Flow Cytometry / Cell Counting Products & Reviews

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

Ready-to-use kits providing optimized reagents and protocols for rapid, reliable, and reproducible detection and quantification of specific biological targets or activities.

Recombinant TNF superfamily ligands and receptors, pivotal for research into apoptosis, cell survival, inflammation, and immune regulation.

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.

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

The Cytoloader increases the throughput of your flow cytometer through the addition of a Hudson PlateCrane or Cyclops microplate handling robotic arm.

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.

The CF® dye TUNEL Assay Apoptosis Detection Kit label apoptotic cells in fixed tissue sections or cellular samples for fluorescence microscopy or flow cytometry.

Fixable cytoplasmic stains for monitoring cell division by flow cytometry. The dyes can also be used to track cell populations in co-culture.

Far-red, mitochondrial stain with excellent tolerance for fixation and permeabilization after staining.

CYTOQUBE is a Light-Sheet Microplate Cytometer that performs high-speed fluorescence imaging and analysis for both 2D and 3D cell-cultured samples. It is capable of scanning 1536, 384 and 96 well microplates, acquiring whole-well 3D fluorescence images.

Preservative-free Annexin V conjugates are compatible with real-time staining of apoptotic cells for live cell imaging, fluorescence microscopy, or flow cytometry.

The new standard for full spectrum flow cytometry

Near-IR Annexin V fluorescent conjugates can be used to detect apoptotic cells and are suitable for in vivo imaging.

Unmatched Single-Cell Analysis with Multiplexing Power

A Complete Solution for Functional Live Cell Assays Under Controlled Shear Flow—Great for Labs With an Existing Inverted Microscope

ToxCount™ provides a two wavelength cell viability assay based on determination of live and dead cells. The assay uses fluorescent dyes that measure permeability of the plasma membrane of dying cells and the ability of living cells to retain intracellular esterases, respectively. Live cells are distinguished by the presence of ubiquitous intracellular esterase activity, determined by the enzymatic conversion of the non fluores…
