Description

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
