Guan xiaohong, et al. ( 1991 ) established a strain of monoclonal anti - idiotypic antibody np30 of schistosoma japonicum, whice is an internal image antigen of gut associated antigen ( gaa ), its antibody isotype is igm. np30 has a partial cross - reaction with soluble egg antigen ( sba ) and membrane associated antigen ( maa )
管曉虹等建立的日本血吸蟲單克隆抗獨特型抗體（ anti - id ， ab _ 2 ） np30是腸相關抗原（ gaa ）的內影像anti - id ，與可溶性蟲卵抗原（ sea ）有交叉反應，可替代蟲源性抗原用於血吸蟲病免疫診斷和抗病疫苗的研究。After the recombinant plasmid pcdna3. 1 / ts87 was identified by digestion of hindlll and bamh i, it transformed into cos7 by lipofectamine. expression product was identified by immunohistochemical method, sds - page and western - blot. the immunocytochemistry result has shown that specific brown - staining grains were found in the cytoplasm of cells transformed by recombinant plasmid versus not seen in cells transformed by pcdna3. 1 or normal cells ; the sds - page result has revealed that a band about 3 8kb was found in cell lysis transformed by recombinant plasmid versus not in cells transformed by pcdnas. l or normal cells ; the western - blot result has showed that only the band about 38kd was recognized by sera from rabbit infected by t. s artificially and sera from rabbit immunized with soluble antigen of t. s and with protein expressed by ts87 gene and by a monoclonal antibody of t. s
通過細胞的免疫組化，細胞裂解物的sds - page電泳， westem - blot分析檢測目的基因的表達情況。免疫組化結果顯示：重組質粒轉染的細胞質中有棕褐色顆粒，而空載體轉染細胞及正常細胞無此現象；細胞裂解物sds - page電泳結果顯示：只有重組質粒轉染的細胞在約38kd處有明顯的蛋白帶，這與理論計算的ts87基因表達蛋白的分子量為38kd基本一致； western - blot分析結果顯示：約38kd的蛋白帶能夠分別被旋毛蟲感染兔血清，成蟲蟲體可溶性抗原免疫兔血清， ts87基因原核表達蛋白免疫兔血清（ ts87血清）以及一株具保護性的旋毛蟲單抗特異識別。The characteristics of this method are : a, directly counting cell number without the influence of the metabolic state of the cells ; b, discrimination of target cells from effector cells in cell - mediated cytotoxicity assay ; c, less treatment step, and free - radioactivity ; d, high sensitivity and reliability. 2, using the above assay, immunofluorescent labeled technique, and flow cytometry, the pbmc proliferation, apoptosis, necrosis, cell cycle, activation, cytokines and membrane marker were detected. the results showed that the number of pbmc reduced, but the activity of pbmc increased dose - dependently ; the reduction of cell number resulted from necrosis and apoptosis ; the supernatant of k562 cell lines were not able to block the cell cycle, but to promote it ; the ratio of t cell subset and the expression of thl and th2 cytokines increased
結合以上創建的方法和免疫熒光流式細胞術，用k562細胞株可溶性分泌物（上清）對外周血單個核細胞（ pbmc ）進行培養以模擬體內微環境，然後分別從細胞增殖、凋亡、壞死、細胞周期、活性、細胞因子和表面抗原表達等方面進行研究，結果發現用腫瘤上清培養的pbmc細胞數量下降明顯，但同時對其有激活作用，且呈劑量依賴性；細胞數的下降主要是由細胞壞死和凋亡引起的，腫瘤上清對細胞周期沒有阻斷作用，反而略有促進作用； t細胞亞群比例增加，並促進表達th1 、 th2細胞因子。Piezoelectric sensing technique has been applied to many fields, including analytical chemistry, life science, environmental monitoring and surface sciences because of it ' s small size, high sensitivity, simplicity, low power consumption and broad sensing spectrum. piezoelectric immunosensors possess high selectivity provided by antibodies or antigens and sensitivity response directly to the mass change of proteins. immobilization technologies of biomolecules are of paramount importance in order to preserve their biological activity
壓電免疫傳感技術利用壓電晶體與抗原抗體特異性免疫反應結合的特徵，通常在壓電石英晶體表面先固定抗原（抗體） ，響應溶液中抗體（抗原）引起的質量、密度和粘度等性質的變化，它兼具有壓電質量響應的高靈敏性和生物化學反應的高特異性。Unfortunately, tumor cells can secrete immunosuppressor factors ( such as il - 10, tgf - p, vegf ) to interfere with dc maturation and function. to overcome tumor - mediated inhibition of dc maturation and function in vivo, immunopotentiating cytokines ( such as il - 7, il - 12 ) were used for gene - modification of dc, which has proven to be an efficient way to treat cancer in animal models
雖然有直接瘤內注射dc誘導抗腫瘤免疫效應的報道，但腫瘤局部往往是一個處于高度免疫抑制狀態的微環境，腫瘤細胞分泌的可溶性介質（如ill 、 tgf卜vegf等）能抑制dc的分化成熟，下調dc表面共刺激分子的表達和iliz的分泌，從而抑制dc的抗原提呈功能，亦對t細胞功能有顯著的抑制作用。Western blot and elisa assays indicated that fmdv vp1 gene was expressed in tobacco chloroplasts and accounted for 2 % ~ 3 % of the total soluble protein ( about 20 - 30 ( ig of chloroplast - expressed vp1 protein in 1 mg of total soluble protein )
Westernblot和elisa免疫雜交分析證明fmdvvp1抗原蛋白在煙草葉綠體中得到表達，表達量占可溶性總蛋白量的2 3 （ 1mg可溶性總蛋白含有20 30 g的vp1蛋白） 。分享友人
