[ 1 ] - بیان پروکاریوتی پروتئین کایمر سه تایی3M2e-HA2-NP حاصل از نواحی حفاظت شده پروتئینهای ویروس آنفلوانزای A/H1N1 در راستای دست یابی به واکسن زیر واحدی فراگیر

زمینه و هدف: ویروس آنفلوانزا A یک پاتوژن تنفسی مهم است که باعث بیماری و مرگ و میر گسترده در طول اپیدمی‌های فصلی و پاندمی ‌ها می‌شود. واکسن‌های رایج آنفلوانزا توانایی ایجاد ایمنی مؤثر در برابر سویه‌های مختلف ویروس آنفلوانزا را ندارند. طراحی واکسن‌های فراگیر با استفاده از آنتی‌ژن‌های حفاظت شده‌ی ویروس آنفلوانزا در جهت رفع این محدودیت می‌باشد. ناحیه بیرونی پروتئین M2 آنفلوانزا (M2e)، ساقه هماگلوتی...

[ 2 ] - بیان و خالص سازی پروتئین کایمر نوترکیب (3M2e-HA2) واجد نواحی حفاظت شده هماگلوتینین و پروتئین ماتریکس ویروس آنفلوانزا در راستای تولید واکسن زیرواحدی جهانی

Background and purpose: Influenza virus is one of the most important respiratory infectious agents. Viral antigenic variations are major problems for vaccine production process. At present, many researches have focused on conserved domains of influenza virus antigenic peptides for subunit vaccine development. Hemagglutinin small subunit (HA2) and the 23 amino acid extracellular N-terminal domai...

[ 3 ] - Cloning, expression and purification of hemagglutinin conserved domain (HA2) of influenza A virus, to be used in broad-spectrum subunit vaccine cocktails

Introduction: Influenza virus has several conserved peptides which have the capacity to be used as suitable candidates for appropriate and stable vaccine production against different types of influenza viruses. One of these peptides is HA2, the hemagglutinin stalk domain which mediates the membrane fusion and is conserved amongst different sub-types of influenza virus. This peptide is a good ca...

[ 4 ] - Comparison of Vero and MDCK cell lines transfected with human siat7e gene for conversion to suspension culture

Introduction: Inactivated influenza vaccines are traditionally produced in chicken embryonated eggs but its limitations in producing the required doses in pandemic outbreaks quickly enough has made searching for alternative modes of production necessary. The use of cell culture-based vaccine production is one way of overcoming the limitations of the egg-based method and securing a more rapid re...

[ 5 ] - Polyclonal Antibody against Recombinant Nucleoprotein of the Influenza A Virus (H1N1); Production and Purification

Background and Aims: Influenza is an acute respiratory illness that is caused by a virus belonging to Orthomyxoviridae family. This virus spreads rapidly every year in cold season and leads to morbidities and mortalities especially in adults and children, which causes billions of dollars of economic losses. Accordingly, development of a rapid, sensitive and inexpensive laboratory diagnosis base...

[ 6 ] - تخلیص پروتیین نوترکیب هماگلوتینین (HA1) ویروس آنفلوانزا سویه (A(H1N1 و تولید آنتی‌بادی پلی‌کلونال علیه آن

Background: Each year, Human influenza A (H1N1) virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, the rapid, sensitive and cost-effective laboratory diagnosis based on viral antigen detection is important. Moreover, the generation of specific antibodies directed against Influenza antigens is essential to the success of both basic and applied re...

[ 7 ] - تولید آنتی‌بادی پلی‌کلونال علیه ناحیه حفاظت‌شده هماگلوتینین ویروس آنفلوآنزا (A/H1N1/2009) سویه تهران: گزارش کوتاه

Background: The influenza virus is one of the most important factors for higher morbidity and mortality in the world. Recently, researchers have been focused on influenza conserved antigenic proteins such as hemagglutinin stalk domain (HA2) for vaccine production and serological studies. The HA2 plays a major role in the fusion of the virus with host cells membrane. The immunity system enables ...
