newcastle disease (nd) is one of the most serious illnesses of chickens. live vaccines are widely used to prevent chicken from the disease all over the world. to access the effective and potentiate nd vaccine, a homogenous subpopulation from lasota strain was selected following cultivation of the virus on primary chicken embryofibroblast (cef) cells. pathogenicity indices and molecular characte...
Background: Infeliximab is a form of chimeric antibody which neutralizes the most important inflammatory cytokine, TNF-a, in inflammatory disorders. The aim of current study was to pilot expression of chimeric infliximab in Chinese Hamster ovary (CHO) cells. Methods: In this research study, pVITRO2-neo-mcs vector that consist of infliximab light chain and heavy chain was used to transform in...
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...
In this study, Rhizomucor miehei ?-1,3-1,4-glucanase gene was expressed under the regulation of AOX1 promoter in Pichia pastoris expression system, and clone providing highest production level determined. The codon-optimized ligated into vector pPICZ?A transferred competent P. KM71H cells. Thirty transformants were selected from plates containing different concentrations zeocin cultured test tu...
The rapid development of new technologies for the high throughput (HT) study of proteins has increased the demand for comprehensive plasmid clone resources that support protein expression. These clones must be full-length, sequence-verified and in a flexible format. The generation of these resources requires automated pipelines supported by software management systems. Although the availability...
Affinity tag systems, possessing high affinity and specificity, are useful for protein detection and purification. The most suitable tag for a particular purpose should be selected from many available affinity tag systems. In this study, we developed a novel affinity tag called the "RAP tag" system, which comprises a mouse antirat podoplanin monoclonal antibody (clone PMab-2) and the RAP tag (D...
Background: Human CD34 is a transmembrane glycoprotein which is expressed in human hematopoietic stem cells (HSCs) and the small- vessel endothelial cells of a variety of tissues. CD34 plays a critical role as a marker for diagnosis and classification of leukemia. Anti CD34 antibodies are used for isolation and purification of HSCs from bone marrow, peripheral blood and cord blood. Objective: ...
We have isolated and characterized a neutral phosphatase gene, phoN, from Treponema denticola ATCC 35405. The gene was isolated from a T. denticola clone bank constructed in the medium-copy-number plasmid vector pMCL19. Subcloning and nucleotide sequencing of the DNA insert from one phosphatase clone, pTph14, revealed that the activity corresponded to an open reading frame consisting of 1,027 b...
To carry out the immunological experiments on the serum of Multiple Sclerosis (MS) patients, based on a correlation between Borrelia burgdorferi infection and contracting MS autoimmune disease the outer surface protein D (OspD) of the bacterium was expressed and purified. A clone containing the OspD gene in pET11a expression vector under the control of T7 promoter was transformed to the bacteri...
