Descripción

General description

Phosphate Buffered Saline with 0.05% Tween^® 20 or PBST contains PBS buffer with a low-concentration of Tween^® detergent. It is a common wash buffer and due to the presence of detergent, it can easily remove or block excess components thus reducing foaming and non-specific binding on the membrane and microtiter plate wells.

Application

PBST is used in research in a variety of assays including DNA or RNA hybridization assays and cell culture. It is commonly used for immunoassays like Western blot, ELISA, Dot blot, Immunohistochemistry (IHC), immunopercipitation (IP), and immunofluorecence. It has been used for incubation and wash buffer for peptide microarrays for performing High-density peptide array (HDPA) to analyze antibody responses against SARS-CoV-2.

Features and Benefits

• Ready-to-use buffer
• No measuring and pH adjusting needed
• Save time and minimize effort
• Biological tests: free of DNase, RNase, protease, and nickase
• Chemical tests: Iron ≤10 ppm, lead ≤5 ppm

Packaging
