HuProt™ Human Proteome / Protein Microarray
Unparalleled Insights for Autoantibody Profiling, Biomarker Discovery and Target Identification
With over 21,000+ GST-purified proteins, there has never been a protein microarray as comprehensive or thoroughly validated as HuProt™.
REQUEST INFOThe Broadest Coverage of the Human Proteome
HuProt protein microarray consists of over 21,000+ unique human proteins and isoform variants – covering 16,794 unique genes, it is the most comprehensive collection of human proteins available.
HuProt™ is an advanced platform designed for high-throughput analysis of human proteins. This innovative technology enables researchers to conduct comprehensive proteomic studies, facilitating the identification and characterization of protein interactions. The microarray is particularly valuable for biomarker discovery and the understanding of various diseases, offering an efficient means to analyze multiple human proteins simultaneously. By providing high-resolution and sensitivity, HuProt enhances scientific research capabilities, enabling the generation of impactful insights in autoantibody profiling, biomarker discovery, target identification, therapeutic development, and personalized medicine.
Our industry-leading HuProt microarray includes 15,889 of the 19,613 canonical human proteins described in Human Protein Atlas, with broad coverage across protein subclasses.
Add your own custom proteins to HuProt - on the rare occasion when HuProt does not contain a protein that is of interest to you, we can add that protein(s) for a small additional fee.
Content includes major functional classes such as intracellular proteins, membrane proteins, enzymes, secreted proteins, transcription factors, transporters, GPCRs, cytokines, immune receptors, immune checkpoints, CD markers, ion channels, cytosolic proteins, nuclear receptors. Additionally there is thorough coverage for proteins enriched in major tissues of interest such as testis, cerebral cortex, thyroid gland, skin, fallopian tube, liver, parathyroid, intestine, kidney, spleen, muscle, epididymis, lymph node, bone marrow, adrenal gland, esophagus, heart, appendix, tonsil, prostate, rectum, adipose tissue, stomach, colon, cervix, uterus, gallbladder, seminal vesicle, breast, ovary, endometrium, smooth muscle, salivary gland, pancreas, and bladder.
The HuProt Advantage
HuProt offers the broadest, most accurate coverage of the human proteome
The HuProt™ protein microarray sets a new standard in proteomic research, offering unparalleled breadth and depth with its comprehensive coverage of the human proteome. Featuring an extensive range of folded, 3D proteins, isoform variants and protein fragments, it is uniquely suited for applications such as autoantibody profiling, biomarker discovery, serum profiling, and target identification. HuProt empowers researchers to explore protein interactions—including both protein-protein and protein-small molecule dynamics—providing crucial insights into complex biological mechanisms and unveiling potential therapeutic targets. Engineered for precision, the microarray delivers low background noise and an exceptional signal-to-noise ratio, ensuring reliable high-throughput screening and robust data analysis. By enabling the analysis of thousands of proteins in a single experiment, HuProt streamlines discovery, accelerates research, and transforms the journey from hypothesis to breakthrough. As an indispensable tool for human proteome studies, HuProt drives innovation and delivers impactful results for laboratories worldwide.

Technical Benefits
HuProt utilizes advanced non-contact piezoelectric printing technology, which ensures superior spot morphology and reproducibility compared to traditional contact pin printing methods. Each protein undergoes rigorous purification to select for correctly-folded GST-fusion proteins that maintain their native three-dimensional conformation and biological function. It is designed to deliver remarkably low background noise with exceptional signal-to-noise ratios, enabling reliable high-throughput screening of over 21,000 proteins in a single experiment. This technical precision, combined with the platform's ability to detect both linear and conformational epitopes, provides researchers with robust, reproducible data that accelerates discovery timelines while maintaining the highest standards of analytical accuracy and reliability.
Versatile Applications
Uniquely suited for autoantibody profiling, biomarker discovery, serum profiling, and target identification, enabling researchers to explore protein interactions including both protein-protein and protein-small molecule dynamics
Protein Integrity
Uses properly folded, 3D proteins that retain their native conformation and biological function. This is crucial because many protein interactions depend on proper protein folding
High Reproducibility
Non-contact piezoelectric printing process ensures consistent results with excellent spot morphology and reproducibility across different production batches
High Throughput
Simultaneous analysis of thousands of human proteins in a single experiment, enabling researchers to efficiently screen and profile protein interactions, expressions, and potential biomarkers across various samples
Low Background Noise
Engineered for precision with exceptional signal-to-noise ratios, ensuring reliable high-throughput screening and robust data analysis
Unmatched Accuracy and Reproducibility
CDI Labs’ non-contact piezoelectric ‘inkjet’ process uses next-generation Arrayjet printers and allows for rapid production of high-quality microarray slides time after time. In comparison to older contact pin printing methods, HuProt™ microarrays are made with improved accuracy and reproducibility with excellent spot morphology.
Reproducible Serum and Plasma Profiling
Reproducible Proteome-Wide IgG Autoantibody Immunoprofiling of Healthy Human Pooled Plasma Within and Across HuProt Proteome Microarray Batches
Pooled human plasma was incubated on pairs of HuProt proteome microarrays across two print batches and stained with a fluorescent anti-IgG secondary antibody. Raw median fluorescence intensity data were captured, log2 transformed, and plotted. Linear regression analysis demonstrates reproducibility across the array pair from Lot 1 (R2 = 0.96), Lot 2 ( R2 = 0.92), and the averaged data from both array batches (R2 = 0.96). These results demonstrate the robust reproducibility of HuProt autoantibody seromics data both within and across microarray production lots.
Correctly-folded, Full-length Proteins in Their Native Conformation
Protein purification prior to microarray manufacturing selects for proteins with correctly-folded GST-fusion proteins. Testing on the HuProt Microarray demonstrates that the proteins are folded in native conformation and retain function (Hu S. poster; Venkataraman A., et al., 2018). When both native and denatured HuProt microarrays were probed with monoclonal antibodies that selectively recognize either linear or folded epitopes of their cognate antigen, the antibodies were found to recognize the appropriate antigen form (Venkataraman A., et al., 2018). Further tests (RNA binding) demonstrated that proteins on HuProt do retain function (Venkataraman A., et al., 2018).
