We are headquartered in Beijing, China. Our main facilities are strategically located in Beijing, Haimen, and Boston.
Biocytogen Pharmaceuticals (Beijing) Co., Ltd.
Our headquarters was initially established in Beijing, China in 2009, to engage in the provision of gene editing services, preclinical pharmacology efficacy evaluation services, selling of animal models, antibody development and innovative biologic drug research and development.
Gene Editing Services:
As the foundational technology driving the company’s inception, Biocytogen’s gene editing services, supplies custom, gene-edited animal models and cell lines to domestic and international customers, supports internal product development within the company. Over the past ten years, the company has established a reliable and efficient large-scale technical platform. This platform offers a comprehensive array of animal and cell model services by using several methodologies including traditional mouse embryonic stem cell (ESC)/homologous recombination (HR) technology, CRISPR/Cas9-based Extreme Genome Editing (EGE) technology, and extra-large fragment gene recombination technology (Mb scale) based on chromosome engineering. In 2018, more than 1,500 gene editing projects were delivered to customers around the world. Moreover, Biocytogen’s immune checkpoint, cytokine (receptor) humanized mice, the highly immune-deficient (B-NDG®) mice and RenMab mice are being widely used by multinational pharmaceutical R&D companies.
Biocytogen’s Preclinical Services Division, currently focused in immuno-oncology, oncology, and autoimmunity, has established comprehensive in vivo and in vitro pharmacology capabilities and provided world-class services to a broad spectrum of our customers.
At the core of our in vivo services are a large collection of genetically humanized mouse models of checkpoint inhibitors and cytokine/cytokine receptors, our highly immune-deficient B-NDG mice and their variants, including human immune reconstituted models using human PBMC and CD34+ engraftment, CDX (cell line-derived xenografts) and PDX (patient-derived xenografts) models, and efficient engineering of desired cell line models for both in vivo and in vitro application. Based upon these models, our in vivo pharmacology platform provides in vivo efficacy, pharmacokinetics (PK), pharmacodynamics (PD) and biomarkers, and pathology and toxicology assessments. Complementary to our in vivo capabilities, our in vitro pharmacology platform performs immune cell profiling (e.g. tumor infiltrating lymphocytes (TIL) analysis), cytokine profiling, primary T, NK, and macrophage cell-based functional assays such as T cell activation, mixed-lymphocyte reaction (MLR), T cell cytotoxicity, antibody-dependent cellular cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), target binding, receptor occupancy (RO), cell proliferation and cell death, and cell reporter assays.
We have successfully supported our pharmaceutical and biotech customers in evaluating therapeutics of multiple forms, including biologics (monoclonal antibodies, bispecific antibodies, and recombinant proteins), peptides, small molecules, cell therapy of CAR-T, and oncolytic viruses. In 2018, our Preclinical Services Division has completed over 500 drug evaluation projects for more than 200 partners worldwide. We also successfully assisted our customers in IND applications. Supported by Biocytogen’s large-scale generation of new animal models and advanced gene editing technology, our Preclinical Services Division will continue to deliver high-quality, timely and cost-effective services, provide comprehensive and accurate data, and facilitate the drug discovery and development processes for our customers.
Antibody Discovery Services:
Harnessing our technological strengths, the antibody drug discovery service platform has established a unique set of antibody development technology processes, providing partners with efficient services, and completing the entire process from antibody discovery to IND filing. The advantages of the Biocytogen antibody platform are multifold: First, the high-throughput screening and single-cell sequencing technology is combined with the company’s independently developed fully human antibody mouse RenMab, and the antibody platform can achieve the preparation of therapeutic fully human antibody in one stop. The innovative RenMab technology eliminates the need for humanization of the murine antibody; Second, most biopharmaceuticals, especially antibody drugs, are species-specific, posing a difficulty for preclinical evaluation of efficacy and safety. The antibody platform utilizes novel immune checkpoint humanized mouse models generated in house, thus we can quickly complete the in vivo pharmacodynamics screening and validation of antibodies, maximizing the effectiveness of lead molecules; Last, our state-of-art lab is well suited for full characterization and optimization of antibody molecules, including biological activity, affinity analysis, binding activity, physicochemical properties analysis, antibody engineering, antibody subtype selection, etc. Since its establishment in 2016, the antibody platform has completed hundreds of antibody development projects for its partners. The project cycle can be shortened to 8 months from project approval to completion.

Biocytogen Boston Corporation
Established in the greater Boston area in 2018, Biocytogen Boston Corporation provides antibody discovery services & preclinical pharmacology services to clients in the United States and abroad.
Biocytogen has generated a comprehensive preclinical in vivo efficacy and ex vivo/in vitro pharmacology service platform. In addition to an emphasis on I/O, autoimmune and inflammatory diseases, Biocytogen also offers a variety of CDX and syngeneic mouse tumor models in our Boston site. We perform in vivo efficacy and safety evaluation services on therapeutic candidates (including antibodies and CAR-Ts) for biotech and pharmaceutical companies.
Our experienced and adept in vitro pharmacology team also provides an array of services including immune cell profiling and cytokine analysis. We also provide biochemical/molecular analyses and immune cell functional assays using human and rodent primary cells including MLR, ADCC, and CDC assays.
Moreover, Biocytogen Boston boasts a strong antibody discovery R&D team. Combining our proprietary RenMab (fully human Ig) mouse model with our high-throughput antibody in vivo efficacy screening platform allows us to rapidly develop novel therapeutic antibody candidates. We are actively looking for a partnership to co-develop innovative therapeutic antibodies using the RenMab platform.
