Figure Lengend Snippet: The staining intensity of a particular IHC method is influenced more by the biomarker than the choice of stainer. Data are shown as the CV (calculated as the SD divided by the mean) for the average OD within each staining run for each biomarker on a given instrument for all tissues. The box plots represent the distribution of the data, where the box defines the range encompassing values between the 25th and 75th quartiles, the line within the box is drawn at the median OD, and the whiskers demonstrate the expected variation in the data. Dots located over some boxes (eg, CD3 on instrument 0083) plot data that fell beyond the whiskers, which are indicative of staining runs with higher than expected variability. For Ki-67, the expanded ranges (longer boxes) on all 3 stainers denote that staining was more variable across runs for sections containing lymphoid tissue (see ). Instrument models: AutostainerPlus Link, Nos. 0010 and 0083; Autostainer Link 48, No. 0151. CV indicates coefficient of variation; DAB, 3,3′-diaminobenzidene; IHC, immunohistochemical; OD, optical density; SD, standard deviation.
