About Us

Experience the Smoothest Path To Clinic And Beyond

Scorpion Biological Services offers a range of services and analytical test methods to support pre-clinical studies for large molecule product development. Our team has a depth of experience and knowledge in bioanalysis including stability, pharmacokinetics (PK), toxicokinetics (TK), immune profiling and cell-based potency assays. We can conduct a wide range of studies within pre-clinical product development and IND-enabling programs.

Biologics & New Modalities

Scorpion Biological Services (Scorpion) is a contract research, and contract development and manufacturing organization (CDMO) focused on cell- and gene-based therapies and large molecule biologics. We provide a broad array of biologic manufacturing, analytical and R&D services to pharmaceutical and biotech companies to advance their discoveries and deliver new therapies to patients from our San Antonio facilities, with a focus on offering services using American equipment, reagents, and materials.


Our biomanufacturing services focus on accelerating product development timelines from preclinical evaluation to first-in-human studies and beyond in support of commercial manufacturing programs. By integrating analytical methods development, process development, cGMP manufacturing product characterization, and QC release testing, we can efficiently develop a client-specific clinical manufacturing solution that enables a faster path to clinical trials and product commercialization.

Analytical Testing

Our analytical services include development of a comprehensive range of analytical test methods to characterize complex biologics, including cell therapy-based products, protein therapeutics, vaccines, and advanced therapies. Test methods can be qualified or validated for use in measuring product quality and consistency in lot characterization and release, as well as stability testing programs. A variety of analytical methods are available, including compendial and client-specific/custom assays. Our stability programs are conducted under ICH guidelines and are designed to meet both client and regulatory requirements.

Clinical-Scale Facility

Scorpion has completed construction on a new clinical-scale biomanufacturing facility at the VelocityTX Innovation Center in San Antonio, Texas, which is fully operational. The facility offers ~2,000 sq. ft. of process and analytical development space and ~8,000 sq. ft. of cGMP-compliant cleanroom manufacturing space. Biomanufacturing capabilities include upstream and downstream processing up to 1,000L scale for mammalian and cell therapy-based products and up to 200L scale for microbial-based products.

Experience & Capabilities

Scorpion has experienced, client-facing program and project managers who are collaborative, transparent, and strong in communication, so we act as a seamless extension of your operation, able to offer you data insights based on a range of assays, and services to support your products. Our growth will facilitate the integration of bioanalytical services and biomanufacturing.

Made in America

Scorpion is an entirely American company; from our ownership, locations, major equipment such as Pall Allegro bioreactors, consumables and reagents, we strive to create a development chain that is American-sourced.
