Hello and a happy new year, I have a question about the expressed sequence tags (EST). I'm given a specific gene with its name, aminoacid sequence and nucleotide sequence and I need the expression frequency of the linked EST's. Is there a database that gives informations about the EST expression frequencies? The genes are from the algea Chlamydomonas. Maybe somebody has an idea how to solve this problem. Greetings, Bello
