Effect of Tannic Acid on Nutrition and Activities of Detoxification Enzymes and Acetylcholinesterase of the Fall Webworm (Lepidoptera: Arctiidae).

Yufei Yuan et al.

Journal of insect science (Online), 20(1) (2020-02-16)

Plant tannins, polyphenolic plant secondary metabolites are involved in important chemical defense processes in plants. In this study, tannic acid was used as the standard of plant tannins to determine the effects on nutritional indices and activities of glutathione S-transferases…

Post-harvest UV-B irradiation induces changes of phenol contents and corresponding biosynthetic gene expression in peaches and nectarines.

Claudia Scattino et al.

Food chemistry, 163, 51-60 (2014-06-11)

In the present study the possibility of enhancing phenolic compound contents in peaches and nectarines by post-harvest irradiation with UV-B was assessed. Fruits of ‘Suncrest’ and ‘Babygold 7’ peach and ‘Big Top’ nectarine cultivars were irradiated with UV-B for 12…

Isoprene emission by poplar is not important for the feeding behaviour of poplar leaf beetles.

Anna Müller et al.

BMC plant biology, 15, 165-165 (2015-07-01)

Chrysomela populi (poplar leaf beetle) is a common herbivore in poplar plantations whose infestation causes major economic losses. Because plant volatiles act as infochemicals, we tested whether isoprene, the main volatile organic compound (VOC) produced by poplars (Populus x canescens)…

說明

一般描述

胸腺嘧啶是脫氧核糖核酸（DNA）中發(fā)現(xiàn)的四個(gè)核堿基之一，其他三種包括腺嘌呤、鳥嘌呤和胞嘧啶。

應(yīng)用

胸腺嘧啶已作為標(biāo)準(zhǔn)含氮堿基，用于高效液相色譜-紫外線（HPLC-UV）（用于定量骨DNA樣品）和 拉曼散射實(shí)驗(yàn)中。它也已被用作C2C12成肌細(xì)胞的補(bǔ)充劑。胸腺嘧啶可用于研究影響DNA結(jié)構(gòu)的化學(xué)過程，例如輻射誘導(dǎo)的自由基產(chǎn)生，從而導(dǎo)致堿基發(fā)生交聯(lián)反應(yīng)和衍生化。它可用于研究與其他核堿基（如腺嘌呤）的氫鍵動(dòng)力學(xué)和能量參數(shù)。胸腺嘧啶可用于基于配位化學(xué)和納米粒子結(jié)構(gòu)開發(fā)靈敏的重金屬（汞）檢測器。

包裝

5, 10, 25, 100 g in poly bottle

生化/生理作用

用于研究DNA結(jié)構(gòu)的胸腺嘧啶通過輻照方法以進(jìn)行交聯(lián)反應(yīng)和衍生化。胸腺嘧啶二聚體可用來表示DNA損傷。胸腺嘧啶與金屬（汞）一起使用可形成胸腺嘧啶-HgII-胸腺嘧啶（T-HgII-T）雙鏈體。在細(xì)菌中進(jìn)行胸腺嘧啶饑餓會(huì)導(dǎo)致DNA合成停止，這被稱為無胸腺嘧啶死亡。
