What are supported planar bilayers?
Supported planar bilayers are lipid membranes that are anchored to a solid support, allowing for the study of molecular interactions.
How does TIRF microscopy work?
TIRF microscopy uses evanescent waves to illuminate only a thin region near the surface, providing high-resolution images of molecular interactions.
What is the significance of immunological synapses?
Immunological synapses are critical for communication between immune cells, influencing the immune response.
What role do cell adhesion proteins play?
Cell adhesion proteins facilitate the binding of cells to each other and to the extracellular matrix, essential for synapse formation.
Can these methods be applied to other areas of research?
Yes, the techniques can be adapted for studying various cellular interactions beyond immunology.
