菌落形成率 的英文怎麼說
中文拼音 [jūnlàxíngchénglǜ]
菌落形成率
英文
colony forming efficiency-
Culture of mg7 hybridoma cells and detection of antigen - binding affinity of mg7 mab by elisa 2. construction and identification of mg7 recombinant phage antibody library mrna was isolated from cultured mg7 hybridoma cells and converted into cdna ; the variable fragments of heavy and light chain were separately amplified and assembled into scfvs with a specially constructed dna linker by pcr. the scfvs dma was ligated into the phagmid vector pcantabse and the ligated sample was transfered into competent e. co / / tg1 to generate a bacterial form of mg7recombinant phage antibody library ; volume and recombinant ratio of the library were evaluated by means of bacterial colony counts and restriction analysis ( ecor i and hind iii )
Mg _ 7重組噬菌體抗體庫的構建及鑒定從培養的mg _ 7雜交瘤細胞中提取並分離mrna ,反轉錄成cdna ;利用pcr分別擴增mg _ 7單抗的重鏈及輕鏈可變區基因,並通過? dna連接子將二者連接起來形成mg _ 7單鏈抗體基因;將mg _ 7單鏈抗體基因插入pcantab5e ;將連接產物轉化感受態tg1大腸桿菌,制備細菌形式的mg _ 7重組噬菌體抗體庫;通過菌落計數和限制性酶切分析( ecor和hind )評估mg _ 7重組噬菌體抗體庫的容量和重組率。First, after investigation of two original strains " biological characteristics, we studied the main influence factors on protoplasts formation and regeneration in s. mycarofaciens and s. erythreus, and determined the best protoplasts formation and regeneration conditions of two original strains. the former shake - cultured in s " medium at 28 ?, 220r. min ~ ( - 1 ) for 24h, lysised by 3mg / ml lysozyme, keeping warm at 32 ? for 50 ~ 60min, regenerated on r _ ( 5 " ) medium, 28 ? for 5 ~ 6d. the latter used two - step culture, then used img / ml lysozyme keeping warm at 37 ? for ih ; the protoplasts were plated on r5 " regeneration medium at 28 ? for 5d
首先在對兩親株的生物學特性進行了鑒定后,考察了影響兩親株原生質體形成和再生的主要因素,確定了生米卡鏈黴菌和紅黴素鏈黴菌原生質體形成及再生的最佳條件:前者用s培養基,在28 、 220r . min ~ ( - 1 )培養24h后,用3mg ml的溶菌酶在32恆溫酶解50 60min ,得到的原生質體在乾燥的r5培養基上28倒置培養5 6天,可得到再生率在20左右的再生菌落;後者採用二級菌絲培養,用1mg ml的溶菌酶在37恆溫酶解1h左右,得到的原生質體也在乾燥的r5培養基上28倒置培養5天,即可得到再生率在20左右的再生菌。
