Periplasmic space

Sperm cell was surrounded by discontinuous periplasmic space in rice mature pollen grain .

在稻成熟花粉粒中，精细胞被不连续的电子透明的周质空间所包围。

The study also discovered that while the recombinant alkaline protease was secreted into the periplasmic space of E.

研究发现，重组的碱性蛋白酶在进入大肠杆菌周质空间时可能存在前肽自动脱落的现象。

Heterologous proteins could be expressed directly in the cytoplasm , secreted into the periplasmic space or extracellular medium .

大肠杆菌中外源蛋白可定位于胞内、周质或胞外培养基中。

The recombinant protein , about 10 % of the total bacterial protein in volume , was secreted to the periplasmic space of the cell .

重组蛋白位于细菌外周质，表达量约占菌体总蛋白的10%。

ELISA tests showed that the antigentic activity of secreted HDAg in periplasmic space is 70 % of the total , its ELISA titer and specific activity are higher than 1:32,000 and 10,000 ELISA unit / mg of protein expressed .

ELISA分析表明，分泌性HDAg的活性优于包涵体中的HDAg，分泌性HDAg的ELISA滴度高于1：32000比活性为10000ELISA滴度／mg蛋白；

Coli strain BL21 ( DE3 ), and gene expression was induced by IPTG . The target proteins were directed into the periplasmic space by the staphylococcal protein A ( SPA ) signal sequence preceding the RGD hirudin gene .

由于RGD水蛭素嵌合基因上游连接了金黄色葡萄球菌蛋白A（SPA）的信号肽序列，在IPTG诱导下两种嵌合分子都获得了分泌表达，表达产物主要集中在细胞周质空间。

Most of the β - glucosidase activity was located on the cell surface of C. hutchinsonii from the enzyme assay , although the genomic analysis showed that all the candidate β - glucosidases were predicted to be located in the periplasmic space .

虽然基因组序列分析预测可能的β-葡萄糖苷酶都位于细胞周质，但是多次酶活实验表明大部分的β-葡萄糖苷酶活力位于细胞表面。
