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


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)

Southwestern blotting is used to investigate DNA-protein interactions. The advantage of this technique over other related methods such as electrophoretic mobility shift assay (EMSA) and DNA footprinting is that it provides information regarding the molecular weight of unknown protein factor....

Test and evaluation of engineered biothreat agent detection systems ("biodetectors") are a challenging task for government agencies and industries involved in biosecurity and biodefense programs. In addition to user friendly features, biodetectors need to perform both highly sensitive and specific...
