The protein sequencing lab here routinely sequences from electroblotted
You can look up: Fernandez, J., et al. (1992) Analytical Biochemistry, 201,
There is also a more recent reference but it was buried under a desk avalanche
a few days ago, and I cannot find it right now (also by Joe Fernandez, et al.).
