About a year ago, I cut some lambda phage with
HindIII (L/H3), and I've been using this until recently,
when I ran out.  Someone else cut new lambda, but
hers runs differently than the little of mine that
was left.  the pattern is the same, but the
migration rate is different.  She used up the last
of my L/H3, so no further comparisons are possible,
but I am concerned that my size determinations
have been off or that future ones with this new
batch will be.  What gives?
