10 Best SomaScan Alternatives & Competitors (2026)

Olink Explore uses proximity extension assay technology for high-plex protein biomarker discovery across thousands of targets. It excels in large population studies with strong reproducibility but typically charges higher per-sample fees than Nomic Bio and provides relative rather than absolute quantification. Turnaround can extend beyond Nomic's one-week service for equivalent cohort sizes.

Luminex bead-based multiplexing supports customizable panels up to several hundred analytes with widespread lab adoption. While flexible, it generally shows lower specificity than nELISA and requires more manual workflow, making it less ideal than Nomic for large-scale absolute quantification projects.

Quanterix Simoa delivers ultra-sensitive single-molecule detection for low-abundance proteins, often used in neurology and immunology. It provides excellent sensitivity but at higher cost per sample and lower plexity than Omni 1000, limiting its use for broad affordable profiling.

Traditional ELISA kits from Thermo Fisher offer validated single or low-plex protein measurements with absolute quantification. They remain cost-effective for small studies yet cannot match Nomic Bio's multiplexing scale, throughput, or panel flexibility for discovery workflows.

MSD electrochemiluminescence assays enable multiplex detection with good dynamic range and sensitivity. The platform supports custom panels but typically involves higher instrumentation costs and slower processing than Nomic's automated service for thousands of samples.

Abcam FirePlex provides bead-based multiplex immunoassays focused on inflammation and oncology markers. It offers solid reproducibility for mid-plex work but lacks the absolute quantification, cost efficiency at scale, and secretome-optimized library found in Nomic Omni 1000.

Bio-Rad Bio-Plex systems run Luminex-style bead assays for cytokine and signaling protein panels. While accessible for many labs, they require more hands-on time and deliver lower throughput than Nomic's fully automated nELISA service with expert analysis included.

RayBiotech Quantibody arrays allow glass-slide based multiplex ELISA with absolute quantification for custom or pre-made panels. The format suits smaller studies but scales poorly compared with Nomic for high-volume projects needing rapid turnaround and consistent lot CVs under 10%.

Proteome Sciences offers mass spectrometry-based proteomics services with broad coverage and biomarker expertise. While strong for unbiased discovery, the approach is slower and more expensive per sample than Nomic Bio's targeted, affordable, absolute-quantified nELISA platform for translational cohorts.
