Matched Pair cDNA

At BioChain, our Matched Pair cDNA is prepared from premium RNA that is free of genomic DNA to ensure high quality. This product is a useful tool for accelerating gene expression analysis by identifying tumor-specific genes and tumor metastatic genes.

BioChain's human cDNA matched pair products include:

  • Primary Tumor and Normal Pair (PP); genomic DNAs isolated from the primary tumor and its adjacent normal tissue
  • Primary and Metastatic Pair (PM); consists of genomic DNAs from the primary tumor and corresponding metastatic tumor
  • Custom extractions are available


  • Ready to use for PCR quantification of gene expression
  • Identification of tissue-specific expression of target genes
  • Analysis of gene expression in rare tissues
  • Verification of genetic mutation
  • Comparison of a specific gene between different tissues


  • In-situ hybridization (ISH)
  • Fluorescence in-situ hybridization (FISH)
  • Library construction for NGS applications
