Is this a series of independent observable entities that collectively tell the "story"? (Similar to the intent of the synoptic?)
For example:
Gene/protein target of stain
Antibody used (and clone)
Cytoplasma? Membraneous? Nuclear?
Distribution
Need to define the building blocks (legos) of the data on the slide. How the legos can be put together would need to be defined. And how much detail do the legos need to be defined.
