The Ambion® Single Tube Magnetic Stand accommodates one 1.5 mL microfuge tube. With this stand, as with any magnetic stand, centrifugation is replaced by the attraction between capture beads in a solution and the magnet in the stand, resulting in the beads collecting on one side of the microfuge tube. Thus, the captured species (e.g., mRNA) is quickly and efficiently separated from the solution's other components.

Sodium Pyruvate is commonly added to cell culture medium as an energy source in addition to glucose. Since the cells make sodium pyruvate as an intermediate metabolite in the glycolysis pathway, it is not necessary to supplement all cultures. However, if the cells have been grown in medium supplemented with sodium pyruvate, we recommend the supplementation is continued as the cells become accustomed to this addition and their growth will lag without it. Gibco® Sodium Pyruvate, 100 mM Solution is formulated as 11 g per liter of water. The final concentration of sodium pyruvate used in most cell...
