Some of our stains are very old also, about 10 years ago we wrote on a label on each stain; Opened prior to: with that days date and Stable. We were CAP inspected many times after that and we had no problems. Just as you would label your reagents you make up as Stable when there isn't an expiration time period.

All of our reconsituted reagents which are in use were dated with an expiration date properly though. I have always assumed, perhaphs incorrectly, that powdered stains never expire. We have powders like Luxol Echt Blau, etc. that were purchased and opened over 40 years ago. If so, then these powdered reagents have gone through CAP inspections since the beginning and this inspector was the first one to find this problem. Is this one that we might protest? -- Patrick Laurie HT(ASCP)QIHC CellNetix Pathology & Laboratories 1124 Columbia Street, Suite 200 Seattle, WA 98104 PH: 206-215-5949 plau...@cellnetix.com _______________________________________________ Histonet mailing list Histonet@lists.utsouthwestern.edu http://lists.utsouthwestern.edu/mailman/listinfo/histonet -------------------------------------------------------------------------- Disclaimer: This electronic message may contain information that is Proprietary, Confidential, or legally privileged or protected.
