The key to outstanding, reproducible electrophoresis results is temperature control. Gels unequally cooled on their two faces produce slanted bands appearing as broad or double bands in stained gels. SE 600 Ruby™ ensures uniform heat in gels because, firstly, the gels are completely immersed in the lower buffer for uniform heat transfer and, secondly, a standard magnetic stirrer circulates buffer around the vertically suspended heat exchanger to maintain homogeneous lower buffer temperature. The ergonomically designed SE 600 Ruby™ provides two built-in side handles, which facilitates carrying and handling.

Storage: Room Temperature, desiccate, store under nitrogen.
Dimethyl Sulfoxide is a dipola, aprotic solvent. It has been shown to accelerate strand renaturation (1-10% concentration) and is believed to give the nucleic acid thermal stability against depurination.
Dimethyl Sulfoxide is used to enhance dermal absorption of many chemicals, as a solvent for many organic and inorganic compounds including fats, carbohydrates, dyes, resins, and polymers, in antifreeze or hydraulic fluids, as a cryopreservative for cell cultures, oxidation of thiols and disulfides to sulfonic acids, as a PCR cosolvent to help improve yields, especially in long PCR. DMSO is routinely used in polymerase chan reaction (PCR), amplification of cDNA libraries, DNA sequencing, column-loading buffers for poly (A)+ RNA selection, buffers for the transformation of competent E. coli, and transfection protocols.
To prepare sterile solutions use a teflon or nylon membrane to sterile-filter the DMSO - do not use a cellulose acetate membrane.
