一般說明

从雄性和雌性小牛的胸腺分离的高质量双链模板DNA。

特異性

42% GC;Tm = 87 °C.
%GC是指G/C碱基对的百分比。Tm是热变性曲线中点处的温度。

應用

小牛胸腺DNA非常适合用作DNA聚合酶检测的底物、用于扩增非常长的片段以及用作DNA沉淀的载体。它被用作DNA荧光定量的标准品。它被用作参考物质,用于检测软骨组织消化样品的DNA含量。
小牛胸腺DNA非常适合用于作为DNA聚合酶测定的底物、长片段的扩增、以及作为沉淀时的载体DNA。

特點和優勢

•在37°C温育16小时后未检测到核酸酶活性
•高质量的模板DNA

準備報告

阴离子交换色谱纯化,用含1mM氯化钠、1mM EDTA和1mM Trizma HCl的溶液(pH 7.5)透析,并以约2 A260 单位/mL的浓度冻干。约20 260单位/mg DNA。

重構

将DNA溶解在分子生物级水中并轻轻摇动过夜,使终浓度为1mg/ml。

Ternary copper(II) complexes [Cu(NST)2(phen)] (1) and [Cu(NST)2(NH3)2]·H2O (2) [HNST=N-(4,5-dimethylthiazol-2-yl)naphthalene-1-sulfonamide] were prepared and characterized by physico-chemical techniques. Both 1 and 2 were structurally characterized by X-ray crystallography. The crystal structures show the presence of a distorted square planar CuN4 geometry in

Small aromatic compounds like flavonoids can intercalate with DNA molecules bringing about conformational changes leading to reduced replication and transcription. Here, we have examined one dietary flavonoid, quercetin (found in many fruit and vegetables), for possible anti-cancer effects, on HeLa
