About us / Contact

Behind Mark53 lies a Vienna-based company that was founded at the start of 2013.
The company’s strategic direction lies in making a precise, standardised p53 gene test available in the form of the Mark53® analysis, which established the prerequisites for the routine clinical application of the predictive biomarker.

The assumption is that the p53 gene can be employed as a predictive marker, based upon clinical studies conducted at the Medical University of Vienna , headed by Univ. Prof. Dr. Daniela Kandioler. In these studies, the connection between the response to a standard chemotherapy and the p53 gene status were examined in different cancer types.

We look forward to hearing from you and to getting to know you in person!
