About Us

Maine Biotechnology Services brings 30 years of knowledge, experience, process development, and project management to our customers to ensure the best possible antibodies for any application. As antibody development goals in the biotechnology and pharmaceutical industry have evolved, MBS has risen to the challenge to effectively meet those needs.

The cornerstone of antibody and assay development at MBS is our technical team approach to project design and planning. The MBS antibody development plan focuses on the timely generation of data from large fusion screens that allow for the identification of quality antibody candidates.  A rigorous set of innovative and thorough screening tools are creatively developed and executed to meet dynamic customer goals with data-driven decision making. If the goals of a project change during the course of development, MBS will use accumulated data to efficiently shift focus to meet the new goals. Our mission is to use these strategies to go beyond limited contract services and be a comprehensive partner in antibody and assay method development.  MBS saves customers money and compresses timelines of the most complex projects.
