Protein-Free Blocking Buffer (1 Citations)

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 Non-Protein 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.
