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 nonspecific
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% in the reagent
buffer.
Benefits
■ Keep your diagnostic reagent free from IgG contaminants.
■ Take advantage of the strongly reduced concentration of sodium, and
potassium.
