Background: Cultivated mammalian cells, because of their capacity for proper protein folding, assembly and post–translational modification, have become the dominant system for production of recombinant proteins in clinical application. Therefore, the quality and efficacy of protein can be superior when expressed in mammalian cells compared to other hosts such as bacteria. Gene reporte...
this study investigated how group formation method, namely student-selected vs. teacher-assigned, influences the results of the community model of teaching creative writing; i.e., group dynamics and group outcome (the quality of performance). the study adopted an experimental comparison group and microgenetic research design to observe the change process over a relatively short period of time. ...
A modified phage-enzyme link immunosorbent assay (phage-ELISA) and a phage dot-blot assay specific for hepatitis B surface antigen (HBsAg) and its antibody were developed by using phage display technology. The phageELISA and phage dot-blot assays enabled to detect HBsAg and anti-HBsAg in human sera, and compatible to commercial detection kit. The fusion phages were immobilized onto microtiter p...
Foot-and-mouth disease (FMD) is a highly contagious animal that causes devastating economic losses. The trade of live animals and derived products only possible if the exporting country free from disease, according to World Organization for Animal Health (WOAH) code FMD. One most important ways prove disease-free measure levels non-structural protein antibodies (NPS) FMD virus in target populat...
We assessed the performance of an enzyme-linked immunosorbent assay (ELISA) with the Trypanosoma cruzi epimastigote ribosomal fraction (Tulahuen and Y strains) in order to improve the diagnostic specificity of the test. A total of 100 serum samples from patients with chronic Chagas' disease from Brazil and Argentina were studied. Sera from 116 patients, without Chagas' disease, including 10 wit...
Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...
BACKGROUND The present recommendation for the serologic diagnosis of Lyme disease is a 2-tier process in which a serum sample with a positive or equivocal result by an enzyme-linked immunosorbent assay (ELISA) or immunofluorescent assay is then followed by supplemental testing by Western blot. Our laboratory has developed recombinant chimeric proteins composed of key Borrelia epitopes. These no...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
BACKGROUND Detection of Plasmodium vivax specific antibodies with serological tests could be a valuable tool for epidemiological researches. Whereas P. vivax cannot be simply obtained in vitro, serological tests using total or semi-purified antigens are infrequently used. Given this restriction, the present study investigated whether recombinant P. vivax merozoite surface protein 1 (PvMSP-1 42 ...
Abstract Background and objectives: HTLV-1 virus belongs to the retrovirus and infection with this virus mostly is seen among people having more than one time blood transfusion. Because of requiring repeated blood transfusions, thalassemic patients are considered to be high risk subjects in this regard. Thus, this study was carried out to indicate the frequency of HTLV-1 infection among the tha...
