released antigen 中文意思是什麼
-
Exosomes derived from human intestinal epithelial cell ( iec ) could be released from apical and basolateral sides and expressed mhc class i molecules, cd26, cd63 in basal conditions besides mhc class ii in inflammatory conditions. the data showed exosomes might be a mechanism of oral tolerance. exosome - like vesicles isolated from rat iec line, which were pulsed by antigens, were shown to induce antigen - spec
模型的建立和exosomes的分離與純化我們利用一種c57bl / 6小鼠的3lllewis肺癌細胞系作模型，將3ll細胞皮下注射到c57bl / 6小鼠，待3周時無菌取出腫瘤組織，剪碎後用dmem加10 %的血清在37 ， 5 %的czo中培養， 30小時后收集培養上清。 -
Constructed the fusion protein expression vector of echistatin, . and identify it by dna sequencing. the vector can express echistatin fusion protein at a high level, the fusion protein molecular weight is about 16000 da in sds - page analysis, and the fusion protein consists more than 30 % of total protein, the fusion protein has specific antigen - antibody reaction with rabbit anti - echistatin polyclonal antibody. the fusion protein include : hpk5. his + 6tag, and echistatin. echistatin can be released by cnbr cleavage
構建了echistatin融合蛋白表達載體，經dna測序鑒定正確后，溫控誘導表達，獲得了高效表達，表達產物經505一隊ge分析，分子量為16000oa ，符合預計的融合蛋白分子量，表達產物. ll 』菌體總蛋白的30 %以上， westem一blotting結果顯示，該日的蛋白能夠和echistatin多克隆抗體發生特異性抗原抗體反應，表明我們成功構建了eohistatin的高效融合表達克隆。
