What is multiphoton microscopy?
Multiphoton microscopy is an advanced imaging technique that allows for deep tissue imaging with minimal photodamage.
How does the dual fluorescent transgenic mouse model work?
This model expresses two different fluorescent proteins, allowing for the visualization of multiple cellular components simultaneously.
What are the advantages of live imaging?
Live imaging provides real-time insights into dynamic biological processes, which is crucial for understanding cellular behavior.
What is second harmonic generation (SHG)?
SHG is a nonlinear optical process that allows for label-free imaging of collagen and other structures in tissues.
Why is temperature monitoring important during imaging?
Temperature monitoring ensures the well-being of the anesthetized mouse and maintains physiological conditions during imaging.
