Path-Plex

Path-plex (33 phosphoproteins)

90 samples/plate

SERVICE INFO

Protavio’s Path-Plex panel provides quantitative information on the phosphorylation of 33 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.

SAMPLE INFO

This type of assay has been optimised with specific lysis buffers in cultured cells. Please contact us to send you instructions on how to plate cells, what is the optimal cell density and protein concentration, as well as buffers to be used. Other sample types are also possible including solid tissue extracts and tissue cryo-sections but please contact as for more details.

SHIPPING INFO

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

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