 [Featured Product]Glyco-enhancer of Plant Fertilization: AMOR

 

 

In plants, "pollen tube attractants" are essential for the pollen tube to reach the ovule. It has been hypothesized that the pistil secretes various activators to render the pollen tube fertile. Prof. Higashiyama and Dr. Mizukami at ITbM (Institute of Transformative Bio-Molecules, Nagoya University) and their colleagues have recently discovered a sugar chain "AMOR" named as an attractant. AMOR features the sugar chain arabinogalactan which is uniquely found in plant cell walls, and is important in the plant cell-to-cell communication.

 [Brochure] Biotinylation Reagents and Avidins

 

Biotin is a natural vitamin which binds tightly to the protein avidin. Since biotin-avidin binding is well-known as one of the strongest protein-ligand interactions, biotin and avidin are used in various biochemical applications. TCI offers many biotin-insertion reagents and some labeled streptavidins.

2-PySO2CF2H : Bench-stable Difluoromethylating Agent for Catalytic Difluoromethylation

Difluoromethyl 2-pyridyl sulfone (1), which is composed of pyridyl and difluoromethylsulfonyl groups, performs as a difluoromethylating reagent when used with metal catalysts. For example, Hu et al. have reported that 1 reacts with aryl zinc reagents (2) in the presence of tris(2,4-pentanedionato)iron(III) and tetramethylenediamine (TMEDA) giving the corresponding difluoromethylated aryl products in good yields. This reaction can be applied to various aryl group substituted zinc compounds such as a phenyl group and others like methoxy-, trifluoromethyl-, or heteroaryl-substituted aryl groups. In this way, 1 is expected to be used directly as a difluoromethylating reagent introducing a difluoromethyl group into aryl groups.

YD2: A Green Porphyrin Dye for Dye-sensitized Solar Cells

 YD2 is a green zinc-centered porphyrin dye used as a sensitizer for dye-sensitized solar cells (DSSCs).1) Although ruthenium-based dyes such as N719 dye and N749 black dye are well known as efficient sensitizers, ruthenium-free sensitizers including porphyrin dyes have also been developed as they do not need to contain any noble metals, which can reduce material cost. YD2 is a promising materials whose power conversion efficiencies attain up to 11% in a device including reflecting particles, and 8.8% in a device without the reflecting layer.2) The material shows a wide bathochromic-shifted Soret band and Q band due to its electron-donating diphenylamino moiety, and an electron-withdrawing carboxyphenylethynyl at the meso-positions of the porphyrin ring.
