5 Muse Annexin V & Dead Cell Assay (MCH100105) Determines number and percentage of cells undergoing apoptosis (early apoptotic cells) by the binding of Annexin V-PE to phosphatidylserine, a membrane component translocated to the cell surface during apoptosis. Determines number of late apoptotic and dead cells based on loss of membrane integrity Inclusion of 7AAD in the assay allows for the detection of dead/late apoptotic cells with permeabilized membranes. Muse Annexin V & Dead Cell Reagent 5

6 Muse Cell Cycle Assay (MCH100106) Kit detects percentage of cells in various stages of cell cycle Propidium iodide intercalates into the base pairs of dsdna Fluorescent intensity of a stained cell is directly proportional to the DNA content of the cell, and consequently, reflects phase of cell cycle Muse Cell Cycle Reagent 6

7 Muse Caspase-3/7 Assay (MCH100108) Kit detects percentage and concentration of cells in various stages of apoptosis, based on Caspase-3/7 activity, in combination with a dead cell dye. Kit contains Caspase 3/7 Reagent which contains a DNA binding dye linked to a Caspase 3/7 substrate. When bound to DEVD substrate the dye s ability to electrostatically bind to DNA is inactivated. Cleavage by active caspases results in release of the dye and translocation to the nucleus Upon binding to DNA, dye becomes highly fluorescent Inclusion of 7AAD in the assay allows for the detection of dead/late apoptotic cells with permeabilized membranes.

23 Muse Human CD4 T Cell Kit (MIM100101) Detection and identification of lymphocytes and CD4 T lymphocytes in either whole blood or PBMCs using a simplified no-wash assay. The CD4 antibody identifies human helper/inducer CD4+ T cell (HLA Class II reactive) and recognizes a 60,000 Da surface antigen. Monocytes also express CD4 but at a lower density, and have no co-expression of the other antibodies present in the anti-lymphocyte cocktail; hence can be distinguished from CD4 T cells in this kit. The assay uses an anti-lymphocyte cocktail that identifies the lymphocyte population, and a CD4 antibody that binds to the CD4 cells.

29 SmartFlare RNA Detection Probes Detection on Muse Cell Analyzer SmartFlare RNA detection reagent is a novel probe capable of detecting specific mrnas and mirnas in live cells. This technology allows for carrier-free cellular endocytosis of the reagent, followed by detection and relative quantitative analysis of RNA levels in individual cells Each SmartFlare probe consists of a gold nanoparticle conjugated to multiple copies of a doublestranded oligonucleotide, in which one strand (the reporter strand ) bears a fluorophore that is quenched by its proximity to the gold core. When the nanoparticle comes into contact with its target RNA, the target RNA binds to its complementary capture strand and displaces the reporter strand. The reporter strand, whose Cy3 fluorophore is now unquenched, fluoresces and can be detected using the Muse Cell Analyzer. SmartFlare RNA detection probes conjugated with Cyanine (Cy3) fluorescent dye are optimized on the Muse Cell Analyzer. Data generated using the Muse provides the RNA expression levels of target genes and the percentage of expressing cells.
