Because the dimeric form is the active form to exert its biological activities, many trials failed to express TGF β s in prokaryotic systems because of their complex folding manner and disulfide patterns. In 1991 Cerletti and coworkers from Ciba-Geigy Corporation in Switzerland successfully finished the functional expression of human TGF β 2 in bacteria, but the details are protected by the patent.

血管内皮生长因子是一类糖蛋白，除在脑血管的内皮细胞上表达外，在神经细胞上也有表达。

Some isoforms were detected in the serotonin dimeric sprcies The structure of these isoforms need to be elucidated in the future. In conclusion, the dimeric species of serotonin is strongly related to pigment on rice.

目前的研究结果无法确定二聚体的结构，但由结果显示二聚体的含量似乎与水稻外壳的色素变化相关，因此推测 serotonin 二聚体极有可能改变水稻外壳色素。

However, the content of furanocoumarins were found to be very low or even undetectable in Huang-Qin and herbs not belong to Umbelliferae family, their inhibitory effect could be attributed to the dimeric forms of furanocoumarins or other unidentified components (eg. flavonoid).

然而，对於只含有微量或无法侦测到furanocoumarin成分之黄芩和其他非繖形科之中草药，可能还有本实验中未进行分析的dimeric form之furanocoumarin成分或其他flavonoid之成分，造成其抑制代谢酵素CYP3A4的作用。

The SPC-2S fraction with 30% EtOH were constituted epicatechin and epicatechin gallate ester ;The SPC-2S fraction with 50% EtOH contained epicatechin and dimeric procyanidins, another SPC-3S contained epicatechin ,dimeric procyanidins and trimeric procyanidns ;Dimeric procyanidins and trimeric procyanidns constitute SPC-5S fraction;monomer dimer trimer tetramer pentamer of procyanidins were the major fractions in 70% acetone elute solution.

1和 2.01：1，也以添加0.1%SPC酒样中两者的比例最为协调；对小曲酒中酸的影响表现为，添加SPC后有利于降低酒样中乙酸的含量，各酒样中乙酸的量随着SPC添加量高粱外种皮中原花青素及其对小曲白酒挥发性成分影响机制研究的增加而降低；对醛类的影响为，添加SPC可降低酒样中糠醛的含量，其中以添加 0.1%SPC酒样中含量最低，为对照组的39.3%，而4个酒样中乙醛含量则无明显差别；低SPC添加量有降低酒样中杂醇油含量的趋势。

Complexes 7-12, 16, 22 and 23 are dimeric molybdatesor dimeric tungstates, the central metal with citrate or malate in a molar ratio of 1:1. Theanions of these complexes have two metal atoms and two ligands. Each ligand acts as atridentate fashion via theirα-alkoxy,α-carboxy andβ-carboxy groups coordinated to eachmetal atom. Complex 13 is a monomeric molybdate. The citrate ligand coordinates tomolybdenum with itsα-alkoxy,α-carboxy andβ-carboxy groups in a tridentate mode.
