Electrophoresis Gel?

[Jim Fegan]

	My Biotechnology class has divided up into small teaching 
groups, so we can go to various middle schools and show them how to 
properly execute the electrophoresis (sorry about spelling) 
lab.  
	Our teacher is running on a short budget though, and she is 
reluctant about the use of agarose gel because of it's cost.  Our lab 
group was looking for a possible alternative to the agarose.  Our ideas 
were few, and we even tried geletine, but it ended up melting under the 
current.  
	Does anyone know of a gel that would provide a suitable matrix 
for the electrophoresis?  If you could email me any suggestions you 
might have, I would greatly appreciate it.

Thank you in advance,
Jim
