The Effects of Centrophenoxineon Parkinson’s disease in CaenorhabditiselegansMethodology
Caenorhabditis elegansham-1(ot339) obtained from the Caenorhabditis Genetics Center (CGC)
Given 6.8 mMcentrophenoxine:
No centrophenoxine is applied:
C. elegans will be cultured in the Nematode Growth Media at 20 °C , and fed Escherichia coli(op50). 6.8 mMcentrophenoxine will be applied to the NGM where the C. elegans are cultured and observed throughout lifespan.
Qualitative data will be collected on how strong both the GFP and lipofuscin fluorescence is-using a scale that ranges the strength of fluorescence.
