The VASP research-use-only assay protocol is simple. Small-volume citrated whole blood samples are used to measure intracellular platelet vasodilator-stimulated phosphoprotein, and as a no-wash assay, pre-treatment steps are not required. A flow cytometer measures the sample’s phosphorylation states, and acts as a biomarker for inhibited, activated or resting platelets, with two-color results in 30 minutes. The assay’s superior stability means that samples may be analyzed up to 48 hours after collection, allowing for research or reference lab analysis away from the facility where the blood was collected. Stago’s standardized flow cytometry-based VASP assays are an alternative to traditional functional assays such as platelet aggregometry, and offer increased accessibility and sensitivity for many cellular targets. Additionally, this method offers inter-laboratory and day-to-day reproducibility as well as positive and negative threshold determinations. Stago’s VASP flow cytometry assay kit is for research use only in the U.S. and Canada, and is not for use in diagnostic procedures.
