How to count cells using a hemocytometer
View these simple step-by-step instructions for counting cells using a hemoctyometer and microscope. Includes the formula for calculating the dilution factor.
Is your trypan blue rupturing dead or dying immune cells leading to an over-estimation of cell viability?
It is important for biologists to select the most accurate cell counting method that is fit-for-purpose, especially for cellular therapy products such as CAR T, where cell number and viability significantly affect treatment efficacy.
Identify & Resolve Manual Cell Counting Errors through Automation
The use of modern automation has largely eliminated many of the hemocytometer's sources of error, increasing the accuracy and efficiency of cell counting today.

Novel Fluorescent Viability and Vitality Detection Method for Ale and Lager Yeast Fermentation using Cellometer Vision
It's White Paper Wednesday! Read our featured white paper: Novel Fluorescent Viability and Vitality Detection Method for Ale and Lager Yeast Fermentation using Cellometer Vision Automated cell counting methods can monitor yeast concentration and viability throughout fermentation to ascertain cell health and the amount of yeast to be pitched or repitched, all of which contributes to the quality and flavor consistency of the final product [1,2,3]. Analyzing physiological and metabolic characteristics of the yeast cells permits operators to efficiently monitor yeast viability and vitality for quality control purposes, which impacts long-term storage and other physiological stresses.

A Novel NK Cell-Mediated Cytotoxicity Detection Method Using the Cellometer Vision
It's White Paper Wednesday! Read our featured white paper: A Novel NK Cell-Mediated Cytotoxicity Detection Method Using the Cellometer Vision As part of the innate immune system, natural killer (NK) cells are the primary form of defense against tumor cells and assorted pathogens [1]. A minor subset of NK cells (CD56brightCD16-) influence immune regulation via the secretion of cytokines interferon-γ and TNF-α [2]. The major subset of NK cells (CD56dimCD16+), however, directly lyse their targets [3]. Consequently, understanding the cytolytic functions of NK cells are key to understanding NK cell biology and function in adoptive immunotherapy. Download our white [...]
