Proteome Profiler Rat Cytokine Array Kit, Panel A

A membrane-based antibody array for the parallel determination of the relative levels of selected rat cytokines and chemokines. Validated for analyte detection in cell culture supernates, cell lysates, tissue lysates, serum, and plasma.

Principle of the Assay

The Proteome Profiler Rat Cytokine Array Kit, Panel A is a membrane-based sandwich immunoassay. Samples are mixed with a cocktail of biotinylated detection antibodies (Step 1) and then incubated with the array membrane which is spotted in duplicate with capture antibodies to specific target proteins (Step 2). Captured proteins are 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.

Figure 1. The Rat Cytokine Array detects multiple analytes in cell culture supernates. NR8383 rat alveolar macrophage cells were either untreated or treated as below. Data shown are from a two minute exposure to X-ray film. A, untreated. B, Treated with 100 ng/mL LPS for 24 hours. C, Pre-treated with 100 nM Dexamethasone for 72 hours followed by treatment with 100 ng/mL LPS for 24 hours.

Figure 2. The Rat Cytokine Array detects multiple analytes in tissue lysates and serum. A-B, A rat was injected with 0.1 mg/kg LPS. After 24 hours, tissues were excised and prepared as described in the Sample Collection and Storage section. 400 µg of lysate was run on each array. Data shown are from a 7 minute exposure to X-ray film. C-E, Tissues were excised from untreated rats and prepared as described in the Sample Collection and Storage section. 400 µg of lysate was run on each array. Data shown are from a 7 minute exposure to X-ray film. F, Serum samples from 15 week old male rats were prepared as described in the Sample Collection and Storage section. 100 µL of serum was run on the array. Data shown are from a 5 minute exposure to X-ray film.
