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 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.

SYTO 9 stain generally labels all yeast in a population, with or without intact membranes. Propidium iodide penetrates only…

The LIVE/DEAD BacLight Bacterial Viability Kit for microscopy and quantitative assays provides a convenient and easy-to-use solution for monitoring the viability of bacterial populations based on the membrane integrity of the cell. Cells with a compromised membrane that are considered to be dead or dying will stain red, whereas cells with an intact membrane will stain green.
