Green Mountain Antibodies

Green Mountain Antibodies is a long-established, privately-held contract service provider focused on custom antibody generation and production. The company leverages a broad technical expertise in immunology, protein science, and molecular biology to deliver tailored monoclonal, polyclonal, and recombinant antibodies for research, diagnostic, and therapeutic development. With a proven track record spanning over two decades, GMAb emphasizes a collaborative, customer-centric approach, operating from its accredited facility in Vermont. Its business model is entirely service-based, generating revenue through client-funded projects and the sale of a limited catalog of off-the-shelf antibody products.

Integrated suite of antibody development technologies including hybridoma generation, recombinant antibody expression (e.g., mammalian systems), polyclonal production via RIMMS protocol, anti-idiotypic antibody development, and comprehensive characterization services (affinity, specificity, isotyping).

GMAb competes in the fragmented antibody services market against large, full-service CROs (e.g., GenScript, Abcam), specialized antibody boutiques, and academic core facilities. Its differentiation is based on deep technical expertise, a collaborative service model, niche specialization (e.g., hemostasis), and its reputation for quality built over decades, rather than competing on scale or lowest cost.
