Partnerships

Two partnerships are on record, tiered core and minor.

• Biocare MedicalcoreStrategic or Co-development Partner · 23 March 2026Strategic collaboration and co-development agreement to advance next-generation antibody solutions for modern pathology workflows. Combines Proteintech's antibody discovery and protein engineering capabilities with Biocare's diagnostic assay and immunohistochemistry expertise. Aims to accelerate development of high-performance antibody reagents for tissue-based diagnostics, translational research, and precision oncology applications including antibody-drug conjugates and companion diagnostics. Addresses industry-wide challenges related to antibody reproducibility and assay standardization as digital pathology adoption grows.
• 10x Genomics (Acquirer of Proteintech Genomics Division)minorOthers10x Genomics acquired Proteintech Genomics, a division of Proteintech Group that developed high-plex proteomic solutions for single-cell and spatial biology applications. The deal included the Human Discovery Panel, the largest antibody-based single-cell protein panel compatible with 10x Genomics' Flex chemistry workflows. Transaction terms were not disclosed. Proteintech retains its core antibodies, proteins, and immunoassays business.

Direct peers

• Cell Signaling Technology: Privately held manufacturer of research antibodies and reagents with strong brand among academic and pharma researchers; directly comparable to Proteintech in catalog breadth, application focus (WB, IHC, IF, FC), and recombinant antibody strategy.
• Abcam (Danaher): Global research antibody supplier acquired by Danaher in 2023; competes head-to-head with Proteintech in primary and secondary antibodies, recombinant antibodies, and immunoassays across academic and industrial customers.
• Bio-Techne (R&D Systems / Novus Biologicals): Public life science tools company housing R&D Systems (proteins, cytokines, ELISA kits) and Novus Biologicals (antibodies); directly overlaps with Proteintech's HumanKine, ELISA, and antibody product lines, with additional GMP reagent capabilities.
• Santa Cruz Biotechnology: Long-standing research antibody supplier covering a broad catalog of polyclonal, monoclonal, and conjugated antibodies for WB, IHC, IF, and ChIP; competes directly with Proteintech in academic research segments.
• Atlas Antibodies: Sweden-based antibody company spun out of the Human Protein Atlas, focused on highly validated antibodies for IHC, WB, and IF; competes with Proteintech on recombinant antibody quality and proteome coverage.
• Jackson ImmunoResearch: Specialty manufacturer of secondary antibodies and immunoreagents; directly comparable to Proteintech's secondary antibody portfolio and conjugated reagent offerings.

Broad incumbents

• Thermo Fisher Scientific (Life Sciences / Antibodies): Diversified life science tools giant offering antibodies, proteins, and immunoassays as part of a broader portfolio that includes instruments, reagents, and services; competes with Proteintech across most product categories but as one of many priorities.
• Bio-Rad Laboratories: Established life science research and clinical diagnostics company with antibody, protein, and immunoassay offerings; comparable to Proteintech in research reagent categories but operates a broader portfolio across instruments and clinical diagnostics.
