SYTOX™ Green Ready Flow™ Reagent is a bright, easy-to-use nucleic acid stain that helps to distinguish dead cells from live cells in flow cytometry assays. The dye can only enter cells that have lost membrane integrity and bind to DNA, acting as a counterstain when excited at 488 nm, with an emission peak of 523 nm. The reagent can be used with both mammalian and bacterial cells, and can be used in multiplex assays.FeaturesSta…

The Guava® Caspase 3/7 and 8 Assays employ a FLICA (Fluorescent Labeled Inhibitor of Caspases) reagent that specifically identifies active caspase 3 and 7 molecules or caspase 8 molecules. Non-cytotoxic, cell permeant dyes elimiate lysis and permeabilization procedures. Each FLICA is comprised of three subunits: A caspase-specific amino acid inhibitor containing a recognition sequence for caspase 3/7 (DEVD) or caspase 8 (LETD)…

High plex proteomics instrument for spatial biology

We offer extensive Antibody Functional Characterization Services, focusing on both Fab-based target binding and Fc-mediated effector functions. Our assays analyze mechanisms like Neutralization, ADCC, CDC, and ADCP, leveraging advanced platforms to select promising therapeutic candidates.

Microglia are the resident macrophages in the central nervous system (CNS). One of their most important characteristics is their ability to phagocytose, which plays a pivotal role in maintaining brain homeostasis and responding to neurodegenerative diseases. In vitro microglial phagocytosis assays assist in understanding how microglia maintain tissue homeostasis in healthy and disease states.

Live cell bacteria stains, suitable for flow cytometry or fluorescence microscopy. Stain live and dead, gram-positive and gram-negative bacteria with green or red fluorescence.

An extensive collection of recombinant Cluster of Differentiation (CD) proteins, which are key cell surface markers for immunophenotyping, immune function studies, and therapeutic targeting.

A two-color viability staining kit optimized specifically for gram-positive bacteria strains. Offers a simple 30-minute staining protocol, no wash required.

Kits to covalently label dead cells, allowing cells with permeable plasma membranes to be excluded from analysis in flow cytometry. A wide variety of dye options for standard flow, spectral flow, and fluorescence microscopy.

Annexin V fluorescent conjugates can be used to detect apoptotic cells. Annexin V is available conjugated to a wide variety of dyes.

A luciferase-based ATP cell viability assay offering high sensitivity, wide dynamic range, and long-lasting signal for high-throughput luminescence detection in microplates.

Fluorescent dyes optimized for staining endospores. The dyes also stain both live and dead bacteria of gram-positive and gram-negative strains. In B. subtilis, the dyes stain both vegetative cells and endospores and have been validated for detection by fluorescence microscopy and flow cytometry.

Highly-selective dead cell stains for bacteria cultures. The stains are suitable for both gram-positive and gram-negative strains.

Myelotracker® is a cutting-edge fluorescent probe that enables precise detection of neutrophils—essential immune cells—in both blood and tissue samples. It offers researchers a dependable tool for exploring inflammation, infections, and immune system activity.

A powerful technology platform for screening large libraries of antibodies, peptides, or protein domains displayed on phage to identify high-affinity binders against any target.
