General description

For standard applications.


Bovine Serum Albumin Fraction V is suitable for standard applications such as:
  • Stabilizer to prevent proteolysis and denaturation of enzymes and other proteins, especially when the proteins are present in low concentrations.
  • Buffer component in immunochemistry, biochemistry, cell biology, or molecular biology
  • Reducing agent
  • Protein blocker for saturation of protein binding sites in ELISAs, Southern blots, and western blots
  • Media supplement for media that require addition of protein
  • Carrier protein
  • Standard protein in gel electrophoresis and protein determination
