For all who are interested in the lowdown on Permeafix..... Ortho Diagnotic Systems is the company that developed Permeafix and from whom we have been purchasing this reagent for several years now. About 9 or 10 months ago I had heard a rumor that they were going to discontinue this product, which I found very disturbing. We have invested significant time and energy to develop and test Permeafix in our experimental protocols, and to have it suddenly withdrawn would have been extremely aggrevating. I knew that Ortho had already farmed out the actual manufacturing of Permeafix, so I had concerns about their commitment to this product. When I contacted them back then, I was told that the elimination of Permeafix was a remote possibility, and that they were sure that the product would be licensed to someone else if Ortho decided to completely stop being involved with Permeafix. After the message from Tonya, I telephoned the company, and sure enough the customer service rep said that they have discontinued it. I inquired further, and spoke with a representative who said that they currently are out of stock of Permeafix, but there is one batch currently undergoing QC, and it should be available in a couple of weeks. According to this rep, the company may or may not have another batch generated before the end of the year. They are supposedly in negotiations with some (unnamed) company that will pick up the whole manufacturing and marketing of Permeafix, but the time frame is very vague....it is likely to be no sooner than the end of the year. To say that I feel that Ortho has shown a very poor attitude towards the support of this product is putting it mildly. They are supposedly going to have someone contact me so that I can voice my concerns and (hopefully) get more information, so if I find out more I shall post it.
