چکیده

turnip curly top virus (tctv) is a member of the newly established genus turncurtovirus, family geminiviridae. development of an efficient detection system is necessary to study the biological characteristics of viruses. due to the superior efficacy of the serological methods for detection of plant viruses, in this research, with the aim to facilitate the process of immunological detection of tctv, coat protein (cp) gene of the virus was sub-cloned into prokaryotic expression vector pqe-60 and transferred into e. coli strain m15. following induction of cp expression, total protein was extracted and run onto 12.5% sds-page. an approximate 34 kda band corresponding to the tctv cp has been expressed in the prokaryotic host. this protein could be used as antigen to induce the antibody generation for the serological detection of tctv.

Cloning and evaluation of gene expression and purification of gene encoding recombinant protein containing binding subunit of coli surface antigens CS1 and CS2 from Enterotoxigenic Escherichia coli

Background & Objective: Enterotoxigenic Escherichia coli (ETEC) is a major causative agent of diarrhea. Enterotoxins and the colonization factors (CFs) are major virulence factors in ETEC infections. The bacterium binds to the intestinal epithelial cell surface through colonization factors and produces enterotoxins that cause excessive fluid and electrolyte secretion in the lumen of the intesti...
