objective: the aim of this study was to construct a pcdna3.1+ vector containing fmdv type o/irn/1/2007-vp1 gene, protein expression in bhkt7 cells and evaluation of immune response in balb/c mice. materials and methods: fmdv type o/irn/1/2007 was isolated from a cattle in ray in 2007 and serotyped. the purified vp1 gene was sub-cloned into the ptz57r/t vector and pcdna3.1+ expression vector. t...

abstract background and aims: influenza a(h5n1) viruses  circulating in animals might evolve and acquire the ability to spread from  human to human and thus start a pandemic. hemagglutinin (ha) has been shown to play a major role in binding of influenza virus to its target cell and the main neutralizing antibody responses elicit against this region. recent studies have shown that glycosylation ...

introduction: omp31 is animmunodominant and protective antigen conserved in brucella species and a good candidate for vaccine design. material & methods: the present study aimed at in silico design of the truncated omp31 (tomp31) using bioinformatic tools and to express the selected form in escherichia coli (e. coli) results and conclusion: various bioinformatically calculated scores for the mo...

Protein adsorption is essential for determining material biocompatibility and promoting adherent cell growth. In this study, we focused on the a-plane structure of hydroxyapatite (HAp). This closely resembles crystal plane where apatite exposed in long bones. We conducted protein experiments using HAp ceramics with a preferred orientation to a-planes (aHAp), employing bovine serum albumin (BSA)...

To evaluate potential differences in protein A among Staphylococcus aureus strains, lysostaphin-solubilized cell wall proteins from 12 serologically distinct strains were analyzed by 7.5% sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis (PAGE). Seven presumptive protein A variant identified in the 45- to 57-kilodalton range were then studied for qualitative binding affinities to ...

objective: breast cancer is one of the leading causes of death in women worldwide. conventional treatments use cytotoxic drugs which have high numbers of side effects. currently pharmacologists are searching for novel drugs with fewer side effects and maximum efficiency as breast cancer treatment. the aim of the current study is to clarify the cytotoxicity effect of the recombinant outer membra...
