Principle of the Assay

The Proteome Profiler Human Phospho-Kinase Array Kit is a membrane-based sandwich immunoassay. Capture antibodies spotted in duplicate on nitrocellulose membranes bind to specific target proteins present in the sample (Step 1). Phosphorylation of captured proteins is detected with biotinylated phospho-specific detection antibodies (Step 2) and then visualized using chemiluminescent detection reagents (Step 3). The signal produced is proportional to the amount phosphorylation in the bound analyte.

Why Use an Antibody Array to Detect Receptor Phosphorylation?

Determining the phosphorylation of multiple kinases 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 phosphorylations in a single sample can be cost-effective and also save time and sample.

Each Human Phospho-Kinase Antibody Array Kit contains most of the necessary components for a ready-to-run assay without the need for specialized equipment.
