Increase the percentage acrylamide (%T). If you are running standard
Laemili gels of 10 % or less then you should expect your lower molecular
weight stds to run in broadbands. If you are interested in having all the
bands be sharp, you have several options. 1) Run Tris Tricine gels 2) Run
gradient gels.
Hope this helps
