Extra Details:
GeneTex's BSA Blocking Buffers are ready-to-use, 10X PBS or TBS solutions of bovine serum albumin protein for blocking steps in Western blotting, ELISA, immunohistochemistry and nucleic acid detection methods.These blocking buffers are 10% (w/v) solutions of high-quality BSA that are useful for saturating excess protein-binding sites on membranes and microplates in immunoassays. Blocker BSA Buffers are most frequently diluted 10-fold (to 1% BSA) for initial testing, but other buffer concentrations can be beneficial for specific systems. BSA is usually more effective than nonfat milk blocking buffers for biotin-avidin systems because it contains a single purified protein that is devoid endogenous biotin.The purpose of the blocking step in an assay is to improve assay sensitivity by reducing background interference. However, unforeseen cross-reaction of detection reagents with blocking buffers is itself a cause of high background and low signal-to-noise ratios in assay systems. Because individual blocking buffers are not compatible with every system, a variety of blockers in both Tris-buffered saline (TBS) and phosphate-buffered saline (PBS) are available. The best blocking buffer for a specific experiment will bind to all potential sites of nonspecific interaction, eliminating background without altering or obscuring the epitope for antibody binding.To optimize the blocking step for a particular immunoassay, empirical testing is essential. Using inadequate amounts of blocker will result in excessive background. Using an excessive blocker concentration can mask antibody-antigen interactions or inhibit the marker enzyme. For best results when developing a new immunoassay, test several different blocking agents for the highest signal-to-noise ratio in the assay. There is no single blocking agent that is ideal for every occasion because many factors can influence nonspecific binding, including various protein interactions unique to a specific assay system.Features and Benefits: - Purified protein - 10% solutions of high-quality bovine serum albumin; a single purified protein provides fewer chances of cross-reaction with assay components than serum or milk solutions - Convenient - concentrated formulation saves storage space and can be diluted easily to obtain optimal blocking results for specific applications - Easy to use - no waiting for powder to dissolve with this ready-to-dilute liquid concentrate - Flexible - available in PBS and TBS formulations to suit a variety of applications
