Profile: Helix Biostructures specializes in therapeutic discovery, physical characterization, protein synthesis, and related software development. Determining the activity and function of a protein target, it must be analyzed through biophysical and structural characterization in parallel with activity assays. Attaining a sufficient amount of purified protein is a prerequisite to completing this analysis. Our custom protein synthesis services (bacteria, insect, and mammalian expression systems) produce crystallization grade recombinant protein having more than 95% purity suitable for any analytical technique.
