conclusions our results showed that the recombinant protein produced by the pbad vector in the escherichia coli system was very efficient. background nontypeable haemophilus influenzae (nthi) is a significant pathogen in children, causing otitis media, sinusitis, conjunctivitis, pneumonia, and occasionally invasive infections. protein d (pd) belongs to the minor outer-membrane proteins of h. in...
Background and Aims: Q59L mutant of L-asparaginase enzyme from Escherichia coli (E. coli) has been introduced with lower side effects. This version of the enzyme might have potential applications in the treatment of leukemia patients. We utilized SHuffle T7 strain of E. coli, to produce the mutant enzyme in the presence of chaperone molecules. Materials and Methods: Q59LAsp gene was cloned in...
lyme borreliosis is a tick-born disease caused by the spirochete borrelia burgdorferi. the aim of this research was molecular typing of different strains of b. burgdorferi and protective efficacy of outer surface protein in animal model. seven strains of b. burgdorferi isolated from skin and csf of lyme disease patients were compared using pcr- rflp as well as dna and amino acid sequences. the ...
Chicken infectious bronchitis virus (IBV) causes severe respiratory and renal dysfunction in chickens. In the present study, we used reverse transcription-polymerase chain reaction (RT-PCR) to amplify the nucleocapsid (N) protein gene of strain Massachusetts (Mass) H120 of IBV that is commonly used in the vaccine production in Iran. The PCR product with the expected size of 1.2 kb was cloned in...
Panebra, A., S.-X. Ma, L.-W. Zhai, X.-T. Wang, S. G. Rhee, and S. Khurana. Regulation of phospholipase C-g1 by the actin-regulatory protein villin. Am J Physiol Cell Physiol 281: C1046–C1058, 2001.—The actin-regulatory protein villin is tyrosine phosphorylated and associates with phospholipase C-g1 (PLC-g1) in the brush border of intestinal epithelial cells. To study the mechanism of villin-ass...
background: the rh antigens are expressed as parts of a protein complex in the rbc membrane. this complex is a tetramer, consisting of two molecules of rhag and two molecules of rh proteins. to express rhd in rbc membrane, expression of rhag is essential. this co-expression only occurs in the erythroid lineage. k562 cell line has an erythroid lineage. materials and methods: cord blood was used ...
this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...
objective(s):multi-epitopic protein vaccines and direction of vaccine delivery to dendritic cells (dcs) are promising approaches for enhancing immune responses against mutable pathogens. escherichia coli is current host for expression of recombinant proteins, and it is important to optimize expression condition. the aim of this study was the optimization of multi-epitopic hiv-1 tat/pol/gag/env ...
background: cryptosporidium parvum is a parasitic protozoan that functions as important causative agent of diarrhea in human and animals. the host's immune response to surface antigens of c. parvum has been previously demonstrated. in this respect, the role of humoral immunity in the development of host protective immunity against this protozoon has been well demonstrated. methods: the effe...
مقدمه : توبرکلوزیس (tb) یکی از مشکلات اصلی سلامت عمومی در جهان است. در حال حاضر تنها واکسن موجود برای آن یک سویه ضعیف شده bcg است. ولی کارایی این واکسن مورد تردید قرار گرفته است. بنابراین واکسن های موثرتر علیه tb مورد نیاز هستند. در حال حاضر، اجزای کمپلکس آنتی ژن 85 میاکوباکتریوم توبرکلوزیس (ag85a, ag85b,ag85c) به دلیل ترشحی و ایمنودامیننت بودن از آنتی ژن ها پروداکتیو نوید بخش برای ساخت واکسن...
