查询词典 avidin

The primary conclusions of the present work are as following first, the charges of membrane sarface effect the rate of protein adsorption, but do not effect the amount of protein ultimately adsorbed second, the nonspecific adsorption of avidin can be detached by adding a suitable amount of bivalent alkaline-earth metal ions; third, the binding of avidin to membrane bound model receptor is astricted remarkable by the latelal steric hindrence.

实验结果表明，膜表面电荷对非特异性吸附的速率有很大的影响，而对最终的蛋白吸附量影响不大；非特异性的吸附可以通过二阶阳离子的脱附而去除；受体蛋白质与配体间的特异性结合受到侧向空间位阻效应的制约。

Immunohistochemical localization of inhibin α-subunit in normal mature rats was carried out by using Strept Avidin-Biotin-Peroxidase Complex .The results showed that there was positive immunoreactivity of the McAb to inhibinα-subunit in heart ,kidney , spleen , lymph ,adrenal gland and pancreas cells. It indicated that inhibinα-subunit existed in the above tissues , But no positive sites were seen in hypothalamus, pituitary, lung and liver, that means they have no inhibinα-subunit. Compared with the ovariectomized rats, the hypothalamus and pituitary of the rats injected with inhibin-α fragment（1～32）showed an positive reaction, suggesting that inhibin α-subunit could pass through the blood-brain barrier .

用链霉亲和素-生物素-过氧化物酶(Strept Avidin-Biotin-Peroxidase Complex， SABC)免疫组织化学方法，以抑制素α亚基单克隆抗体对正常雌性性成熟大鼠各组织的抑制素α亚基进行定位观察，结果显示：⑴大鼠心脏、肾、脾、淋巴、肾上腺、胰腺均呈阳性反应，表明存在抑制素α亚基；下丘脑、垂体、肝脏和肺组织呈阴性反应，表明其不存在抑制素α亚基；⑵与去卵巢大鼠相比，外源注射抑制素α（1～32）片段的大鼠其下丘脑和垂体出现阳性反应，说明抑制素α亚基能通过血脑屏障。

Pretreat the tissue sample with unconjugated avidin if the biotin-avidin detection system is used.

假使您使用生物素蛋白侦测系统，请使用未被结合的抗生物素蛋白先处理该组织细胞。

We used the avidin-biotin complex technique and EGFR monoclonal antibody to evaluate the expression of EGFR in 29 cases of cholesteatoma and 34 samples of normal postauricular skin. Of patients with cholesteatoma, 79%(23 cases) had EGFR-positive cells in the basal layer, 66%(19 cases) in the parabasal layer, and 62%(18 cases) in the upper layer of the epithelial tissue.

本研究利用免疫组织化学酵素抗体法（avidin-biotin-peroxidase complex，ABC method）以 EGFR 单株抗体免疫染色，评估29例胆脂瘤与34例耳廓后皮肤两者组织上皮内 EGFR 阳性细胞之分布表现。

We delivered avidin to the biotin/SiNW-FET surface by injecting an avidin sample into a microfluidic channel system.

在流体实验中，通道的质量传递效应对卵白素与生物素的结合行为有很大的影响。

In the early days avidin extracted from the egg, this egg avidin-alkaline-glycoprotein, and the adsorption of polystyrene carrier highly for ELISA in the background can increase.

在早期，亲和素从蛋清中提取，这种卵亲和素为碱性糖蛋白，与聚苯乙烯载体的吸附性很强，用于ELISA中可使本底增高。

The reason for this phenomenon is that the charge of avidin displays negative when pH value of the solution is 11, which inhibits avidin from conjugation with CdTe nanoparticles via electrostatic attraction.

这一现象证明量子点和亲和素之间是通过静电作用结合的。

However, when the pH value of the PBS buffer solution was adjusted to a value (such as 11) higher than the isoelectric point of avidin, the fluorescence spectrum of the CdTe-avidin solution was shown to be the same as that obtained with CdTe nanocrystals only.

实验证明CdTe量子点－亲和素体系的光谱在pH值从7变到9的范围内几乎没有什么变化，而当体系pH值超过亲和素的等电点时，体系的荧光光谱则会变成类似于单独量子点的谱图。

In order to examine the influence of higher ionic strength on the interaction between QDs and avidin, the fluorescence spectra of free CdTe and CdTe-avidin solution are recorded as a function of increasing NaCl concentration.

实验还考察了盐浓度对QDs-亲和素体系的影响情况，结果发现随着盐浓度的增大，QDs-亲和素体系的荧光峰位逐渐蓝移，而单独量子点的荧光峰位基本不变，这说明盐浓度的增加削弱了CdTe量子点与亲和素分子之间的结合作用。

Advantages of specific coupling between biotin and avidin or streptavidin allow firefly luciferase to be immobilized on solid support coated with avidin or streptavidin, so that more flexible and convenient methods of luminescence assay will be available in application.

利用生物素与配体亲和素或链霉亲和素的特异性耦合，可以将荧光素酶固定到亲和素或链霉亲和素包被的磁珠上，从而使荧光检测的应用更加灵活和方便。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
