Ristocetin

The ristocetin-induced platelet aggregation (RIPA) is an ex vivo assay for live platelet function. It measures platelet aggregation with the help of von Willebrand factor (vWF) and exogenous antibiotic ristocetin added in a graded fashion.[1] It is similar to the ristocetin cofactor assay but has the added benefit in that it helps in the.

Platelet aggregation in whole blood

Platelet aggregation in whole blood. This assay measures platelet aggregation in whole blood as a decrease in the number of single platelets and is particularly sensitive to platelet micro-aggregate formation. We have used this assay extensively in pre-clinical and early clinical studies to characterise the mode of action of various compounds.

What is Platelet Aggregation? (with pictures)

 · Platelet aggregation is the clustering together of thrombocytes, which are the small, cell-like structures made in the bone marrow that help prevent bleeding. This clumping can occur in response to many different agents, including the nucleotide ….

Shear

The inhibition study revealed that the reduction in platelet aggregation size and HWM vWF multimers were mainly associated with ADAMTS13. In conclusion, the threshold of shear rate must not exceed > s -1 in order to maintain the optimal size of platelet aggregates to "plug off" ….

A novel flow cytometry-based platelet aggregation assay …

 · For this reason, the analysis of thrombocytopenic patients, infants, and animal models is problematic. We have developed a novel flow cytometry test of platelet aggregation, in which 10- to 25-fold lower platelet counts or sample volumes can be used, either of platelet-rich plasma or whole blood from human subjects or mice.

Helena Biosciences :: Why Perform Platelet Aggregation

 · Integrin AlphaIIbBeta3 is the most abundant platelet receptor, with 40 000 to 80 000 copies per resting platelet, acting as a major receptor for fibrinogen and other adhesive molecules (Wagner et al. ). Activation of AlphaIIbBeta3 enhances adhesion and leads to platelet-platelet interactions, and thus aggregation (Philips et al. ).
