Specially formulated to produce greater resolution and more information -- up to 500 DNA bands on a single-load gel. SequaGel XR's optimized, proprietary formulation prevents aberrant band inversions and yields sharp, clear, highly resolved bands. SequaGel XR runs substantially faster than traditional gels, while actually improving resolution. These results are achieved in a comfortable time-tested format, providing full interlaboratory reproducibility. By preventing band inversions, SequaGel XR bands are sharp and true. SequaGel XR provides more information by allowing greater separation between bands near the top of the gel. This effect, similar to a wedge gel, is achieved with standard spacers. The quality and consistency of SequaGel XR is evidenced by the uniform background obtained upon drying. Band edges are sharp. Even without fixing, the gel will dry without cracking or crazing. The result is a finely-rendered, highly detailed DNA gel. SequaGel Complete Buffer Solution contains TBE and TEMED. No dilutions are necessary in this easy to use system. The researcher simply combines the two solutions, adds ammonium persulfate, and casts the gel.
