  2. In order to produce monoclonal antibodies, first, several v. dahliae isolates were grown in liquid czapeak medium, after rinsing mycelia and eliminating zoospores, the fungal tissue was homogenized with the pestle in liquid nitrogen and then transferred to test tubes and was centrifuged in tris - hcl buffer

    在制備抗原的過程中,首先液體振蕩培養了若干株棉花黃萎病菌,經過沖洗除孢子、液氮研磨,用tris - hcl抽提,再離心制得菌絲蛋白提取液,可作為電泳樣品。
  3. At first, 1. 67 u g per well mcab all was coated on three wells of a plate, and then 1. 5 x 1011 phage virion was diluted and added, after incubating with the target, wash away unbound phage by tbst ( 0. 1 % tween - 20 ), the bound phage was eluted with ph 2. 2 tris - gly buffer and amplified, the specially bound phage was enriched by taking through addition binding / amplification cycles. ln the following cycles, the stringency of panning can be increased by raising the concentration of tbst or decreasing that of mcab all, collecting and titering the washing phage of last time and output phage in each round, the selective ratio and the false positive rate of each round were worked out, the gradually increasing of selective ratio and decreasing of positive rate shows that the panning was effective. after 4 rounds of panning, 11 phage clones were selected after competitive - ellsa, the dna samples of 8 positive clones and 1 negative clone were sequenced and all the foreign peptides inserted was also deduced, a clear consensus binding sequence emerged

    在本實驗中,利用隨機12肽庫對抗豬瘟病毒( classicalswinefeverviruscsfv )糖蛋白me2的單抗a11進行表位篩選,經過四輪篩選以後,隨機挑取11個克隆作競爭- elisa檢測,結果表明,所挑11個克隆中,有9個克隆能對me2蛋白和a11反應產生抑制作用,抑制率最高可達64 ; dna測序以後經過dnastar軟體分析,發現它們的核心序列為anwralsl ,該核心序列與豬瘟病毒e2蛋白的28 - 35位氨基酸ttwkeysh具有同源性;夾心- elisa檢測和western - blotting試驗均證明所挑陽性克隆能被a11所識別;人工合成含核心序列的多肽經間接elisa試驗證實,也能被a11識別。
  4. However for the closed stomata, induced by aba, the distribution density of particles in gcv is greatly reduced with the obviously enlarged volume, b ) buffers regulate ph of in vitro gcv sap in the tip of micro - capillaries : certain amount of buffer ( mes - tris ) is filled from the tip of micro - capillaries beforehand, and the ph of gcv sap that is sampled by the same micro - capillary sh ould be regulated by the buffer

    觀察結果與本試驗室已發表的氣孔開放過程的實驗結果一致:開放態氣孔保衛細胞液泡所含顆粒狀物的線度極小(平均直徑10nm ) ,且分佈密度極高,而經aba處理的關閉態氣孔保衛細胞液泡所含顆粒狀物的線度很大(平均直徑50nm ) ,分佈密度很小。
  5. Western blot analysis we treated 200 fertilized eggs in a series of steps including lysing them in l0ul of lysis buffer ( 50mm tris - hcl ph 7. 5, 250mm nacl, 5mm edta, imm dtt, 0. 1 % triton, 50mm sodium orthovanadate, looug / mg pmsf and tpck, 50ug / ml tlck, 1 ug / ml leupeptin pepstatin and aprotinin ), frozing them below - 70, and then thawing them at room temperature for 10 min
