沉性卵 的英文怎麼說
中文拼音 [chénxìngluǎn]
沉性卵
英文
demersal egg-
The results from sds - page presented that there were three female specific protein subunits with molecular weights of 123 kd, 120 kd and 91 kd, respectively. we can conclude the higher molecular compose of two subunits ; the results from two dimension electrophoresis showed the isoelectric points of two female - specific spots with molecular weight of about 120kd were 5. 5 and 5. 7. immunodiffusion reactions demonstrated that vg existed both in female fat body and hemolymph, which as vn was deposited in the ovary, while not in the male
Page電泳結果表明：麗蠅蛹集金小蜂明顯存在2條雌特異性帶-卵黃蛋白，分子量分別為181kd和136kd ； sds - page電泳分析：存在3條雌特異性帶，其分子量為123kd 、 120kd和91kd ，由此，可推定卵黃原蛋白（ vitellogenin ， vg ）和卵黃磷蛋白（ vitellin ， vn ）由2個蛋白組成，其中分子量較大的蛋白由2個亞基組成；雙向電泳結果顯示，在120kd附近有兩個特異性點，其等電點為5 . 5和5 . 7 ；雙擴散表明，麗蠅蛹集金小蜂卵黃磷蛋白的抗血清與雌隱成蟲蟲體、脂肪體、血淋巴和卵巢勻漿液均有免疫沉澱反應，而與雄蜂血淋巴無免疫反應，說明了vg與vn具有免疫同源性，是雌特異性蛋白，且由脂肪體合成。The brine shrimp he was prepared and purified by 67 % ammonium sulfate precipitation, deae - sepharose fast flow ion - exchange chromatography, and sephacryl column gel - filtration, and its biochemical and enzymological properties were identified in this study. it was found that the deduced molecular weight of he in sds - page is about 98. 5 kda, and its proteolytic activity was optimized at ph of 7. 5 - 8. 5 and at temperature of 40, respectively
我們利用67硫酸銨沉澱、 deae - sepharosefastflow陰離子交換柱層析和sephacryl凝膠過濾柱層析，並以酪蛋白為其蛋白酶水解活性的檢測底物、以卵膜為其卵殼裂解活性的特異性底物，從鹵蟲胚胎孵化液中分離純化出了鹵蟲的孵化酶分子，其在sds - page電泳中的分子量約為98 . 5kda 。
