Thank you for your interest in Beckman Coulter CellProbe Reagents. You are correct in your observation that 26 of the original 38 CellProbe reagents have been discontinued. However, 12 CellProbe reagents remain for sale and are highlighted in our 2000 Cell Analysis Catalogue. As with every product discontinuation, a retrospective study is conducted and our results indicated that without specific applications, the market for certain CellProbes was not as large as initially thought. It was not due to the acquisition of Coulter Corporation by Beckman Instruments. Mara Neal Ends Marketing Manager Cytometry Reagents Beckman Coulter, Inc. =============================================================================== Christina, Upon first attempt the link you provided did not work for me. I origionally was going to respond to Virginia with information about CellProbe; but, when I looked the other day, I found a list of about ~25-30 of Coulter's CellProbe reagents on a DISCONTINUED PRODUCTS list. Could a rep from Beckman/Coulter please respond to this list with an explaination regarding why these reagents are being discontinued? Are all of the CellProbe reagents discontinued? Is it because of lack of sales? Does it have something to do with the Beckman takeover? I understand the reagents have been critisized because they are susceptable to non-specific protease (?aminopeptidase) attack. Can anyone comment about their experience with the non-specific protease lability? Does that have anything to do with their discontinuation? Curious in flowland...
