Webto break cell-cell adhesion, you have to interfere with cadherin-mediated cell-cell adhesion. In the presence of calcium, these molecules are resistant to trypsin. If you remove calcium, by chelating it with EDTA, the cadherins become susceptible to trypsin, and you can get single cells. I agree that anti-fungals are best omitted if possible ... WebTrypsin and cell trypsinization. Trypsin, a proteolytic enzyme, is the standard way to detach adherent cell cultures and monolayers. This globular, pancreatic protease cleaves at the C-terminal side of lysine and arginine, breaking down vessel-adhering proteins and allowing easy resuspension during cell harvesting.
