BSA Blocking Buffer in PBS is widely used in immunoassays, such as ELISA and Western blotting, to prevent non-specific binding of antibodies to the surface of the assay plate or membrane. By coating the surface with BSA, it blocks unoccupied binding sites, reducing background noise and improving the accuracy of the results. It is also used in immunohistochemistry to minimize non-specific interactions during tissue staining. Additionally, it serves as a stabilizing agent for proteins and antibodies in various biochemical experiments, ensuring their integrity during storage or analysis. Its compatibility with PBS makes it suitable for a wide range of biological applications.
