Principle of the Array

The Proteome Profiler Human XL Cytokine 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). Captured proteins are detected with biotinylated detection antibodies (Step 2) and then visualized using chemiluminescent detection reagents (Step 3). The signal produced is proportional to the amount of analyte bound.

Why Use an Antibody Array to Detect Multiple Cytokines?

Determining the expression of multiple cytokines 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 cytokines in a single sample can be cost-effective and also save time and sample.

The Human XL Cytokine Array detects multiple cytokines, chemokines, growth factors and other soluble proteins in cell culture supernates. Cells were untreated or treated as indicated below. 500 µL of cell culture supernate was run on each array. Data shown are from a 10 minute exposure to X-ray film. Profiles of mean spot pixel density were created using a transmission-mode scanner and image analysis software.
