Evaluation of VWF Activity in Blood

An automated latex enhanced immunoassay (HemosiL, Diagnostica Stago, France) was used to determine VWF activity (VWF:Act). This assay is based on the ability of VWF to bind GPIb-α. Standard curves were prepared, and sample was added to the cuvettes required for the Compact Max (Diagnostica, Stago). At the same time, an immuneturbidimetric assay (LIATEST VWF:Ag, Diagnostica Stago, France) was performed according to the instructions of the manufacturer to determine the VWF Ag levels (VWF:Ag). The VWF:Act/VWF:Ag ratio was calculated and used to evaluate VWF activity.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
