STORM Microscopy Operation

8

Adjust the power of the activation laser, if necessary,
during real time analysis (preview) of the acquired
images.

Image acquisition is started. The result of real time
analysis (preview) and a graph are displayed.

Recommended number of bright points

The recommended data for STORM analysis is as
follows: the density of bright points is not too low but not
so high that they do not overlap each other. For
example, a structure that covers the entire screen (such
as a microtubule in a cell) should be provided with about
100 to 200 bright points per frame in a visual field with
256 x 256 pixels. The number of bright points to be
activated can be adjusted by changing the power of the
activation laser.

Real time analysis (preview) screen during image acquisition

Details of real time analysis

During real time analysis, the value of [Minimum Height] on the N-STORM control window is used as a threshold to
analyze bright points. Real time analysis does not include drift correction.

Graphic screen during image acquisition
