Immuno-precipitation/pull-down
GFP Tagging & Microscopy

SAGE
Principle is to convert every mRNA molecule into a short (10-14 base), unique tag. Equivalent to reducing all the people in a city into a telephone book with surnames
After creating the tags, these are assembled or concatenated into a long “list”
The list can be read using a DNA sequencer and the list compared to a database to ID genes or proteins and their frequency
