大豆主要过敏原β-伴大豆球蛋白β亚基的抗原表位分析及分段克隆
Analysis of antigenic epitopes and cloning of soybean major allergen β-conglycinin beta-subunit
摘要
Abstract
The model of tertiary ofβ-conglycinin beta-subunit was constructed by the bioinformation tool SWISS-MODEL,and the conformational epitopes were predicted by DiscoTope 2.0 server.The overlapping fragments of β-conglycinin beta-subunit genes were amplified by PCR and inserted into pMD-18T vector,then preserved into competent cell of Escherichia coli JM109.The recombinant plasmids were evaluated by blue-white selection,PCR and double enzyme digestion,and DNA sequence analysis showed that the cloned sequence was the very fragment designed.The successful cloning of the genes can provide a reference for the study of the expresstion of β-conglycinin beta-subunit and screening of antigenic epitopes.关键词
