Path-plex (30 phosphoproteins)

90 samples/plate


The Path-Plex service allows relative quantitation of the phosphorylation levels of 30 phospho-proteins involved in major signaling pathways. This type of data can be used for pathway construction, monitor pathway alterations between disease states, identify patient-to-patient variability, or reveal cell- and drug-specific signalling pathway effects. See below "Supplementary Services" for more information and published work.

This type of assay has been optimized with specific lysis buffers in cultured cells and solid tissues. Please contact us to send you instructions on preparation of protein lysates as well as buffers to be used.


Samples can be delivered in micro centrifuge tubes or 96-well microtitre plates.

Delivery should be arranged in dry ice between Mon-Wed to ensure adequate receipt of samples.
