Proteome Profiler Human NFkB Pathway Array

A membrane-based antibody array for the parallel determination of the relative levels of selected human NFkB Pathway proteins. Validated for analyte detection in cell lysates.

Principle of the Assay

Carefully selected capture antibodies have been spotted in duplicate on nitrocellulose membranes. Cell lysates are diluted and mixed with a cocktail of biotinylated detection antibodies. The sample/antibody mixture is then incubated with the array. Any protein/detection antibody complex present is bound by its cognate immobilized capture antibody on the membrane. Streptavidin-Horseradish Peroxidase and chemiluminescent detection reagents are added, and a signal is produced in proportion to the amount of protein bound. Chemiluminescence is detected in the same manner as a Western blot.

Why Use an Antibody Array to Detect Multiple Proteins?

Determining the expression of multiple Proteins in a single sample can be expensive, time consuming and can require specialized equipment. Performing multiple immunoprecipitations and Western blots requires time, labor, and reagents. The use of a multiplex antibody array to detect multiple proteins in a single sample can be cost-effective and also save time and sample.
