Speakers from NIST, SCB, and Nexcelom Bioscience break down and simplify the ISO Cell Counting Standards.

Watch the Webinar

The rapid advancements in cell and gene therapy products and development along with the expansion of industry partners and regulatory agencies, highlight the need for standards in cell counting and viability measurement assurances. Recently, ISO 20391-2:2019 Biotechnology — Cell counting – Part 2: Experimental design and statistical analysis to quantify counting method performance standards were published to guide the development of fit-for-purpose cell counting methods.

In this webinar, speakers will introduce ISO cell counting standards and how they fit into cell counting method development and selection. Additionally, we will describe the key cell counting success factors provided in ISO Cell Counting Standard Part 1 for improving the quality of cell counting results. Finally, we will describe the use of ISO Cell Counting Standard Part 2 in demonstrating experimental protocols for evaluating and comparing various cell counting methods to determine the quality of the cell counting measurement process.

Key Takeaways:

  1. Why companies should implement standards; specifically ISO Cell Counting Standards 20391, part 1 and 2
  2. Introduce the six key success factors to evaluate and compare different cell counting methods by establishing a multi-parameter analytical approach
  3. Demonstrate the fit-for-purpose analytical tools to develop and compare different cell counting methodologies
