When I keep PLTMax® in the fridge, I see particulate formation. What is going on?

PLTMax®stored at 4C can spontaneously develop precipitates over time. DON’T WORRY. These are clot like segments from the clotting factors present in human platelets. We have done our share of filtering them out, measuring active factors and come to the conclusion that these have no effect on PLTMax® function. We just pipette around them and suggest you should too.
