Protein Express Laboratories

Protein Express Laboratories is a closely held Cincinnati-based biotechnology company focused on antimicrobial and disinfectant products rather than therapeutic drug development. The company has described itself as a bioscience or biotechnology business and has promoted a patented class of nontoxic sanitizers and disinfectants for household, institutional, and commercial use. Public regulatory records show EPA registrations for products including PELS 421 and PELS 422, with registrant listings under Skirdle, LLC and later The Gilla Company, LLC, both doing business as Protein Express Laboratories. The business also appears to have legacy capabilities in recombinant protein and related laboratory outsourcing services, but the most clearly documented commercial activity is antimicrobial surface product development and registration. Overall, this is a small private life-science-adjacent company centered on non-therapeutic antimicrobial formulations and related commercialization.
