چکیده

The genome of hepatitis A virus (HAV) was reverse transcribed into cDNA and molecularly cloned. cDNA clones coding for the capsid protein VP1 that carries the major HAV antigen were cloned into the expression vector pUR290 and expressed in Escherichia coli. The recombinant fusion protein reacted in an immunoblot with rabbit anti-HAV serum, suggesting that it possesses HAV antigenicity.

Cloning and Expression of Coxsakievirus B3 Viral Protein-1 in E. Coli

Viral protein-1 (VP1) is a major capsid protein of Coxsakievirus B3 (CVB3) that plays an important role in directing viruses towards permissive cells and acts as a main antigenic site of the virus in eliciting of host immune response, hence it seems VP1 can be considered as a vaccine candidate against CVB3 infection. In this study, cDNA of VP1 was prepared, cloned into pET expression vector and...

Cloning and expression of fragment of the rabies virus nucleoprotein gene in Escherichia coli and evaluation of antigenicity of the expression product

Rabies virus nucleoprotein (N protein) encapsidates genomic RNA of the virus and forms the viral ribonucleoprotein complex. These N proteins represent highly organized structures which activate proliferation of B cells and production antibodies against the N protein. In addition to the B cell, the rabies virus N protein has been shown to induce potent T helper cell responses resulting in a long...

     Foot-and-mouth disease (FMD) is an extremely infectious and occasionally fatal viral disease with a rapid onset and a short course that affects cloven-hoofed animals and results in considerable financial losses. For this reason, availability of more reliable and efficient vaccines against Foot-and-mouth disease virus (FMDV) is felt as a necessity. The purpose of this study is to develop a ...

Effect of IL-2 co-expressed or co-inoculated with immuno-dominant epitopes from VP1 protein of FMD virus on immune responses in BALB/c mice

Objective(s): The results of studies on vaccine development for foot-and-mouth disease (FMD) virus show that the use of inactivated vaccines for FMD virus is not completely effective. Novel vaccinations based on immuno-dominant epitopes have been shown to induce immune responses. Furthermore, for safety of immunization, access to efficient adjuvants against FMD virus seems to be critical.Materi...

Overexpression of Full-Length Core Protein of Hepatitis C Virus by Escherichia coli Cultivated in Stirred Tank Fermentor

The mature core protein of the Hepatitis C virus (HCVC173) carrying pelB as a signal peptide (PelB::core) was overexpressed in Escherichia coli as 18% and 23.3% of the host’s total protein, in flask and fermentor cultivation, respectively. A final specific yield of 25 ± 1 mg HCVC173/g dry cell weight and an overallproductivity of 51±1 mg HCVC173/l/h were obtained in the stirred-tank ferme...
