The GEArray microarray technology provides gene expression profiling solutions to researchers in many different fields of study. The key benefit of the GEArray is its pathway-focused gene content. However, each pathway is usually available for specific species and in specific technology platforms or formats. All of these platforms have the same reliable, sensitive, and reproducible performance; only the specific reagents and equipment needed to process the microarrays are different. We therefore recommend finding your pathway and species of interest first, and then choosing the technology or format second. Base that decision on the ease-of-handling and throughput that you need as well as the type of equipment accessible to you. Finally, determine the reagents that you need to use the chosen microarrays.

Follow these easy steps to find the right GEArray for your research:

1. Pick Your Pathway
Use the list of links in the gray left-hand sidebar to find an Application related to your research topic or click the "Complete Array List" link. Browse through the alphabetical list on the new web page and find your pathway of interest. Click on the pathway to see an expanded table of products available for that pathway.

2. Pick Your Species
From the table of pathway-related products, look to the second column to see the species that we represent with this pathway. Microarrays can be available for human, mouse, and / or rat.

3. Pick The Available Technology That Best Suits Your Needs.
The next column will indicate the available technology platforms for your pathway in your species of interest. These include the PCR Array, the cDNA microarray and Oligo microarray. The Oligo GEArrays are available in two different formats, the HybPlate and HybTube formats, which are indicated in the product name.

1. If a pathway is available in both the Oligo GEArray and cDNA formats:
   Select the Oligo GEArray format so that you may take advantage of a cost-savings benefit.

2. If the Oligo GEArray is available in both the HybTube and HybPlate formats:

   1. Choose the HybTube format if you have a rotisserie hybridization oven available and your sample number is small.
   2. Choose the HybPlate format if you don't have a rotisserie hybridization oven available or if you have large number of samples.
      1. Choose the two-day static protocol if you only have a standard 60 °C incubator.
      2. Choose the one-day agitation protocol if you require speed and more throughput.
         Remember that the second protocol requires the GEArray Express Thermoshaker.

3. If the Oligo GEArray is only available in the HybTube format:
   Simply choose that format as long as you have a standard hybridization oven.

4. If your pathway for your species is only available in the cDNA GEArray format:
   Simply choose that format; we will continue to support your studies with these microarrays.
