Biocytogen

Antibody discovery and preclinical CRO services

Overview

Biocytogen provides integrated solutions for antibody drug research and development through two main lines: BioMice, a preclinical CRO offering custom gene editing, humanized mouse models, and in vivo pharmacology; and antibody discovery for licensing and partnerships. Its RenMice platforms (RenMab, RenLite, RenNano) generate fully human antibodies using Size-Unlimited and Precise Chromosome Engineering, enabling diverse, high-affinity antibodies. It backs discovery with a large off-the-shelf antibody library via Project Integrum, targeting more than 1,000 antigens and offering licensing and co-development paths. The company stands out by delivering an end-to-end pipeline—from engineered models to antibody platforms and a broad discovery program—designed to shorten clients’ drug development timelines.

Simplify's Take

What believers are saying

  • Revenue reached RMB1.3788 billion in 2025, up 40.6%, with RMB173.2 million profit.
  • Whitehawk announced July 2026 BsADC collaboration, adding upfront cash, milestones, and royalties.
  • NEOK Bio cleared FDA IND in 2026 for NEOK002, validating Biocytogen's RenLite platform.

What critics are saying

  • Whitehawk gets global rights and program control, limiting Biocytogen's downstream economics.
  • If RenMice deal flow slows, CRO margins and licensing collapse into a commodity trap.
  • Harbour litigation reached Shanghai court in June 2026; adverse appeals could disrupt IP confidence.

What makes Biocytogen unique

  • RenMice platforms produce fully human antibodies and humanized models across 1,000+ targets.
  • RenSuper launched May 2026, combining AI selection, validation, and automation for target-to-lead speed.
  • Biocytogen spans discovery, CRO services, and licensing, unlike single-engine platform peers.

Biocytogen and Whitehawk partner to develop ADCs.

Biocytogen and Whitehawk partner to develop ADCs. Recommended companies. Biocytogen and Whitehawk Therapeutics are set to develop bispecific antibody-drug conjugates (BsADCs), as part of a global partnership. Under this collaboration, Biocytogen will offer access to up to five bispecific antibodies via its RenLite platform. Whitehawk Therapeutics will assess them in conjunction with its own ADC linker-payload platform. Following the evaluation, Whitehawk can choose to further advance any resulting BsADC candidates as part of its pipeline. Biocytogen's RenLite platform uses a common light-chain design to support the discovery and optimisation of fully human bispecific antibodies across a wide range of target combinations. This approach is intended to minimise the risk of light-chain mispairing during development and to support subsequent work on BsADCs. The collaboration is structured to leverage Biocytogen's antibody generation capabilities and Whitehawk's expertise in ADC technologies, with the aim of identifying BsADCs that have differentiated targeting characteristics. Biocytogen president and CEO Dr Yuelei Shen said: "Whitehawk has established strong expertise in ADC technology and oncology drug development. This collaboration further expands the application of Biocytogen's fully human bispecific antibodies in ADC development. "We look forward to supporting the efficient advancement of multiple programmes by contributing high-quality antibody molecules and integrated research capabilities to identify differentiated therapeutic candidates and ultimately bringing new treatment options to patients with cancer." Financial terms include an upfront payment to Biocytogen, with eligibility for additional payments tied to development, regulatory and commercial milestones, as well as low single-digit royalties on net sales. Other financial details have not been disclosed. If Whitehawk opts to move forward with any BsADC candidates developed through the partnership, it will hold global rights and complete programme control over them. In April 2026, Biocytogen entered a strategic partnership with Sihuan Pharmaceutical to advance new therapeutics across several disease areas, including weight loss. Related whitepaper.

Technology & Innovation 26/05/2026 22:17 Biocytogen BEIJING-BUSINESS WIRE- Biocytogen today announced the launch of RenSuper Workstation, a next-generation AI-powered antibody discovery platform providing off-the-shelf access to a large-scale, experimentally validated library of fully human therapeutic antibody sequences, together with the RenSuper High-Throughput Antibody Manufacturing Automation Center, a fully automated infrastructure designed to accelerate antibody validation and production. Built on Biocytogen's proprietary RenMice(R) platforms, RenSuper establishes a closed-loop antibody discovery engine combining in vivo immune repertoires, AI-driven candidate selection, automated experimental validation, and scalable manufacturing infrastructure. The platform supports the discovery and development of monoclonal antibodies, bispecifics, multispecifics, antibody-drug conjugates (ADCs), VHHs, and other advanced therapeutic modalities, significantly reducing the time and risk associated with antibody discovery. RenSuper Workstation: AI-Powered One-Click Target-to-Lead Therapeutic Antibody Discovery RenSuper Workstation introduces a new paradigm for one-click therapeutic antibody discovery, transforming antibody discovery from a project-based workflow into a searchable and programmable system. The platform enables rapid identification of high-quality therapeutic candidates with strong developability, functional relevance, and translational potential. Proprietary Fully Human Antibody Library The platform provides off-the-shelf access to fully human antibody sequences against more than 1,000 validated targets, complete with data packages to support more confident decision-making. AI-Powered Candidate Selection RenSuper's AI models are trained on more than 100 million biologically validated antibody sequences, enabling efficient candidate identification against structurally and biologically challenging targets. Using Biocytogen's RenNano(R) fully human HCAb platform as an example, the AI-powered screening workflow achieved an average positive hit rate of 46%, with peak hit rates reaching 98%. The workflow also enriched candidates with superior developability profiles and delivered an 82% success rate for high-purity (>=90%) Fc-format antibody expression. Experimentally Validated Antibody Sequences All AI-selected antibody sequences undergo experimental validation, including binding, affinity, and specificity characterization, ensuring reproducibility, reliability, and downstream development readiness. One-Click Search & Design The platform enables one-click filtering and comparison of antibody candidates by target, epitope, and physicochemical properties. An integrated antibody design platform further supports rapid sequence assembly and flexible format design across multiple therapeutic modalities. RenSuper High-Throughput Automation Center Beyond intelligent discovery, RenSuper integrates industrial-scale automation to establish a scalable, closed-loop antibody development engine. The newly launched automation center enables high-throughput experimental validation of AI-selected antibody candidates with minimal manual intervention, significantly accelerating the transition from molecular design to functional evaluation. The fully automated platform spans the entire protein production workflow, including bacterial inoculation, plasmid extraction, transfection, fed-batch cultivation, and purification. The system consistently delivers antibody yields averaging 50-100 mg, with throughput of up to 800 samples per day and over 5,000 samples per week, transforming antibody validation from a labor-intensive process into a scalable industrial workflow. "We believe the future of antibody discovery will be driven by speed, scale, and data-driven intelligence," said Dr. Yuelei Shen, Founder and CEO of Biocytogen. "With RenSuper, we are building an intelligence-native system that makes antibody discovery more intelligent, scalable, and efficient. Our goal is to reduce the time and complexity of early-stage discovery, accelerate the development of innovative therapeutics, and bring new medicines to patients faster." Together, RenSuper Workstation and the RenSuper High-Throughput Automation Center establish a next-generation target-to-lead ecosystem powered by biologically validated immune repertoires, artificial intelligence, and industrial-scale automation. This milestone further reinforces Biocytogen's vision of becoming the "Global Headstream of New Drugs" by transforming therapeutic antibody discovery into a more intelligent, scalable, and programmable process for biologics innovation worldwide.
