Abstract: Presented herein are methods of improving the consistency of staining with a counterstain. In some embodiments, the method makes use of an automated specimen processing apparatus or other staining device. In some embodiments, the staining methods are applied manually. In some embodiments, the counterstain includes eosin.

Abstract: The present disclosure is directed to specimen processing assemblies including (a) a lower plate (10), (b) an upper plate (30) complementary to the lower plate, and (c) a chamber formed therefrom. In some embodiments, the formed chamber is adapted to perform an unmasking operation, e.g. antigen retrieval and/or target retrieval. In some embodiments, the specimen processing assemblies are configured to maintain a specimen-bearing substrate (15) horizontal during all processing steps. The present disclosure is also directed to systems including one or more independently operable specimen processing assemblies.

Abstract: A closed-system flow cell system featuring an encasement with an inner cavity adapted to hold a slide and form a channel atop the slide. The encasement comprises a groove pattern within the channel, wherein the groove pattern provides a chaotic advection regime to fluid within the channel. The flow cell system helps enhance fluid mixing and prevent reagent evaporation and drying out of the tissue.
