RETRACTED: EPCA-2: A Highly Specific Serum Marker for Prostate Cancer

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the authors. They believe that the article contains findings that may be unreliable. As the authors re-reviewed the data points presented in the article, they identified differences between some of the plate reader values and those that were reported in the article. For some of the duplicates run, one of the values was indeed from the plate reader data, whereas the source of the counterpart value is not easily apparent. Therefore, because the authors could not replicate some of the counterpoint values, they cannot state if the data points represent the actual data generated in the experiments described. Furthermore, the duplicate values may not have been handled in the manner described within the Materials and Methods section of the paper and the values were not blanked. Taken together, the inconsistencies in validating the data collection and recordation warrant retraction of the article. The authors sincerely apologize for any inconvenience this might cause.
