Benchmark A2505 EZ Pack Agarose Tablets, Pack of 1000 Tablets (500g)Researchers trust Benchmark’s Ag (more)arose LE to meet their electrophoreticneeds for a variety of applications. Now the same agarose is availablein a convenient, no mess tablet. The low EEO of the agarose promotes increased electrophoretic mobility,yielding improved resolution and shorter run times. This also allowsmacromolecules and larger particles (subcellular fragments, viruses, etc.)to migrate more freely through the gel matrix. The consistently low EEOreduces band distortion (caused by counter flow) that can result fromthe presence of excessive sulfate-rich negative ions. The quick dissolving EZ Pack tablet contains 0.5g (500mg) ofAgarose LE, eliminating the hands-on time and inaccuraciesnormally associated with weighing. Use of the tablet is not onlyconvenient and cleaner, it also provides better consistency andreproducibility gel to gel. Gel preparation is simple – add the desirednumber of tablets to electrophoresis buffer, allow to sit for twominutes and then heat and pour as usual. The resulting gels arehighly transparent, have exceptional thermal stability (ensuring safeand easy handling) and exhibit exceptionally low absorption ofchemical staining agents. INCLUDED: The Benchmark A2505 EZ Pack Agarose Tablets, Pack of 1000 Tablets (500g) includes: - Benchmark A2505 EZ Pack Agarose Tablets, Pack of 1000 Tablets - Manufacturer's Documentation - 2 Year Manufacturer's Warranty
