RE: [Histonet] Ventana Benchmark Reagents

From:"Cindy Robinson"

The expiration on CC2 is 3 months at the longest in my experience.  I received some reagents which were outside the guaranteed outdate lengths....NeuVis nuclear stain which is supposed to have a minimum of six months use after receipt date and I had from 4 weeks to 3 months.  I called Ventana and got credit for these reagents.  Ventana can give you a list with the guaranteed lengths of outdate from the receive date.

originally the expiration interval was a year. the next shipment was down to
6 months.  contacted ventana and they say that they make "no guarantee on
the life of the reagent"??? if you look at the msds,  there's nothing in
there that would expire anyway, at least not reported at any significant
concentration.  BTW the reagent was cc2
