Cleaning Gel Plates

A gel is poured between two glass plates. Any dust particles or other contaminants on the plates can interfere with the collection of fluorescence data by scattering the laser excitation or the fluorescence emission light. Cleaning glass plates is time consuming but essential to obtaining good fluorescent signal with low background. Special low fluorescence plates cost around $150 per pair compared to standard glass plates that are about $50 per pair.

When plates are cleaned, the gel has to be removed since it is bonded to one or both plates. The plates are often soaked to simplify the gel release. Cleaning usually takes about 5-10 minutes for a pair of plates once the gel has been removed.
