title: [Application of BIOMED-2 primers in analysis of T-cell receptor gamma gene rearrangements in paraffin-embedded tissue specimens of T-cell lymphoma].
abstract: OBJECTIVE
  To evaluate the practical values of PCR detectable T-cell receptor (TCR) gene rearrangement in paraffin embedded tissue samples in the diagnosis of T-cell malignancies using BIOMED-2 PCR multiplex tubes TCRgamma(A+B).
  
  
  METHODS
  Traditional phenol-chloroform method was used to extract DNA from 55 cases of archival paraffin embedded tissues samples of T-cell malignancies and the DNA quality was evaluated by PCR-based amplification of housekeeping gene beta-globin. The selected BIOMED-2 PCR multiplex tubes TCRgamma(A+B) were used to detect TCR gene rearrangement and comparison with the results of universal TCR primers (T(VG)/T(JX)) was performed.
  
  
  RESULTS
  Positive detection rates by the BIOMED-2 multiplex tubes TCRgamma(A+B) and the universal primers (T(VG)/T(JX)) were 76.4% and 60.0%, respectively. There were not statistical difference between the methods (P > 0.05).
  
  
  CONCLUSIONS
  BIOMED-2 multiplex tubes TCRgamma(A+B) is suitable for detection of clonal rearrangements of TCR genes in current archival paraffin embedded tissue samples of T-cell malignancies.
