Proteome Profiler Human Phospho-Immunoreceptor Array Kit

Kit Summary

A membrane-based antibody array for the parallel determination of the relative phosphorylation of human immunoreceptors. Validated for analyte detection in cell lysates.

Troubleshooting Guide

Principle of the Assay

The Proteome Profiler Human Phospho-Immunoreceptor 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). Tyrosine phosphorylation of the captured proteins is detected with an HRP-conjugated pan phospho-tyrosine antibody (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 immunoreceptors 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.
