Biological Buffers

Research Organics is a primary manufacturer and major supplier of a complete line of high purity biological buffers, such as HEPES, Tris, MES, ADA, PIPES, CAPS, ACES, BES, Bis-Tris, Tricine and Imidazole, and their salt derivatives. Research Organics was the first manufacturer to introduce a high purity HEPES that was colorless in solution, which is now regarded as an industry standard. We also invented a second-generation of "Good's" buffers based on the zwitterionic character of aminoalkylsulfonates originally described by Good: MOPSO, CAPSO, TAPSO, DIPSO, POPSO, HEPPSO, AMPSO and their salt derivatives.

Research Organics also offers high quality buffer solutions such as TBE, TAE, TGS, and SSC blends. These solutions, available as concentrates and at "ready to go" working strength, are packaged in one-liter plastic bottles and a four-liter bag-in-a-box. The four-liter bag-in-box has a pre-attached spigot for convenient dispensing into small containers.

All buffers are tested to ensure conformance to strict chemical specifications and provide lot-to-lot consistency. Buffers designated Molecular Biology Grade are tested for the absence of DNase, RNase and bacterial contamination to assess suitability in molecular biology and tissue culture applications. For customers with special requirements, we will also test for the absence of protease and endotoxin contamination.
