...ool. Unfortunately, current technology is neither accurate nor sensitive enough to detect most of these proteins, which often exist only in trace amounts. A new liquid-phase protein separation technology under development at the U-M could help scientists solve the proteomics puzzle.

However, the programs were less accurate in defining the exact boundaries of the genes within the code, and groups that attempted to find elements controlling gene activity (e.g., promoters) made a large number of false predictions.
