Chromium yeast has not only plentiful organic chromium but also abundant protein、nucleic acid、hepatin、fat、biotin、Vitamin B、viosterol and other trace elements.

富铬酵母不仅含铬量高，还含有丰富蛋白质、核酸、糖原、脂肪、生物素、多种B族维生素、固醇和其他多种微量元素，因此具有很高的营养价值。

The detectable group, biotin-ε-aminocaproic acid N-hydroxysuccinimide ester, is attached to the remaining amino group. A series of multiamine compouds, i. e. ethylendiamine, 1, 6-hexandediamine, triethylenetetramine, tetraethylenepentamine, and synthetic polyarylamide are used inlabelling, it is found that linker arms and steric hindrance effect the detection sensitivity. The probes labeled by 1, 6-hexandediamine and triethylenetetramine can detect 0.1-0.5pg target DNA in dot blot hybridization, and their sensitivities are better than the others.

本文详细考察了乙二胺、己二胺、二乙烯三胺、三乙烯四胺、四乙烯五胺及合成的聚乙烯胺化合物对λDNA探针的标记和检测的影响，发现胺化物链长和空间位阻影响探针的杂交和检测，用己二胺和三乙烯四胺标记的生物素探针在杂交24小时、显色8小时后检测灵敏度达0.1-0.5pg，超过其它胺化物标记的探针。

Objective: To explore the applicative value of biotinylated dextran amine to anterograde tracing of the corticospinal tract in rat.

目的：探讨生物素化葡聚糖胺对皮质脊髓束示踪的应用价值。

At 76 days postoperation, biotinylated dextran amine anterograde tracing was applied to observe the motor conduction bundle recovery.

术后76 d，生物素葡聚糖胺顺行神经示踪观察运动传导束恢复情况。

Western blotting analysis showed that most of biotinylated membrane proteins are belong to those of low abundance.

Using CP (Colophony-Paraffin) embedding tissue section technique and immunocytochemical method (Streptavidin-Peroxidase, SP), we have investigated the distribution of GABA and 5-HT immunoreactive neurons in the brain of female and male ants, Camponotus Japonicus. Special attention has been paid to the comparative research on the differences between female and male ants. We also try to give possible interpretations leading to these differences in the behavioral aspects.Here we show that in the brain of female and male C.

本实验采用树脂石蜡组织包埋切片技术(国家发明专利ZL98125709.7)和链霉菌抗生物素蛋白-过氧化物酶(Streptavidin-Peroxidase，SP)免疫组织化学方法，对日本弓背蚁雄蚁和雌蚁成虫脑中的GABA和5-HT能神经元的分布进行了详细的研究，比较了雄蚁和雌蚁的异同，并对可能造成这些差异的行为学联系进行了初步的探讨。

Using Colophony-Paraffin embedding tissue section technique and immunohistochemical streptalidin-peroxidase method, we have investigated the distribution of 5-HT neurons in the brain of Camponotus japonicus, compared the immunoreactivity with GABA, and primarily discussed the character of 5-HT distribution.

Applied rabbit anti-5-HT and mouse monoclonal anti-TPH antisera, the localization of 5-HT and its synthesizing enzyme TPH in the visual system, midbrain, and suboesophageal ganglion of the beetle Harmonia axyridis (Coleoptera: Coccinellidae) was studied by Streptavidin-Peroxidase immunohistochemical method on Colophony-Paraffin embedded serial sections.

运用树脂石蜡组织包埋切片技术，结合免疫组化链霉菌抗生物素蛋白-过氧化物酶双染法，采用兔抗5-HT抗血清和鼠抗TPH单克隆抗体，初步构建了异色瓢虫Harmonia axyridis视觉系统、脑中部及咽下神经节5-HT及其合成酶TPH抗原系统的免疫组织化学反应模式。

Applied rabbit anti-5-HT and mouse monoclonal anti-TPH antisera, the localization of5-HT and its synthesizing enzyme TPH in the visual system, midbrain, and suboesophagealganglion of the beetle Harmonia axyridis (Coleoptera: Coccinellidae) was studied byStreptavidin-Peroxidase immunohistochemical method on Colophony-Paraffin embeddedserial sections. An overall observation reveals that the brain structure of the beetle is relativelydistinct.

To improve detection efficiency and result accuracy, we developed an improved multiplex PCR technique for specific detection of GMO.①The assay strategy involves multiplex PCR amplification of the target with several biotinylated primer pairs in one tube, followed by the hybridization of multiplex PCR products and membrane-bound oligonucleotide probes. The multiplex PCR/probe hybrid is detected colorimetrically using an alkaline phosphatase conjugate and a chromogenic substrate.

在多基因定性检测技术方面，本文在优化并确定了多基因PCR反应条件的基础上，采用了两种方法对多基因PCR产物进行鉴定：①采用共价结合方法将多个探针固定在Biodyne〓C膜上，将5'端标记生物素的多基因PCR产物与膜上的探针进行杂交及显色反应，首次建立了GMO的多基因PCR-膜相杂交检测方法，实现了一个反应体系中同时检测多种转基因成分的目标，提高了检测效率与准确率。
