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。The main subject in this paper contain : this paper studied the characters of system of spaceflight test control, and put forward the system characteristic and function interface in new system of spaceflight test control according to the evolution of sdr. and then analyzed the project demand of telemetering digital diversity receiver
