Protein-Free Blocking Buffer - TBST (Tris-buffered saline, pH 7.5 with 0.05% Tween -20), 500mL

Protein-Free Blocking Buffer does not contain protein; it is a proprietary formation of non-protein agents that eliminates non-specific binding sites in ELISA, blotting, immunohistochemistry and other applications. The absence of protein from the Protein-Free Blocking Buffer eliminates problems associated with traditional protein based blockers, such as cross-reactivity and interference from glycosylated proteins. Protein-Free Blocking Buffer eliminates any concern associated with regulatory compliance issues where use of animal source components are restricted. Furthermore, Protein-Free ™ Blocking Buffer is compatible with antibodies and avidin/biotin based systems and results in high signal to background ratios. For user’s convenience Protein-Free Blocking Buffers are supplied in widely used TBS (Tris-buffered saline at pH 7.5) and PBS buffers (phosphate-buffered saline at pH 7.5) as well as in separate formulations containing Tween®-20 for improving blocking efficiencies. Features Protein free blocking agent Eliminate or minimize cross reactivity with animal source antibodies and antigens High signal to background ratios Four convenient formats, with and without detergent Ready-to-use
