半乳糖苷

Soya bean cake is appled as the widest vegetal protein feedstuff at present time, but it includes a kind of anti-trophic factor of alpha-galactosis oligosaccharide such as raffinose、 stachyose、 verbascose etc, which affects absorbation and utilization of nutriments.

豆粕是目前应用最广泛的植物性蛋白饲料，但豆粕中含有一类α-半乳糖苷低聚糖抗营养因子，影响营养物质的吸收利用，如棉子糖，水苏糖等。

In plant,the enzymes of RFO,such as galactinol synthase,myo inositol-1-phosphate synthase, raffinose synthase and stachyose synthase,are linked with the RFO pathw.

寡糖代谢是一个复杂的调控体系，其中肌醇-1-磷酸合成酶、肌醇半乳糖苷合成酶、蔗糖合成酶、棉子糖合成酶、水苏糖合成酶和毛蕊花糖合成酶等参与了棉子糖系列寡糖的生物合成过程。

Transcriptionally active genes have ___ level of DNA methylation when compared to methylation of inactive genes.

C IPTG 与 lacI 基因的产物结合，抑制它的活性E IPTG 作为β-半乳糖苷酶的别构效应物，直接刺激它的活性

Raffinose family oligosaccharides are among the most widespread low_molecu lar_mass α_galactosides in seeds, mainly includes raffinose, stachyose, verbascose.

许多植物正常性种子的发育伴随着棉子糖半乳糖苷系列寡糖的累积，这些糖的累积已被认为在种子脱水耐性获得、种子活力、糖的运输及植物的抗冷驯化等过程

Maybe it is a new member of b-galactosidase family. bin2a mrna is upregulated by androgen and also epididymis-specific, majorly in caput epididymides.

所以，bin2a可能是b-半乳糖苷酶家族的新成员。bin2a表达受雄激素上调，其表达的组织专一性也很高，只在大鼠附睾有表达，并主要在附睾头部。

Methods In a series of cultured RPE cells, a standard beta-galactosidase histochemistry technique and MTT assay were performed to detect the activity of beta-galactosidase on a varying number (5, 10, 20) of population doublings and age (26, 44, 57) of the donator.

在培养的RPE细胞中，以传代次数（5、10、20）和取材供体的年龄（26、44、57岁）分组，进行标准化的β-半乳糖苷酶活性和细胞增殖能力检测。

RESULTS: Stable telomerase activity could be detected in the transfected fibroblasts and no signs of cell senescence were found in the fibroblasts cultured for more than 50 doublings.

结果 转染 h TERT的人成纤维细胞能稳定表达端粒酶活性，培养超过 5 0代后细胞仍保持β-半乳糖苷酶阴性。

The expression of p16INK4a protein was tested by immunochemical assay, and the life span in vitro of nasopharyngeal epithelial cells was calculated as population doublings.

我们应用老化相关半乳糖苷酶染色检测SA-β-Gal活性的表达情况，并利用免疫组化测定p16INK4a蛋白的表达。

Objective To determine the distribution and influence of lysosomal neuraminidase, protective protein/cathepsin A and β-galactosidase in the inner ear of the mouse, and to observe their auditory alterations in enzyme deficiency.

目的：研究溶酶体神经氨酸酶(neuraminidase， Neul)、保护蛋白／组织蛋白酶A(protective protein/cathepsin A， PPCA)和β-半乳糖苷酶(β-galactosidase，β-gal)在小鼠内耳的分布及相互影响，观察各自酶缺乏时的听功能改变。

Xanthus. In addition,β-galactosidase activity of ZC16-18 was detected by X-gal assay and the blue color developed was used to mark the colony growth. Time of colour showed that MXAN1334 gene was expressed in the early stage in M.

通过X-gal检测突变株ZC16-18中β-半乳糖苷酶酶活，实验结果显示，含有X-gal的平板上培养的ZC16-18菌落呈现蓝色，表明MXAN1334基因能够表达；颜色呈现的时间分析结果显示，MXAN1334基因表达时间较早。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
