Johns Hopkins uses hen egg white lysozyme for its intro biochem
lab. Easy to make a whole bunch of it, obvious where it comes
from, and easy to assay in a biologically meaningful (as well
as very cool) way--by looking at the turbidity of a
solution of bacteria that have been fed to the lysozyme, you
can watch them get eaten over time.
All in all a great choice for an intro lab.
Hope this helps.
