Curved bands

September 21, 2020

Symptom: Bands occur curved within their lanes.
Cause: When samples hold too much salt and/or buffer-ions they change the gel's conductivity in that lane. The isoelectric lines together with the proteins will be no more parallel.
1.   Try another sample application points.
2.   Desalt sample using small columns like NAP-5 (GE 17-0853-01)

No curved bands at neutral sample application point

Curved bands at acidic sample
