Dear Marc-- DPX is made by Fluka Inc.--their American branch is based in Ronkondoma NY. As far as I know, DPX isn't an anti-fading agent as such. However, there's relatively little fading with cy3 and cy5 staining mounted in it. Lemme know if there's anything else I can tell you-- As an aside: Nice job on the B-Max! It's a huge improvement over the old BH-2 based fluorescent illuminator. Brighter, better filter changer, less chromatic aberration in the condensor...the engineers covered nearly everything. Good work! Martin Wessendorf
