcium studies. Using the ester based, green fluorescent calcium indicator, Fluo-4 AM (Life Technologies), [Ca2+]i changes were measured in HEK-293 cells in response to ATP stimulation. Simple plumbing modifications to the CytoFLEX allowed easier access to the sample tube for agonist application; further modifications were made to implement a “stop time” technique. By using response to agonist as our physiological criteria, we have fundamentally enabled receptor identification and conclusively demonstrated its functionality.


CytoFLEX Instrument Evaluation Using Biological Specimens

Evaluation of the Xitogen flow cytometer, by independent research flow cytometry laboratories and Beckman Coulter senior research and development scientists, was performed using flow cytometers equipped with 12 parameters and 9 fluorescent detectors. Instruments were equipped with the enhanced Side Scatter channel (VSSC) option. Evaluation of biological specimens included fresh human whole blood, human leukocyte control cells, and smaller cells and particles, such as RBCs, platelets, microbes, liposomes, and vesicles.


Set-Up Of The CytoFLEX For Extracellular Vesicle Measurement

The measurement and the characterization of Extracellular Vesicles (EV) have been of growing interest over the last 20 years. Flow cytometry instruments were not the most appropriate way to analyse these particles as the optical resolution of instruments was insufficient to detect particles below 250nm. However, the Beckman Coulter CytoFLEX* now offers the ability to measure EV down to at least 150nm and allows the detection of their cellular origin using up to 13 fluorescence parameters. Regardless of the technical improvements the set-up of the instrument is still a critical point and several requirements need to be met which are illustrated here.

Extracellular vesicles are a heterogeneous cell-derived particle population in a size range between 50nm to 1,000nm. There is a growing interest not only from academic research groups to determine EV in several fluids such as cell culture supernatant, in plasma samples or in whole blood but also in clinical research since it has been shown that the measurement of microparticles (MPs)1 might be of clinical relevance. The methods to identify EV are many and involve high speed centrifugation, Western blotting, proteomics, electron microscopy, imaging methods and flow cytometry. Methods for the detection of EV by flow cytometry have been developed in the last years and special attention has been paid to standardization protocols. Compared
with other methods, flow cytometry has the big advantage that EV can be detected as rare events, in high numbers and by antigens on the surface, which characterize their cellular origin.
