Introduction: Plant ribosome inactivating proteins act as N-glycosidase enzyme and produce by several family of Caryophyllaceae such as Saponaria Officinalis. Different Isoforms of RIPs expressed by Saponaria Officinalis. SO6 isoform depurinate Adenine 4324 in the conserved GAGA loop of 28SrRNA and disrupts protein synthesis. The aim of this study was expression of SO6 isoform in E.coli and inv...
Abstract Background and objective: Hepcidin is a cystein-rich antimicrobial peptide, which is secreted by the liver. It fights against wide spectrum of bacteria, viruses and fungi and it is a major regulator of iron homeostasis. Today, scientists have made many efforts on the production of hepcidin. Baculovirus expression system is one of the best eukaryotic expression systems for production of...
In recent years, the number of recombinant proteins used for therapeutic applications and industry has increased dramatically. Recombinant proteins are produced in many host organisms (microbial, insect, plant and mammalian cells). There are many factors to consider when choosing the optimal system for protein expression and purification including the mass, purity or solubility of the recombina...
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 ...
Background and Objectives: Laccase is the most abundant member of protein family that catalyzes the oxidation of substituted phenols. Laccases are used as biocatalysts for decolorization and bleaching in dye industries, detoxification in environment, and juice clarification in food industries. The present study aimed at producing recombinant laccase, purifying with high yield and fold, and char...
conclusions: the recombinant baculovirus constructed in this work has proper characteristics to produce h5n1 influenza virus-like particles in sf9 cells. results: restriction map of pfastbacihnm1 plasmid confirmed the fidelity of the clone. the pcr carried out on the recombinant bacmids as template indicated that a proper homologous recombination has occurred between pfastbacihnm1 donor plasmid...
tetanus is a disease caused by tetanus toxin, a potent inhibitor for the release of inhibitory neurotransmitter in the central nervous system that causes spastic paralysis. fragment c (52 kd) of this toxin is responsible for binding to the neuronal membrane. for this reason, and also its non toxigenic and immunogenic nature, this fragment might be ideal for new vaccine development. presently, w...
a sweet water-soluble protein that reminds stable over wide ranges of temperature and ph, brazzein has various applications. its tastes like cane sugar but have no calories. however, the extraction of brazzein from its natural source is expensive and not applicable. in this study we used recombinant dna technology to provide an alternative option for cheaper mass production of brazzein. a brazz...
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...
results cloning was confirmed by pcr and restriction digestion. rt-pcr and sds-page represented expression of kgf in e. coli. the optimized expression was achieved 16 hours after induction with 0.3 mm iptg at 37°c in luria broth (lb) containing kanamycin. the 18 kda protein was confirmed by western blotting, using anti-his antibodies. conclusions the result of the present study indicated that e...
