Genomic DNA

BioChain's genomic DNA is ready-to-use high-quality material isolated from a wide variety of well-documented tissue repositories. We offer customized gDNA as reference samples and bulk OEM manufacturing.


  • Genomic DNA isolated from almost any tissues of human, animal, plants and tumor cell lines
  • Human normal and disease
  • Decontamination of polysaccharide and proteoglycan
  • Male and female control genomic DNAs from humans and various animal species
  • Extensive quality control procedures ensure high quality genomic DNA
  • High efficiency in PCR
  • Documentation of tissues’ clinical histories available


  • SNP analysis, Southern Blotting, and PCR
  • Genomic DNA methylation study
  • Copy number variation (CNV) study
  • Comparative genomic hybridization (CGH) study
  • Genomic DNA library construction
  • Profiling study in gene expression

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)
  • Plant genomic DNA concentration is determined by pico green measurement while other genomic DNA concentration is determined by UV260 measurement
  • 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
