Hermark assay
Witryna10 sty 2012 · The HERmark assay is able to measure a continuous distribution of HER-2 expression extending over a large dynamic range corresponding to approximately 25,000 to two million receptors/cell, based on a study of control breast cancer cell lines . Witryna28 cze 2010 · The HERmark assay is a quantitative assay that sensitively and reproducibly measures continuous H2T and H2D protein expression levels and therefore may have the potential to stratify patients more accurately with respect to response to HER2-targeted therapies than current methods which rely on semiquantitative protein …
