• Cancer biomarker - detectable by blood test - could improve prostate cancer detection

  A new study supports the use of a DNA-based "biomarker" blood test as a complement to the prostate-specific antigen (PSA) test currently offered to screen men for prostate cancer. University of Cincinnati (UC) researchers report their findings online ahead of print in the British Journal of Cancer.R more

• Metamark Genetics Partners with Definiens on Tissue-Based Cancer Diagnostics

  Metamark Genetics, a privately-held oncology molecular diagnostic company, and Definiens announced a development and commercialization partnership in which Metamark will combine its proprietary multiplex protein detection platform with image analysis technology developed jointly with Definiens to de more

• Germ-killing sanitizers could have effect on alcohol tests

  Slathering on alcohol-based hand sanitizer every few minutes may have one unintended consequence — a positive screen for alcohol use in certain types of tests, a University of Florida study confirmed.But UF researchers also uncovered a potential biomarker that could allow tests to differentiate betw more

• High sensitive detection of follistatin by Imperacer®: an initial study on the way to analytical gene-doping tests
  

  For the understanding of interactions in the muscle-growth directing myostatin-pathway and therefore also for the establishment of high sensitive detection strategies for gene-doping, detailed studies of protein concentration levels in biological matrices and appropriate highly sensitive analytic techniques for quantitative monitoring of these biomarkers are required. In this work, the development of a high sensitive assay for follistatin based on the Imperacer® technology is described. The quantification limit in human serum was found at 60 pg/ml in only 6 µl sample volume. With this initial assay we demonstrate the first application in a set of analytical tests for a high sensitive myostatin pathway related profiling. more
