Quantitation of γ-H2AX Spots on the ImageStream

6 Feb 2011

This application note shows ImageStream methods for quantifying DSB foci using automated γ-H2AX and 53BP1 spot counting, both in tumor cell lines and in primary murine CD8+ T cells. We also show quantification of MDC and γ-H2AX colocalization at DSB foci following irradiation.

Image Stream®X Mark II Imaging Flow Cytometer

Merck

The revolutionary ImageStream®X Mark II Imaging Flow Cytometer combines the speed, sensitivity, and phenotyping abilities of flow cytometry with the detailed imagery and functional insights of microscopy. This unique combination enables a broad range of applications that would be impossible using either technique alone. This instrument produces multiple high-resolution images of every cell directly in flow, including brightfield and darkfield (SSC), and up to 10 fluorescent markers with sensitivity exceeding conventional flow cytometers. Compared to its predecessor, the new ImageStream®X Mark II Imaging Flow Cytometer offers a streamlined workflow, greater flexibility, and optimizations for rare cell applications. Taken together, the capabilities of the ImageStream®X Mark II make it superior for traditional flow applications while greatly expanding the scope of flow cytometry. Applications include the study of cell-cell interactions, phagocytosis, apoptosis and autophagy, the characterization of circulating tumor cells, and many others.

Cell / Tissue CultureCell culture or tissue culture is used to study the biology of cells or tissues and to isolate cellular products in an environment which can be manipulated and well defined. Accurately control your culture environment with bioreactors or culture incubators, bind your cells to a surface or together with an extracellular matrix. Distinguish cell types with differential media or proliferate cells with certain characteristics using selective media. Enrich your media with supplements such as growth factors, sera and vitamins.

There are many genomic technologies such as DNA sequencing of whole genomes, computational biology and bioinformatics. DNA and nucleic acids must be isolated and concentrated from cells for analysis with kits, automated analyzers and software. Other useful technologies for studying genomics include PCR, microarrays and electrophoresis.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.
