Dry your agarose gels and save money. Gel support films are a convenient, low-cost way to document and preserve agarose gels. No more Polaroid pictures. Simply lay a wet stained agarose gel on a piece of film and let the moisture evaporate overnight. The result is a durable dried gel — a permanent record that can be taped directly into a laboratory notebook, reproduced with a copy machine, or photographed. What a great idea.
