Matched Pair gDNA

BioChain's matched paired gDNA samples are unique in the market, which are prepared from the same donor. This product line is designed for identifying tumor-specific genes and tumor metastatic genes.

BioChain's human genomic DNA 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


  • Identify tumor-specific mutations
  • Discover tumor-related epigenetic modifications
  • Library construction for NGS applications

Quality Control

  • The quality and purity of genomic DNA were tested by spectrophotometer and electrophoresis
  • A260/280 is between 1.8 and 2.0 (detected in 10 mM Tris-Cl, pH 7.5)
  • RNase treatment to ensure the RNA contamination is eliminated
  • Hind III digestion test: genomic DNA was successfully digested by Hind III
  • ß-actin expression was tested by PCR amplification for Genomic DNA or PCR ready genomic DNA
