Bovine Serum Albumin (BSA), Fr

Application
Use Bovine Serum Albumin (BSA) as a buffering agent, stabilizer, standard
and for blending. Bovine Serum Albumin (BSA) is also a versatile tool against
non-specific solid phase interference. As blocking reagent Bovine Serum
Albumin (BSA) saturates unoccupied binding sites on the solid phase. Use
Bovine Serum Albumin (BSA) typically at a concentration of 0.5 to 3% within
the reagent buffer.
Benefits
■ Keep your diagnostic reagent free from IgG contaminants.
■ Take advantage of the strongly reduced concentration of heavy metal
ions, sodium and potassium.
■ Rely on the proven diagnostic quality of this product.
