![Analysis of Mass Spec data (dashed-line) of fractions stained with Cytokeratin 18 MS-QAVA™ monoclonal antibody [Clone: B23.1] (solid-line), reveals that less than 13.5% of signal is attributable to non-specific binding of anti-Cytokeratin 18 [Clone B23.1] to targets other than KRT18 protein. Even frequently cited antibodies have much greater non-specific interactions, averaging over 30%. Data in image is from analysis in A431, RT4 and MCF7 cells.](https://cdn-enquirebio.pressidium.com/wp-content/uploads/2017/10/enQuire-Bio-3875-MSM9-P1-anti-Cytokeratin-18-antibody-150x150.png)
