objective(s) tuberculosis (tb) is the leading cause of mortality among the infectious diseases, especially in developing countries. one of the main goals in tuberculosis research is to identify antigens which have the ability of inducing cellular and/or humoral immunity in order to use them in diagnostic reagents or vaccine design. the aim of this study was to clone and express the tb'0.4 ...

ATP-dependent DNA unwinding activity has been demonstrated for recombinant archaeal homohexameric minichromosome maintenance (MCM) complexes and their yeast heterohexameric counterparts, but in higher eukaryotes such as Drosophila, MCM-associated DNA helicase activity has been observed only in the context of a co-purified Cdc45-MCM-GINS complex. Here, we describe the production of the recombina...

expressions of recombinant proteins for different applications are important objectives in molecular biotechnology; however, expression of some recombinant proteins is difficult. several methods have been designed for expression of these proteins. the aim of this study was to construct a vector containing mtb32c fragment of mycobacterium tuberculosis (m.tuberculosis) as a fusion partner in orde...

background: regarding that accurate diagnosis of human hydatidosis still needs more investigations, the present study was conducted to clone, express, and evaluate the gene encoding agb subunits (egagb16 kda) from echinococcus granulosus (iranian g1 strain) and its evaluation by elisa test. methods: dna was extracted from protoscoleces and was utilized by pcr for strain identification. total rn...

chlamydia trachomatis is one of the main causes of sexually transmitted diseases (stds) such as  prostatitis and epididymitis in men and cervicitis, endometriosis, vaginitis and ureogenital tract infections in women.  serological tests with sensitivities related to specific antigens are commonly used as  routine laboratory tests for diagnosis of chlamydia. in this research the chlamydia major o...

background and purpose: brain-derived neurotrophic factor (bdnf) is present in the hippocampus and cerebral cortex in high concentrations and has an important role in development, maintenance and regeneration of the nervous system. the aim of this study was to produce active bdnf in e.coli using transforming plasmid. methods: to construct an expression plasmid of bdnf, a gene coding for it was ...

Background: Vaccines based on virus-like particles are effective against Human Papilloma Virus (HPV) infection; however, they have not shown a therapeutic effect against HPV-associated diseases. New immunotherapy strategies based on immune responses against tumor antigens can positively affect the clearance of HPV-associated lesions. Objective: To generate two therapeutic fusion DNA vaccines (o...

This Application Note describes the evaluation of the Agilent 2200 TapeStation system and the Agilent Genomic DNA ScreenTape assay for the quantitative and qualitative analysis of a variety of genomic DNA samples before subsequent
