Western Blot (Misshapen / Uneven Bands) moderate

Uneven Dye Front and Band Distortion

Symptom
The dye front shows curving or warping during migration, resulting in uneven band patterns. Bands may appear tilted, curved, or compressed in certain regions of the gel.
Common Causes
  1. 1 Gel overheating during electrophoresis causing uneven field distribution
  2. 2 Field effect due to high ionic strength or conductivity differences
  3. 3 Buffer composition issues affecting ion migration uniformity
  4. 4 Electrical field irregularities from electrode positioning or contact
Solutions
  1. 1 Monitor dye front continuously for uniform migration pattern
  2. 2 Follow manufacturer guidelines for electrophoresis apparatus, gel, and buffer specifications
  3. 3 Ensure proper electrode contact and positioning in buffer chambers
  4. 4 Use fresh running buffer and verify correct buffer composition
