Background and Objective: Botulinum neurotoxin type A, structurally consists of a 50KD light chain and a 100 KD heavy chain linked by a disulfide bond. The protein can further be divided into three functional domains of which catalytic domain corresponds to the light chain. In this research we aimed to produce recombinant catalytic domain in order to obtain a protective protein. Materials and M...
Background: Targeting of CD20 antigen with monoclonal antibodies has become the mainstay in the treatment of non-Hodgkin's lymphomas and immunotherapeutic depletion of malignant B cells. Accessibility of antigen is one of the crucial factors in development of monoclonal antibodies against this antigen. One major problem in expression of full length CD20 is aggregation and misfolding. Therefore,...
Recent studies suggest that reducing the induction temperature would improve the quality of some recombinant inclusion bodies (IB) by providing a native-like secondary structure and leading to an improvement in protein recovery. This study focused on optimizing the solubilization condition of Reteplase, a recombinant protein with 9 disulfide bonds. The influence of lowering induction temperatur...

Background: Newcastle disease is a major avian disease that causes enormous economic loss in poultry industry. There have been a number of reports on the suitability of plant-based recombinant vaccine against this disease. Fusion (F) and hemagglutinin-neuraminidase (HN) epitopes of the Newcastle disease virus (NDV) represent the major immunogenic sites for development of recomb...
Background : The aim of the present study was to identify a suitable cell line for studies of recombinant protein production in eukaryotic system. After transfection, altered expression levels of RNA and its target protein were analyzed. Materials and Methods: To investigate the in vitro expression of E6 protein of human papillomavirus type 16 in cell culture, the plasmid pcDNA3-E6, and two di...
ارزیابی و مقایسه تیتر آنتی بادی علیه پروتئین های نوترکیب منفرد، مخلوط و کایمر CTXB، TCPA وTCPA CTXB-
Background: Cholera as diarrheal illness is one of the most important causes of death and people's disability in different societies. Colonization factor pili (tcpA) and cholera toxin are the most important factors in the pathogenesis of Vibrio Cholera. B subunit of cholera toxin (ctxB) and tcpA have the ability to induce immune responses. The aims of this study was production of CTXB, TCPA, CT...
objective: antigen 85 complex of mycobacterium tuberculosis includes three immunogenic proteins which are important tb vaccine candidates. the use of these protein as a component of subunit vaccines, as a part of dna vaccines or recombinant bcg boosters, enhances their recombinant production. recombinant production of these mycobacterial proteins located in the cell wall somehow differs from th...
Abstract Background and purpose: Clostridium botulinum neurotoxins are the most potent toxins that cause the life-threatening botulism syndrome in humans and animals. Researches have shown that the binding domain of the botulinum neurotoxin type E has a high immunogenicity effect that could be used as an efficient recombinant vaccine. The recombinant vaccines are not potent enough to stimulate...
Structure- and Design-Based Difficulties in Recombinant Protein Purification in Bacterial Expression
Protein purification is not a simple task. Yet, overexpression at bacterial systems with recombinant modifications brings further difficulties. Adding tag, an affinity label, and expressing particular domains of the whole protein, especially hydrophobic sections, make challenging process. folding pattern may perturb N- or C-terminal tag this terminal preference lead to poor yield. Codon optimiz...
