Application

Various concentrations of Deoxyribonucleic acid, low molecular weight, from salmon sperm has been used:
  • to study DNA binding to silicon-substituted hydroxyapatite nanocrystals.
  • in simple electrochemical DNA biosensors to detect and evaluate DNA damage caused by UV-C radiation and reactive oxygen species.
  • as a precursor in the synthesis of the bio-dots.

Actions biochimiques/physiologiques

Salmon sperm DNA is often used as a blocking agent invarious research applications. It isknown to improve the specificity and sensitivity of the multi-AP assay byreducing non-specific binding and background signal.

LPS is well recognized for its potent capacity to activate mouse macrophages to produce TNF-alpha, an important inflammatory mediator in bacterial infection-related diseases such as septic shock. We demonstrate here that while inducing only low levels of TNF-alpha alone, DNA
