The Four Pillars of Achieving Accurate and Precise Cell Counts

Many biological science applications require an accurate, precise measurement of the number of cells and their viability prior to downstream analysis. This assessment can be done manually with a traditional hemocytometer and microscope or with an automated cell counter, such as the Invitrogen™ Countess™ II FL. Regardless of the chosen cell counting platform, achieving an accurate and precise count from repetitive counts of a single sample or across multiple samples is critical, yet sometimes challenging. This application note covers the four pillars of accurate and precise cell counting to minimize variability and maximize cell counting confidence.
