For accurate protein quantification when using quantitative western blot analysis with chemiluminescence reagents, standard curves are needed because of the narrow quantifiable ranges. However, they are often difficult to obtain because authentic proteins are not always available. Here we present our original and convenient method using a sample mixture as a scale to create standard curves. Thi...
Isolated islands provide valuable opportunities to study the persistence of viruses in wildlife populations, including population size thresholds such as the critical community size. The straw-coloured fruit bat, Eidolon helvum, has been identified as a reservoir for henipaviruses (serological evidence) and Lagos bat virus (LBV; virus isolation and serological evidence) in continental Africa. H...
Abstract Background and objectives: Human T-Lymphocyte Virus-1 (HTLV- 1) is known as the etiologic factor of acute T-Lymphocytic Leukemia (ATL) and tropical spastic paralysis. (TSP). Endemic factors causing infection with Human T Lymphocyte Virus-1 (HTLV-1) is based on environmental, socio-economical and health behaviors of the individuals. This virus is well distributed in families with involv...
Blot overlay is a useful method for studying protein-protein interactions. This technique involves fractionating proteins on SDS-PAGE, blotting to nitrocellulose or PVDF membrane, and then incubating with a probe of interest. The probe is typically a protein that is radiolabeled, biotinylated, or simply visualized with a specific antibody. When the probe is visualized via antibody detection, th...
tissue factor ، فاکتور iii انعقادی یا cd142 یک گلیکوپروتئین غشائی است که با فاکتورvii انعقادی متصل شده و باعث آغاز آبشار انعقادی می گردد. استفاده از این فاکتور به عنوان معرف در تست انعقادی خون pt (prothrombin time) یکی از رایج ترین کاربردهای آن است. آزمایش pt یک تست غربالگری برای تشخیص نقص در فاکتورهای انعقادی و همچنین بررسی چگونگی درمان با داروهای ضدانعقاد خون نظیر وارفارین به شمار می رود. در...
The line blot, a new immunoassay in which antigens are placed on nitrocellulose as narrow lines, was evaluated for its sensitivity and specificity relative to the microimmunofluorescence assay for the diagnosis of Mediterranean spotted fever (MSF). The line blot assay was only slightly less sensitive and less specific than the microimmunofluorescence assay for detection of immunoglobulin M (IgM...
background : toxoplasma gondii is an obligate intracellular protozoan parasite, capable of infecting all species of mammals including man. congenital toxoplasmosis is more important during pregnancy for the first time. in this study we expressed and purified p43 toxoplasma gondii tachyzoite and bradyzoite specific surface antigen. methods : the recombinant pgemex-1 contained toxoplasma p43 codi...
Umbelliprenin is a prenylated compound, which belongs to the class of sesquiterpene coumarins. It is extracted from dried roots of Ferula szwitsiana collected from the mountains of Golestan forest (Golestan Province, north of Iran). Induction of apoptosis in Jurkat T-CLL cells has been previously shown. In this study, effect of umbelliprenin on proapoptotic caspases (caspase-8 and -9) and antia...
