Dear friends as i am working on Parkinson's disease by using 6-OHDA and MPTP induced PD in rat model. As i already finished most of study by using 6-OHDA and MPTP but due to insufficient fund i cant procure MPTP for further study. I am expecting a very small quantity (50 mg), if a one can help me it would be very appreciated, also i will acknowledge them in publication also.
