he VenaFluxTM Platform is the first semi-automated microfluidic platform capable of executing cell rolling, binding/adhesion and migration studies under shear flow mimicking in vivo flow rates.  

Features:

• Robust and easy to use
• Ideal for use with whole blood for plaet adhesion, aggregation and thrombi formation (thrombosis); biofilm culture ove extended periods of time.
• Easy to study cell adhesion, migration and transmigration - more physiologically relevant than static assays.
• Excellent platform for in vitro studies and running experiments in parallel with animal models.

 

Applications:  

• Functional cell-ligand and cell-cell interaction studies.
• Morphology analysis of cell adhesion and migration.
• Tracking of flowing, rolling and migrating cells.
• IC50 curves easily produced.
• Preclinical drug development and lead optimization.
