Latest news: FlyAtlas2 : A Database web-app for fruitfly expression with added RNA & miRNA goodness ! Click here to visit the application. Read all about it here.


This dataset was generated by Venkat Chintapalli, Jing Wang & Julian Dow at the University of Glasgow with funding from the UK's BBSRC.
It gives you a quick answer to the question: where is my gene of interest expressed/enriched in the adult fly?
For each gene & tissue, you're given the mRNA SIGNAL (how abundant the mRNA is), the mRNA ENRICHMENT (compared to whole flies), and the Affymetrix PRESENT CALL (out of 4 arrays, how many times it was detectably expressed).

String to look for? (e.g. vha, cell adhesion, receptor, aquaporin, adenylate, CG1147, pnt)
