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

Optimizing Reverse Phase Protein Array Assays

Components of Reverse-Phase Protein Array (RPPA) methods and their impact on the overall performance of this assay were presented at the 2nd annual RPPA Conference in Edinburgh, Scotland on November 12.  Entire presentation can be viewed here.  View poster here. View here for information regarding our RPPA Assay System Selecting Surfaces, Reagents, and Detection Methods … Continued

SuperNOVA: Superior Porous Nitrocellulose Surface for Fluorescence Detection

Fluorescence detection is a preferred method for many quantitative protein microarray assays in research and diagnostic applications due to its excellent sensitivity and potential for multiplexing.  Use of multiplexed fluorescence-based assays on porous nitrocellulose though has been hampered by high backgrounds at shorter excitation wavelengths (such as the 532 nm fluorescence channel). We have developed … Continued

Super G: Super Blocking and Signal-to-Noise for ONCYTE Film Slides

Fluorescence detection is a preferred method for many quantitative protein microarray assays in research and diagnostic applications due to its excellent sensitivity and potential for multiplexing. Use of multiplexed fluorescence-based assays on porous nitrocellulose though has been hampered by high backgrounds at shorter excitation wavelengths (such as the 532 nm fluorescence channel).  To maximize the … Continued
