Optimized Blocking Of Porous Nitrocellulose Films For Sensitive Protein Microarrays

Michael A. Shultz, Aki Ohdera, Jason MacManiman, Charles M. McGrath. Grace Bio-Labs, Inc.   ABSTRACT Super G Blocking Buffer was developed to produce low backgrounds in assays using nitrocellulose film-slides.  Using this blocking reagent in combination with ONCYTE® SuperNOVA Film-slides, we achieved an order of magnitude greater sensitivity in a cytokine microarray assay than with … Continued

Inclusion of Super G in All Steps of Protein Arrays Improves S/N

Blocking reagents are used to reduce non-specific protein binding in immunoassays, significantly improving results in terms of Signal-to-Noise ratio. Typically the blocking reagent is added prior to addition of the primary detection antibody.In this study we asked the question as to whether addition of the blocking reagent to other steps in a protein array assay … Continued
