We report here significant improvements to the assay that increases the sensitivity by two orders of magnitude, down to a single attomole of labeled target in a complex target mixture (for comparison, the detection limit of the Affymetrix microarray chip is about 15 amol per transcript).
In Li's lab, students manipulate the sub-nanolitre sample, such as the lysate of a single cell, using sophisticated, novel techniques developed in this lab, digest the proteins, and analyse the peptides through a highly sensitive mass spectrometer, capable of identifying less than 500 attomoles (1 attomole = [10.

The Agilent instrument is sensitive down to the attomole (one quintillionth, or 10 to the negative 18 power of a mole) range, and offers better than two parts-per-million mass accuracy, which gives scientists high confidence in their data and helps them easily identify the compounds they find.
