Extraction and crystallization kit for parietin (Lichens)

Carry out two experimental activities with your students!
 
Xanthoria parietina is a lichen that is abundantly found on walls and trees. It has the particularity of being an association between two symbionts, genetically distant, an alga and a fungus. 
The more the lichen is exposed to the sun, the more orange it becomes. This color is linked to a metabolite, parietin, a substance secreted by the fungus that protects the alga from UVA and UVB rays. 

This kit allows you to first extract parietin and then visualize the protective activity against UV using dosimeter plates (ref. 591066). You can also crystallize parietin to observe under a microscope. 

Format: 30 tests

The kit consists of:
- 1 bottle of acetone (30 ml)
- 1 bottle of crystallization reagents (30 ml)
- 4 Pasteur pipettes
Delivered in two syrup cap bottles, the handling is completely secure.
