Quantification of Androgen Receptor (AR) splice variants in CTCs

Detection and quantification of Androgen Receptor (AR) splice variants of CTCs

in peripheral blood of prostate cancer patients

  • Splice variants: AR-V7, AR-567es, AR wild type, AR total
  • Methodology: multiplex RT-qPCR 
  • Instrumentation: LightCycler 2.0 (IVD, Roche Diagnostics)
  • Analytical characteristics: exceptional analytical sensitivity and specificity
  • Requested sample: 20mL peripheral blood (EDTA) - pre-, during or post-therapy
  • Cost: please contact Dr E.Lianidou (lianidou@chem.uoa.gr)
