1580g
Glucose
3160g
Preservative
142g
Doxycycline (antibiotics)
2.1g
Amoxicillin (antibiotics)

Research
Alzheimer’s disease, or AD
We have transgenic flies which express human Aβ42 or its mutant forms, which can be directly driven in fly neurons using UAS-GAL4 gene switch. These flies have defects in olfactory learning, memory and lifespan. Amyloid deposits and neurodegeneration appear when they get old, as revealed by immunostaining and [...]

Lab apparatus
Brain section
Cross section of fly head (left), and the machine for slicing and embedding the sample (right). Brain section helps to reveal neurodegeneration in neurological diseases and protein spatial expression through immunohistochemistry.
Genetic tools and fluorescent microscopy
With the UAS-GAL4 system and other gene switches, we can easily control, monitor and track [...]
