As determined by SDS-PAGE and dcnsitometry, the overproduced proteins comprised up to 18.5% of the total bacterial protein.

通过SDS聚丙烯酰胺凝胶电泳检测表明，在实验室规模的发酵实验中，NAP-1/IL-8在大肠杆菌中的表达量可占菌体可溶性蛋白的10.9％；而在摇瓶培养中则占18.5％。

Albicans strains with fluconazole. Method: A series of 16 strains C. albicans from the same body were induced to form pseudo-hyphae in RPMI 1640 medium and DMEM medium at 37 癈 for twenty-four hours respectively. The pseudo-hyphae and yeast were counted and the ratio between pseudo-hypha and total cells was calculated. C. albicans strains were induced to form pseudo-hyphae in RPMI 1640 medium for seven days by transferring twelve times. The genome DNAs of the hyphal-form of C. albicans was cleaved by two restriction enzymes EcoR I and Bgl II, the products were electrophored and photoed.

以同一母体来源的白念珠菌CA-1～A-17(共16株)作为研究对象，采用RPMI1640和DMEM培养基，37℃培养24h诱导其假菌丝形成，记录不同观察时间时的菌丝相和酵母相细胞数，计算菌丝相白念珠菌形成率；以RPMI1640培养基，37℃连续传代培养7天(转种12次)后，分离菌丝相白念珠菌并提取其基因组DNA；以EcoRⅠ和BglⅡ消化菌丝相基因组DNA，消化产物进行琼脂糖凝胶电泳并拍照；用随机引物(5'…TCACCACGGT…3')扩增菌丝相基因组DNA，采用变性聚丙烯酰胺凝胶电泳分离扩增产物并拍照。
