G-Biosciences' FirstChoice™ Blocking Buffer is ideal as a first choice for optimization of new assays and systems, or when determining the optimal blocking buffer for elimination of non-specific binding sites in ELISA, blotting, immunohistochemistry and other applications.
G-Biosciences' FirstChoice™ Blocking Buffer is a proprietary protein formulation that offers greater versatility and lack of cross-reactivity.
G-Biosciences' FirstChoice™ Blocking Buffers are compatible with antibodies and avidin/biotin based systems. The results show high signal to background ratios. This ready-to-use blocking agent is animal serum free and biotin free.
G-Biosciences' FirstChoice™ Blocking Buffers are conveniently supplied in widely used TBS (Tris-buffered saline at pH 7.5) and PBS (phosphate-buffered saline at pH 7.5) buffers as well as in separate formulations containing Tween® 20 for improving blocking efficiencies.
