Identification of B Cells, NK Cells, Multiple T Cell Subsets and Myeloid Cells by 13-Parameter Immunophenotyping of Human Lysed Whole Blood

Identification of B Cells, NK Cells, Multiple T Cell Subsets and Myeloid Cells by 13-Parameter Immunophenotyping of Human Lysed Whole Blood

21 Oct 2015

Immunophenotyping is the analysis of heterogeneous populations of cells within human blood for the purpose of identifying the presence and proportions of various cell populations. This application note describes the use of the Attune NxT Flow Cytometer with 4 lasers and 13-color immunophenotyping analysis of stained human whole blood using a stain/lyse protocol. Lymphocyte, monocyte and granulocyte populations were distinguished with forward scatter (FSC) and side scatter (SSC); and monocyte, T cell, B cell and NK populations were identified using fluorescent antibodies against surface antigens specific for the different immunological populations.

Invitrogen™ Attune™ NxT Flow Cytometer

Thermo Fisher Scientific

The Invitrogen™ Attune™ NxT flow cytometer can be designed to accommodate the most common fluorophores and fluorescent proteins used in flow cytometry to match the panels you are currently running. Multiple fluorescent proteins can be detected with an optional 561 nm laser. Whether you configure your system now or upgrade later, the Attune NxT flow cytometer can grow with you and your research needs. The Attune NxT flow cytometer, designed using acoustic-assisted hydrodynamic focusing, achieves sample-throughput rates of of 12.5 µL/min–1 mL/min or 12.5–1,000 µL/min—up to 10 times faster than traditional hydrodynamic focusing systems and data acquisition speeds of 35,000 events/sec. Acoustic focusing allows significantly higher sample rates, which simplifies sample preparation, reduces protocol times, and minimizes cell loss. This feature is useful for no wash, no lyse immunophenotyping protocols using whole blood and for samples that are inherently low in concentration, including cerebrospinal fluid and stem cell preparations. Your next result relies on the ability of your experimental design and your instrument to deliver more—more data, more detail, and more throughput. The Attune NxT flow cytometer was designed to meet the demands of more complex experiments, offering reliable data, day after day, in a grow-with-you system.   Features & Benefits: Modular design—Multiple configurations available—field upgradable. Save time—10X faster speeds with no loss in data quality. Simplified sample prep—No wash, no lyse options, non-clogging fluidics. Enables unique applications—Complex protocols on a broad range of cell types and samples.

Cell Adhesion AssaysCell adhesion assays are used to quantitate attachment and analyze the molecular mechanisms for extracellular matrix adhesion, cell migration and sensitivity to inhibitors. Find the best cell adhesion assay equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays.

Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.MetabolomicsMetabolomics is the study of small metabolites (the intermediates and products of metabolism). It involves the identification and quantification of cellular metabolites using analytical technologies such as GC, HPLC, NMR, and LC/MS.ImmunophenotypingBlood AnalysisThe analysis of blood is vital for many areas of life sciences and forensic investigations. Blood samples can be tested for a number of different reasons such as diagnosis, glucose levels, cholesterol and drug testing.
