WebPMT Voltage Optimization. Typical flow cytometer instruments use photomultiplier tubes (PMTs) to detect the fluorescence in the samples. The initial signal (light hitting the detector) is amplified within the PMT to improve the sensitivity and resolution of the measurements. The final signal intensity shown in your data plots therefore depends ... WebTherefore, if one took a sample of Anti-CD3 antibodies conjugated with a fluorescent molecule (such as Fitc), one could use the sample to “stain” the T-cells within a sample. …

Flow cytometry is a powerful technique that can be used to detect and measure the properties of a population of cells or particles. When using a flow cytometer, a sample containing … See more After hydrodynamic focusing, each particle passes through one or more laser beams of focused light with each light source having a single wavelength ranging from ultraviolet to far red. Light scattering or fluorescence … See more Any time a particle passes through the interrogation point and generates a "signal," a pulse is generated in a detector. These pulses reflect … See more Fluorescence measurements taken at different wavelengths can provide quantitative and qualitative data about fluorophore-labeled cell surface receptors or intracellular … See more As the pulses are generated, their quantification is necessary for fluorescence signals to be displayed on plots, analyzed, and … See more WebCD4 FITC SSC-A Tregs 7.5% Tregs 7.5%.
