Dear Thomas:

The percentage of DNA content in each band is equal to the percentage of
the fragment length of total lambda length (48 502 bp , if I am not
mistaken). You can easily calculate it yourself. Make sure to heat 
lambda/HindIII marker before running your gel: the fragments  4361 and
21360 bp tend to stick together through 11 base cos ends that leads to
underrepresentation of 4361 band. 5 min at 65oC is usually enough.
