And Storage

The DNA tetrahedron (Td), as one of the novel DNA-based nanoscale biomaterials, has been extensively studied because of its excellent biocompatibility and increased possibilities for decorating precisely. Although the use of Td in laboratories is well established, knowledge surrounding the factors influencing its preparation and storage is lacking. In this research, we investigated the role of the magnesium ions, which greatly affect the structure and stability of DNA. We assembled 1, 2, 5, 10 and 20 μM Td in buffers containing different Mg2+ concentrations, demonstrating that 2 and 5 mM Mg2+ is optimal in these conditions, and that yields decrease dramatically once the DNA concentration reaches 20 μM or the Mg2+ concentration is lower than 0.5 mM. We also verified that the Td structure is retained better through freeze-thawing than lyophilization. Furthermore, a lower initial Mg2+ (≤2 mM) benefited the maintenance of Td structure in the process of lyophilization. Hence, our research sheds light on the influence of Mg2+ in the process of preparing and storing Td, and also provides some enlightenment on improving yields of other DNA nanostructures.

AbstractThe dicarbene complexes, MnBr(CO)3 [xxx] (1) and [xxx] (2), are synthesized from metal carbonyl precursors and CNCH2CH2OH . Factors influencing this 2-hydroxyalkyl isocyanide → N ,O-carbene isomerization are discussed. The crystal and molecular structure of 2 shows a distorted trigonal geometry about the central Ni atom. Extensive hydrogen bonding ((N )H ··· F 2.09, 2.38 Å ) occurs between cations and anions giving rise to infinite chains. Other pertinent bonding parameters are Ni-C (carbene) 1.860(4), 1.864(4) Å; C(carbene) [xxx] N 1.309(6), 1.304(6) Å , and C - Ni - C 97.7(2)°.
