Gene bcl-2 and bax expression in tissue sections were assayed with immunohistochemistry supersensitive kit with a streptavidin-biotinperoxidase complex method.

应用链霉菌抗生物素蛋白-生物素-过氧化物酶复合物法免疫组化染色超敏试剂盒检测血管壁bcl-2、bax基因表达情况。

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。

Avidin-biotin complex ELISA in detecting the specific antibody in patients infected with Clonorchis sinensis was studied.

生物素一亲和素这一生物反应放大系统引入酶联免疫吸附试验建立的ABC一ELISA方法，经对一些可溶性抗原、抗体检测研究，证明敏感性和呈色反应强度均高于常规ELISA，特别有助于低水平抗原抗体检测〔卜7，。

A one-pot chemoselective reduction and lactonization of(4S,5R)-hemiesters was carried out to afford high-yielding(3aS,6aR)-lactone,a key chiral building block for the biotin synthesis. One-step introduction of carboxybutyl chain onto(3aS,6aR)-thiolactone was reached upon treatment of zinc reagent 25 in the presence of nanopalladium via an improved Fukuyama coupling under mild reaction conditions.

在侧链引入过程中，采用纳米钯LDH-Pd~0为催化剂以改进的Fukuyama偶联反应一步高效地引入-生物素五碳羧酸侧链，紧接着创造性地以离子氢化的方式建立了-生物素的第三个手性中心。

However, relatively lower column utilization limits its application to the complex proteome isolation. In case of binding biotin molecules to a specific kind of functional groups existed in protein structure, and flowing the digested peptides over the affinity column in which avidin has been immobilized, biotinylated peptides can be selectively separated and the complicated system is simplified.

因此根据需要，变换生物素试剂与蛋白质反应的作用位点，就可以选择性地分离出不同的目标肽段，从而大大提高亲和色谱柱的使用效率，降低亲和分离的成本；结合乙酰化同位素标记技术，还可以建立多种针对不同目标肽段的特色定量分析方法，ICAT即是将同位素标记与蛋白质巯基生物素化亲和分离成功结合的一个范例。

Contain an enzyme called avidin, which decreases the absorption of biotin. This can lead to skin and hair coat problems.

含有一种叫抗生物素蛋白的酶，阻碍生物素的吸收，导致皮肤和毛发问题。

An abundance of avidin in the duct can result in a deficiency of ''.

导管中抗生物素蛋白过量可导至生物素的缺乏

At the same time, some contain egg protein avidin and biotin in the yolk part of the combination produces a can not be absorbed by the body to use the new material.

同时，一些包含在组合鸡蛋蛋黄部分抗生物素蛋白和生物素蛋白的产生不能被人体吸收利用的新材料。

An abundance of avidin in the duct can result in a deficiency of biotin.

导管中抗生物素蛋白过量可导至生物素的缺乏

In the LAB, the solid phase first, and non-biotin labeled avidin reaction, and then coupled with biotin-labeled enzymes to further enhance the sensitivity.

在LAB中，固相生物素先与不标记的亲和素反应，然后再加酶标记的生物素以进一步提高敏感度。
