Among the wide range of methods and expression hosts available for the heterologous production of recombinant proteins, insect cells are ideal for the production of complex proteins requiring extensive posttranslational modification. This review article provides an overview of the available insect-cell expression systems and their properties, focusing on the widely-used Baculovirus Expression V...

background the development of an effective subunit vaccine against brucellosis is a research area of intense. but optimization of recombinant proteins production in escherichia coli and content of endotoxins associated with final recombinant proteins are very important. objectives in the present study, expression and purification of brucella melitensis rhsp and rtf were optimized to reduce endo...

Application of plant expression systems in the production of recombinant proteins has several advantages, such as low maintenance cost, absence of human pathogens, and possession of complex post-translational glycosylation capabilities. Plants have been successfully used to produce recombinant cytokines, vaccines, antibodies, and other proteins, and rice (Oryza sativa) is a potential plant used...

Treatment with 2 mM CuSO4 was used to induce a Drosophila melanogaster metallothionein (Mtn) promoter that had been cloned into a recombinant baculovirus. Careful study revealed that the Mtn promoter functioned as an inducible, if somewhat "leaky" promoter within the context of baculovirus-infected cells. In the process of generating a recombinant-baculovirus, it was discovered that post-transf...

Plants are increasingly used as alternative expression hosts for the production of recombinant proteins offering many advantages including higher biomass and the ability to perform post-translational modifications on complex proteins. Key challenges for optimized accumulation of recombinant proteins in a plant system still remain, including endogenous plant proteolytic activity, which may sever...

Many examples of a successful application of plant-based expression systems for production of biologically active recombinant proteins exist in the literature. These systems can function as inexpensive platforms for the large scale production of recombinant pharmaceuticals or subunit vaccines. Hemagglutinin (HA) is a major surface antigen of the influenza virus, thus it is in the centre of inte...

The development of monitoring methods for assessing the physiological state of microorganisms during recombinant fermentation processes has been encouraged by the need to evaluate the influence of processing conditions in recombinant protein production. In this work, a technique based on microscopy and image analysis was developed that allows the simultaneous quantification of parameters associ...

Background: Enterocin-P of Enterococcus faecium P13 (EntP) is of great interest as a food preservative and medicine due to its non-toxicity and broad antimicrobial spectrum in various pH, as well as its excellent thermal stability. However, recombinant production of EntP is still in laboratory because of low productivity and complex purification process. Objectives: In this study, we aimed to ...
