What is vi-cell xr cell viability analysis?

Cell viability analysis is a crucial step in many biological experiments that involve cell culture, such as drug screening, gene expression, cell proliferation and differentiation. Manual cell counting using a hemocytometer and trypan blue staining is a common method for determining cell concentration and viability, but it has several limitations such as human subjectivity, pipetting errors, dilution errors and low throughput.

Automated cell viability analyzers such as the Beckman Coulter Vi-CELL XR offer several advantages over manual cell counting. Some such advantages are stated below:

 - Higher accuracy and reproducibility by eliminating human bias and variability 

- Faster and more convenient workflow by reducing the time and labor required for sample preparation and counting 

- Lower cost and environmental impact by avoiding the use of disposable slides and reagents

- More applications and flexibility by enabling the analysis of different types of cells, including suspension, adherent and aggregated cells

The Beckman Vi-CELL XR is an automated cell viability analyzer built to maximize throughput, while minimizing sample to sample variation. The instrument makes use of image-based processing to capture images of live and dead cells using the basic standard Trypan Blue reference method that enables the user to maintain standard protocols. The 12-position continuous loading auto-sampler built into the Vi-Cell XR allows increased throughput while eliminating the inherent variability of the manual method. The images are then analyzed by software algorithms that count the number of cells based on predefined criteria. The results are displayed on a user-friendly interface that allows easy data export and storage.

The Vi-CELL XR's image based analysis provides the following advantages - 

• It simplifies and automates the determination of cell-viability and concentration in clinical research, biotechnology, biopharma and bioprocessing markets

• It offers simplified tracking of bioprocesses

• It offers automated application setup and complete walk away acquisition and analysis
