Robust, well-validated pre-clinical models of PD are valuable tools for understanding the biology and possible treatment of this complex disease. As a CRO specializing in PD preclinical research, Creative Biolabs offers a commonly used 6-hydroxydopamine (6-OHDA) unilateral lesion rat model to our clients for the assessment of both protective and restorative treatments.
