Technology
Kinases are the most intensively studied protein targets. We have developed a unique method to understand them. Our sensitive platform uses lysates obtained from only a few thousand cells or small amounts (2ug) of animal, xenografts or human tissues and cells to simultaneously determine the activity of all kinases present in these lysates.
This is accomplished by incubating the lysates across 196 to 144 tyrosine or serine/threonine kinase peptide substrates immobilized on the PamChip® microarray platform. Our 3D microarrays are spotted with peptides (i.e. phosphosites) that represent kinase targets. Kinases present in the lysates will phosphorylate the peptide substrates which are detected using fluorescently labelled antibodies. The phosphosites on the PamChips are human-derived and there is significant overlap with other organisms.
Based on current online knowledge, we compiled a comprehensive, integrated database (DB) of potential kinases that are linked to the peptides on the PamChips. This corresponds to ~350 unique kinases in literature, covering the majority of the kinome.
