Electrophoresis conditions: 1% agarose, TAE buffer, constant voltage at 7 V/cm electric field strength, and 10 ul were loaded. The amplicon comes from a touch down PCR.
The lanes on the right of the gel are overloaded with DNA hence the "fire balling". Even the lanes on the left are somewhat overloaded. So it is neither a reaction or electrophoresis issue. It is a loading issue. Either load less of your reaction or use wells that are larger.
