Amnis ImageStream MkII

The Amnis ImageStream^X MkII is a benchtop imaging flow cytometer system that combines the detailed cellular images and morphologic information of microscopy with the large sample size and phenotyping abilities of flow cytometry. The system has two CCD cameras, three lasers (Violet 405 nm, Blue 488 nm, Red 642 nm), and three imaging objectives (20x, 40x, 60x). The ImageStreamX MkII captures multiple images of each cell in flow, including brightfield, darkfield, and up to 10 fluorescent markers simultaneously. The image resolution depends on the magnification settings, with pixel sizes of 1 μm2, 0.25 μm2, and 0.1 μm2, respectively.

Data analysis is performed using the IDEAS software, which utilizes wizard-based and customized workflows to objectively quantify distinct cell populations, cellular features, and processes, including nuclear translocation, shape change, internalization, and apoptosis.

Applications include:

Intracellular co-localization
Nuclear translocation
Internalization and phagocytosis
Cell-cell interaction
Cell death and autophagy
Cell cycle and mitosis

When planning an imaging flow cytometry experiment and choosing fluorochromes, it is important to know the fluorochromes' specific excitation and emission wavelengths, as well as the lasers, filters, and detectors available on the instrument. Below is the information for the Amnis ImageStream^X MkII.

*It is important to remember that many fluorescent dyes are excited by more than one laser and fluoresce in multiple channels. It is very helpful to use a spectral viewer when planning an experiment.

** There are options to switch the Brightfield to different channels if needed (Ch1 & Ch9, Ch2 & Ch8, Ch 4 & Ch10, and Ch6 & Ch12).

Ideal fluorochromes for this instrument are AF488, PE, PE-TexasRed, SSC-Ch6, DAPI (or BV421), AF647, and APC-Cy7.
