Collagenase Selection & Process Optimization for High Yield Hepatocyte Isolation

Presented by 
Dr. Rafal P. Witek

This webinar will review best practices for building a high-yield primary human and animal hepatocyte isolation process with the inclusion of collagenase selection and buffer optimization. The webinar will cover process variabilities that impact isolation and how to overcome them to generate high-quality and high-viability hepatocytes. The information presented will enable participants to build their isolation, resulting in a high success rate and hepatocyte yield.
