What are Drosophila cell lines used for?
Drosophila cell lines are used in fundamental and biomedical research to study various biological processes.
How do you thaw Drosophila cell lines?
Thaw the frozen cells in room temperature medium and transfer them to a culture flask after mixing.
What is the purpose of cryopreservation?
Cryopreservation allows long-term storage of cell lines while maintaining their viability for future experiments.
How can cell density be assessed?
Cell density can be assessed using a hemocytometer to count viable cells in a suspension.
What is the role of trypsin in subculturing?
Trypsin is used to detach adherent cells from the culture surface for subculturing.
How often should Drosophila cell lines be passaged?
Fast-growing cell lines may need to be passaged up to twice a week, while slow-growing lines can be passaged every two weeks or longer.
