RegisterStock solution stability [Bioanalytics]
Dear Vishal,
The Crystal City white paper states that "if the reference standard is within its expiration date when the stock solution is prepared, there is no need to prepare a new stock solution when the reference standard expires". IMHO the same would apply to CCs and QCs prepared from that stock solution during the period for which you have demonstrated stability.
