Gel electrophoresis system
A tank with buffer and electrodes, a gel and a DC power supply. Charged molecules such as proteins or DNA move through the gel in the electric field and separate by size, then are stained and imaged.

Gel electrophoresis calibration procedures
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ
Define gel formats, maximum voltage and current, timer, safety interlocks and imaging needs.
- 02
IQ
Check components, leads, power supply labelling and electrical safety, and record serial numbers.
- 03
OQ
Verify power supply voltage, current and timer accuracy with a calibrated meter and load; check interlocks and leak detection.
- 04
PQ
Run a reference protein or DNA ladder and reference standard; confirm resolution and band pattern meet set criteria.
Keep every Gel electrophoresis in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
