Flow Cytometry / Cell Counting Products & Reviews

ArC Amine Reactive Compensation Bead Kit is a ready-to-use, bead-based compensation tool specifically optimized for use with LIVE/DEAD™ Fixable dead cell stain kits. The kit contains two components: the ArC reactive beads (Component A) bind any of the amine-reactive dyes and provide a positive signal; the ArC negative beads (Component B) have no reactivity and provide a negative compensation control. Results are analyzed by fl…

CountBright™ Absolute Counting Beads are a calibrated suspension of microspheres that are brightly fluorescent across a wide range from UV to 635 nm excitation wavelengths and 385-800 nm emission wavelengths. CountBright™ Absolute Counting Beads can be used to compare bead events to cell events using flow cytometry, allowing the absolute number of cells in a sample to be calculated. Cell counts are more accurate and less compl…

The Flow Cytometry Size Calibration Kit uses nonfluorescent particle-size calibration standards for a simple, accurate way to determine cell sizes by flow cytometry. The kit contains six suspensions of highly uniform polystyrene microspheres with different diameters: 1.0 µm, 2.0 µm, 4.0 µm, 6.0 µm, 10.0 µm and 15.0 µm. All of the microsphere suspensions are provided in convenient dropper vials.

The LIVE/DEAD BacLight Bacterial Viability and Counting Kit allows researchers to reliably distinguish and quantitate live and dead bacteria with the aid of a flow cytometer, even in a mixed population containing a range of bacterial types. This kit uses a mixture of two nucleic acid stains - green-fluorescent SYTO™ 9 dye and red-fluorescent propidium iodide - for viability determinations, and a calibrated suspension of micros…

The LIVE/DEAD FungaLight Yeast Viability Kit enables researchers to easily, reliably and quantitatively distinguish live and dead yeast in minutes by flow cytometry. The kit contains solutions of the SYTO™ 9 green-fluorescent nucleic acid stain and the red-fluorescent nucleic acid stain, propidium iodide. SYTO 9 stain generally labels all yeast in a population, with or without intact membranes. Propidium iodide penetrates only…

With no need for quenching and wash steps, the kit saves time and minimizes uncertainty over particle signals from internalized particles.The pHrodo Green S. aureus BioParticles assay provides sensitive detection without the need for quenching…

The LIVE/DEAD Fixable Blue Dead Cell Stain Kit provides the stable components to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining or prior to elimination of biohazardous materials using formaldehyde fixation. The amine-reactive LIVE/DEAD Fixable Blue Stain is an amine reactive dye that binds covalently to intracellular and extracellular amines in cells wit…

The LIVE/DEAD Fixable Violet Dead Cell Stain Kit provides the stable components to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining or prior to elimination of biohazardous materials using formaldehyde fixation. The amine-reactive LIVE/DEAD Fixable Violet Stain is an amine reactive dye that binds covalently to intracellular and extracellular amines in cells…

The LIVE/DEAD Fixable Aqua Dead Cell Stain Kit provides the stable components to determine the viability of cells prior to the fixation and permeabilization required for intracellular antibody staining or prior to elimination of biohazardous materials using formaldehyde fixation. The amine-reactive LIVE/DEAD Fixable Aqua Stain is an amine reactive dye that binds covalently to intracellular and extracellular amines in cells wit…
