A Gel of a Problem: running miRNA without acrylamide

Dear MetaFilter, I am new to this forum and this is my first post, hi! I am in a bit of a pickle about a work project, and hope that I may be able to get some help by some fellow sciencey people. The science forums are rarely read and badly out of date, or I would have posted at one of those. I have a deadline for a miRNA PCR experiment, and I have already run the cDNA and PCR for the miRNA. All I have to do is run the miRNA on a gel. The problem: We don't have acrylamide! And neither does our neighboring lab. We only have Agarose with which to make gels, which is only for large fragments, not small miRNA fragments of 20-40 bp. The question: As the percentage of agarose in the gel goes higher, the smaller the size of the base pairs are that can be measured. Could I increase this percentage enough to work for miRNA? Out of respect for the community that doesn't like line returns, I have entered the specifics of this post in the Extended Explanation box, because to me, this post reads like a jumble of nonsense without some kind of organization.
