[Histonet] pH of Roche Reaction Buffer

[Pairan, Kelly]

Good Morning,
How are you pHing the reaction buffer for the Ventana Benchmark Ultra?  Roche doesn't have a published pH for diluted reaction buffer.  CAP requirement ANP.22500 states that pH must be tested when a new batch is prepared or received.  Are you testing the reaction buffer after you dilute the concentrate (ie: preparing a new batch)?

Thanks,
Kelly
