PBS Tween 20 Tablets, pH 7.4

Our PBS with Tween 20 pH 7.4 Tablets offer a highly convenient and precise way to prepare Phosphate Buffered Saline with Tween 20 (PBST) solutions. Designed for ease of use, each tablet is formulated to yield 500 mL of 1X PBST solution at a stable pH of 7.4 when dissolved in distilled water. The inclusion of Tween 20 makes this buffer particularly suitable for applications requiring reduced non-specific binding.

Key Features:

• Ready-to-Use Format: Eliminate the need for weighing and pH adjustments. Simply drop a tablet into water for instant PBST.
• Precise pH Control: Each tablet ensures a consistent pH of 7.4, critical for sensitive biological applications, especially antibody-antigen interactions.
• Consistent Concentration: Formulated to provide a 1X PBST solution, minimizing dilution errors and ensuring reproducible results.
• Long Shelf Life: Stable and easy to store, reducing waste and ensuring availability whenever needed.
• Optimized for Immunoassays: The integrated Tween 20 surfactant helps to reduce background noise and improve signal-to-noise ratio in various immunoassay procedures.

Established Applications:

PBST is a widely used buffer solution in biological research, especially where the reduction of non-specific binding is crucial. Some established applications include:

• Western Blotting: Essential for washing membranes to remove unbound antibodies, reducing background and improving signal clarity.
• ELISA (Enzyme-Linked Immunosorbent Assay): Used for washing steps between incubation periods to remove unbound reagents and minimize non-specific binding.
• Immunohistochemistry (IHC) and Immunofluorescence (IF): Employed for washing steps to reduce non-specific antibody binding and enhance specific signal detection.
