Application

  • Bicinchoninic acid disodium salt hydrate has been used to monitor the levels of reducing sugars, thereby helping in the detection of chitinases.
  • It has also been used to determine the amount of cellulose reducing ends (micromoles/g cellulose).
  • It has been used for determining protein concentration.

Biochem/physiol Actions

Bicinchoninic acid is used for the determination of protein concentration. It is responsible for the making of intense purple complex with cuprous ion (Cu+), in presence of alkaline conditions. The amount of Cu+ is in relation with the protein concentration.

The blood contains high concentrations of circulating extracellular vesicles (EVs), and their levels and contents are altered in several disease states, including cardiovascular disease. However, the function of circulating EVs, especially the microRNAs (miRNAs) that they contain, are poorly understood.

Solid tumors contain regions of chronic and cyclic hypoxia. Chronic hypoxia can downregulate RAD51 and sensitize cells to PARP inhibition. Herein, we show that RAD51 expression, cell survival and toxicity to PARP inhibition is not affected under cyclic hypoxic conditions.
