Platelet activation markers

Platelet activation markers

Following activation platelets release the content of their granules and several markers become expressed on their membrane, which can be assessed by flow cytometry. P-selectin (CD62p) is a well-established, commonly used marker for measuring platelet activation; our scientists have extensive experience assessing platelet function using this approach.

Samples are fixed after stimulation and the analysis of P-selectin expression can be performed at a later stage. This is an end-point assay and a very small volume of whole blood is required to run this test, which makes this approach a desirable high-throughput platelet assay if multiple compounds/conditions need to be assessed.
