Hi All, Steve is correct, the Ortho product in the States (specifically North America) is a gel product very similar to the Diamed (now Biorad) product, but in the rest of the world their product is Biovue which is entirely different, it uses a glass bead filter instead of the gel filter as used in the other products. The methodology is different also with different volumes of plasma and different centrifugation times (Biovue has a shorter 5 minute spin). It is my understanding that the 0.8% cells supplied in NA by Ortho are also formulated differently from those that are used in the Biovue system. Hope this clears up some of the confusion between posts from different parts of the world.
