What is the significance of using primary hepatocytes?
Primary hepatocytes are crucial for studying liver functions and conducting biochemical assays.
How many viable hepatocytes can be generated using this protocol?
The protocol can generate up to 100 million viable hepatocytes per preparation.
What is the cell viability rate achieved?
Cell viability rates between 88% and 96% are consistently achieved.
Why is a visual demonstration important?
Visual demonstrations help in understanding complex surgical and sterile techniques better than text alone.
What preparations are needed before starting the protocol?
