ElectroSNAP acrylamide buffer blend is mainly used in the preparation of polyacrylamide gels of small size DNA and RNA (>20 bp), which can then be used in routine analysis of PCR products, for monitoring nuclease and ligase reactions, and for the chemical modification of oligos, analysis and small scale purification of nucleotide from mixtures of oligonucleotides. It can also be used to monitor the purity and breakdown of DNA labeled and unlabelled primers, probes, etc. The formulation of acrylamide and buffer blend resolves small DNA and RNA fragments and oligonucleotides and is useful for analysis of gene mutation and ascertaining siRNA purity and stability. It is stable at room temperature for at least 6 months and will resolve fragments smaller than 30 bp. AMRESCO Inc. 800-366-1313 www.amresco-inc.com

DNA MicroMarker was separated on an 8% and 12% ElectroSNAPgel (Lanes 1-3). 30-mer (DNA) was run in Lanes 5-7 and 21-mer (DNA) was separated in Lanes 8-10. The gels were subsequently stained with ethidium bromide.
