Researchers, antibody and assay developers, and IHC Labs often find it very difficult to find a reliable and verified source of positive/negative controls for their IHC experiments especially when they are developing new IHC protocols for novel targets whose expression pattern is not known or screening for new antibodies whose staining characteristics in IHC is not known.

Cytosections offer a verified, reproducible and renewable source of positive/negative controls where the expression of the target biomarker is confirmed for accuracy & specificity by an immunoassay.
