What is live-cell imaging?
Live-cell imaging is a technique used to observe cellular processes in real-time without the need for fixation, allowing for dynamic analysis.
Why is fixation a problem in cell imaging?
Fixation can alter cellular structures and processes, leading to misinterpretation of data regarding drug delivery and cellular behavior.
How does this method improve drug delivery studies?
By allowing real-time observation, this method provides accurate insights into how drugs are taken up and distributed within living cells.
What are the key components of the imaging chamber?
The imaging chamber consists of a cover glass, a top part that screws onto the bottom, and a sterile coating to facilitate cell adhesion.
What role does temperature and CO2 play in cell imaging?
Maintaining optimal temperature and CO2 levels is crucial for cell viability and accurate imaging during long-term experiments.
