WebAug 21, 2024 · As a single cell technique, flow cytometry relies on identifying and excluding cell doublets and aggregates present in samples in the initial gating steps. This identification is based on detection of events generating electrical pulses falling outside of linear variations of pulse height, width, and area in a singlet population with increasing ... WebImaging can be used to confirm and adjust gates to include only single cells of interest. Here, an experienced user has gated singlets confidently. After evaluating the manual singlet gate, the CytPix image-derived parameter ParticleCount reveals this gate contains more than 4% aggregates.

WebForward versus side scatter (FSC vs SSC) gating is commonly used to identify cells of interest based on size and granularity (complexity). It is often suggested that forward … WebTraditional colony-forming assays take 10-14 days and are thus irrelevant when immediate assessment of HPC products, such as apheresis, is necessary. Flow cytometry is used to enumerate CD34+ HPCs to quickly determine the potency of a collected HPC product. However, these cells are rare events which may be masked by nonspecific or interfering ...
WebSep 15, 2024 · “Gating” refers to the selection of successive subpopulations of cells for analysis in flow cytometry. It is usually performed manually, based on expert knowledge of cell characteristics.... WebApr 8, 2024 · After washing with PBS, the protein expression in cells were detected by flow cytometry. To perform adhesion protein blockade, both cell types were preincubated with anti-CD44 or anti-ICAM-1 antibodies for 2 h at a dose of 2 mg/mL prior to flow cytometry analysis. The FACS gating strategies are shown in Supplementary Fig. 53b.
WebJurkat cells were incubated with 10 µM camptothecin for 4 hours at 37ºC to induce apoptosis. Samples were stained with Annexin V and PI and acquired on the Attune CytPix Flow Cytometer at 100 µL/minute. From the singlet population, gating strategies identified three cell subpopulations. WebA flow cytometer combines three systems to analyze single cells from a mixture ( 3 ): An optics system. A fluidics system. An electronics system. Cells are first resuspended in a pressurized buffer called sheath fluid …
