How it works
Simple 4-step Workflow
From sample to data in approximately 3 days, with standard lab equipment.
ELISA-based antibody array assay workflow
1
Extract protein
Lyse cells, tissues, serum, or FFPE using a non-denaturing lysis buffer to preserve protein–antibody interactions.
2
Biotinylate sample
Label the protein sample with biotin using the included reagent. This enables fluorescence detection via streptavidin dye.
3
Incubate array
Apply biotinylated sample to the antibody array slide. Proteins bind to matched antibodies overnight at 4°C.
4
Detect & scan
Add dye-conjugated streptavidin and scan with a compatible microarray scanner. No scanner? Use our free scanning service.

How many slides do I need?
Each pack contains 2 identical slides, one per sample. A minimum of one pack is required to compare two conditions — for example, an untreated control versus a treated sample. For experiments involving multiple conditions or biological replicates, additional packs are recommended.
Do I need additional reagents?
Yes. In addition to the array slides, the Antibody Array Assay Kit is required, which includes a biotin labeling reagent, blocking buffer, and detection antibody. A fluorescent dye-conjugated streptavidin compatible with your microarray scanner is also needed. For more details on additional reagents, refer to page 7 of the User Guide.
What samples are compatible? How much do I need?
The arrays are compatible with a wide range of biological samples including cell lysates, tissue lysates, serum, plasma, conditioned culture media, and FFPE sections. A minimum lysate concentration of 2 µg/µL is recommended, with 80–150 µg of total protein per array slide.
Is this a quantitative or qualitative platform?
The platform is semi-quantitative. Signals represent relative protein abundance and enable fold-change comparisons between samples — for example, treated versus untreated conditions. Absolute protein concentrations are not determined by this method.
What detection system do I need to read the arrays?
A microarray scanner compatible with 76×25×1mm slides is required. Commonly used instruments include the Axon GenePix, Agilent, and Innoscan systems. A list of additional compatible scanners is available here. If a scanner is not available, please consider our free array scanning service.
How do I extract data from the arrays?
Array images are analyzed using microarray analysis software such as GenePix Pro or equivalent tools. GAL files are provided free of charge to facilitate spot identification and signal extraction. Results are typically reported as normalized signal ratios between compared samples.
Do you provide a full assay service?
Yes. Samples may be shipped to our Sunnyvale, CA laboratory for full-service processing, including protein extraction, biotinylation, array hybridization, scanning, and image analysis. Results are delivered by email within 5–15 business days. No specialized equipment or protocol development is required on the customer’s end. Learn more about our full assay service.
Any publications using these arrays?
Our antibody arrays have been cited in over 300 peer-reviewed publications, including journals such as Nature, PNAS, JCI Insight, Cancer Cell, and Cancer Immunology Research. A full list of publications is available on our publications page.
