查询词典 methylation

To address this question in an unbiased and genome-wide manner, we developed a new method, methylation-specific digital karyotyping, and applied it to epithelial and myoepithelial cells, stromal fibroblasts from normal breast tissue, and in situ and invasive breast carcinomas.

为了能无偏向地并在基因组范围解答这个问题，我们开发了一种新的方法——甲基化特异性数字染色体组型，并将这一方法应用于上皮细胞和肌肉上皮细胞、正常乳腺组织来源的基质成纤维原细胞、原位及侵入性乳腺癌细胞。

With the inducing time prolonged, the amount of fusion protein increased, and the highest content amounted to 39. 14% of total protein. Different temperature (15℃, 25℃ and 37℃) could induce expression of fusion protein, and the higher inducing temperature was, the more total fusion protein and soluble fusion protein was produced. Most fusion protein was expressed in the cytoplasm and was soluble, a little of fusion protein was expressed in periplasm or expressed as inclusion bodies, and no fusion protein was found in culture. Furthermore, the results of in vitro enzymatic reaction suggested that the fusion protein could catalyze the methylation of theobromine.

随着诱导时间的延长，表达的融合蛋白产量逐渐增加，表达蛋白总量最高可达到菌体总蛋白的39.14％；在15℃、25℃和37℃三个不同的诱导温度下，均能诱导产生融合蛋白，而且产生的融合蛋白的总量及其可溶性部分所占比例均随诱导温度升高而增加；在菌体的各个部位中，融合蛋白主要在细胞质中以可溶的形式进行表达，有少量在外周质中表达或以包含体形式在细胞质中表达。

In order to find highly active pesticide, three series of 5--12-substituent-benzo phenanthridine derivatives were synthesized through the reaction of 2-methylbenzonitrile with dif-ferent aldehyde, and further dehydration with DDQ or N-methylation with NaH and CH3I, respectively.
