General description

For standard applications.

Application

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

Quality

Purity: ≤95% protein, ≤5% H2O; electrophoretically homogeneous
Contaminants: <0.5% Na (flame photometric), <0.006% K (flame photometric), <0.0003% Li (flame photometric), <0.02% Ca (o-cresolphthalein), <0.003% Mg (xylidyl blue), <0.003% heavy metals (as Pb), <0.001% Fe (bathophenanthroline), <0.002% Pi, <0.05% glucose (enzymatic), <0.005% glycerol (enzymatic), <0.025% L-lactate (enzymatic)
