About Polysorbate 20 / Tween 20 blocking buffer

Buffer helps to prevent non-specific antibody binding. The buffer is used for washes between each immunoreactions, to remove unbound immunological, and eventually for incubation solutions of immunoreagents to reduce unspecific background.

Efficient Blocking for Clearer Results

Polysorbate 20 (Tween 20) blocking buffer effectively reduces non-specific protein interactions during western blots and ELISAs. By occupying potential binding sites, it ensures clearer, more precise assay outcomes. Researchers benefit from improved data reliability, enabling better experimental conclusions.

Convenient Packaging and Storage

Available in a 500 mL liquid format, this blocking buffer is easy to handle and dispense. The bottle packaging safeguards the solution's integrity, while the recommended storage temperature of 15C to 30C maintains its efficacy across various laboratory environments.

FAQ's of Polysorbate 20 / Tween 20 blocking buffer:

Q: How does Polysorbate 20 (Tween 20) blocking buffer improve western blot and ELISA results?

A: Polysorbate 20 minimizes non-specific binding by blocking unoccupied sites on assay membranes, resulting in reduced background noise and enhanced signal specificity during western blots and ELISAs.

Q: What is the recommended storage condition for this blocking buffer?

A: This product should be stored between 15C and 30C to maintain its stability and effectiveness throughout its shelf life.

Q: When should Polysorbate 20 blocking buffer be added during the assay process?

A: The blocking buffer is typically applied after the membrane transfer step in western blots or after coating plates in ELISAs, before the addition of antibodies or detection reagents.

Q: Where can this product be sourced in India?

A: Polysorbate 20 blocking buffer is available from several manufacturers, suppliers, and traders across India, ensuring ready accessibility for laboratories nationwide.

Q: What are the benefits of using this liquid blocking buffer compared to solid or powder forms?

A: As a liquid, this blocking buffer offers convenience, minimizes preparation errors, and is ready to use, which saves time and ensures consistency in assays.

Q: How do you use Polysorbate 20 blocking buffer in a typical western blot protocol?

A: Dilute the blocking buffer to the required concentration if needed, and incubate your membrane with it for the recommended time (usually 1 hour at room temperature) before proceeding with antibody incubations.
