Product Description: The product contains the polyhedrin protein co-crystalized with Human MANF. Mesencephalic Astrocyte-derived Neurotrophic Factor (MANF), also known as ARP and ARMET, is secreted and localized at the endoplasmic reticulum (ER) and Golgi apparatus, and expressed in brain, neuronal and certain non-neuronal tissues. MANF selectively protects nigral dopaminergic neurons, versus GABAergic or serotonergic neurons, which suggests that this protein may be indicated for the treatment of neural diseases, such as Parkinson's disease.
