The Broadest Coverage of the Human Proteome
HuProt consists of over 21,000+ unique human proteins, isoform variants and protein fragments – covering 16,794 unique genes, it is the most comprehensive collection of human proteins available.
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.
Reproducible Protein Distribution
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™ arrays 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).
