Key Applications of Nucleic Acid Purification in BioBanking

A biobank is a collection of biospecimens directly linked to one’s personal health information that are held for medical research purposes.

Blood Banks

  • Collection of blood for research, emergency medicine, etc.
  • Collects, separates, tests, and stores blood until need for use.
  • Stored blood can be separated into red blood cells, platelets, cryoprecipiate, and plasma for uses specific to the component.

Implications of Nucleic Acid Purification in BioBanking

  • Analysis of DNA sequence can be used to create disease treatments based on biomarkers present within the genetic profile.
  • Population Studies
  • Extracting cfDNA can be especially tricky because cfDNA exists in relatively low concentrations within the plasma.
  • This makes extracting enough cfDNA to be useful for downstream applications like PCR and sequencing difficult.
  • Omega Bio-tek’s products can extract high yielding, high-quality nucleic acids that are suitable for biobanking, even if they occur in low concentrations.
