No trace of any newly expressed protein band was noticed in supernant as well as in the cells by sds - page, except the verification of the substitution of beta - galactosidase gene ( the lose of galactosidase protein band ), which is a selective marker of the wild - type virus. elisa test results suggested the expression of egf in cells, but not in culture supernant. the quantitative calculation suggested the expressed egf was about 6 - 7 u g ( as egf standard ) per flask ( 2 > < 106 cells ) in the cellular extract
將重組病毒rbmbacph - egf以10moi感染bmn細胞， 72小時后收集培養細胞和上清；培養上清和經超聲波處理的細胞樣品elisa檢測發現胞內樣品中存在能與egf抗體免疫反應的產物，粗略估計表達量約6 7 g 2 10 ~ 6個細胞（相當于egf標準品） ；重組病毒rbmbacph - egf穿刺接種5齡家蠶幼蟲，每隔24h收集蠶血淋巴，經elisa檢測發現第4天表達量最高，根據egf標準曲線計算蠶血淋巴的表達量約32 g ml ； elisa定性實驗還發現正常蠶血也存在與egf抗體間交叉反應的物質。Samples for strontium isotopic screened were selected by way of the test of cathodoluminescence, observation of thin sections, and analysis of sr and mn. the mn / sr value of all samples presented in this paper are less than 2, and the cathodoluminescence is dull, however, the samples from the cambrian underwent diagenetic alteration to a certain degree, and the plotted points of the thickness and 87sr / 86sr value are somewhat discrete. the strontium isotope evolution curve drawn from the data with relatively low 87sr / 86sr value are consistent with other curves based on samples from different areas of the world, supporting the notion of global consistency of strontium isotope composition of marine carbonates
根據鋸同位素地層學的基本原理，利用已有的鋸同位素演化曲線，筆者確定重慶秀山寒武系剖面寒武系底界、下一中寒武統界線和中一上寒武統界線都應適當下移；另外嘗試確定了重慶秀山寒武紀剖面一些關鍵點的年齡，累積厚度1380m處的年齡為503 ? 509ma ，累積厚度1900m處的年齡約為500ma ，這對秀山寒武系剖面下、中寒武統和中、上寒武統界線的確定具有參考價值。
