Hepatitis B core antigen is one of the most promising protein carriers of foreign epitopes of various human and animal pathogens. Chimeric HBcAg particles can be used as effective artificial immunogenes. Unfortunately, not all chimeric proteins are able to be particulated. The dependence of correct or incorrect folding of chimeric proteins on physical and(More)
A synthetic T cell immunogen (TCI) has been designed as a candidate DNA-based vaccine against Human immunodeficiency virus (HIV)-1 using cytotoxic T lymphocytes (CD8(+) CTL) and T-helper lymphocytes (CD4(+) Th) epitopes retrieved from the Los Alamos HIV Molecular Immunology Database. The protein 392 amino acids in length contains about eighty CTL-epitopes,(More)
Single-spin asymmetries for semi-inclusive electroproduction of charged pions in deep-inelastic scattering of positrons are measured for the first time with transverse target polarization. The asymmetry depends on the azimuthal angles of both the pion (phi) and the target spin axis (phi(S)) about the virtual-photon direction and relative to the lepton(More)
The library of human scFv antibodies displayed on the surface of bacteriophages was panned against Vaccinia virus (VACV), strain Elstree. 75% binding with Vaccinia virus. 5 clones were characterized for their binding with VACV and their ability to neutralize VACV in plaque reduction neutralization test (PRNT). Antibodies from the clones were obtained as(More)
A global AIDS epidemics caused by human immunodeficiency virus type 1 (HIV-1), involving more than 2 million newly infected people annually, has existed for more than 25 years. The major obstacle in combating the global epidemic is rapid evolution of the virus by the selection of drug resistance mutations. Selection of drug-resistant HIV variants is so(More)
A combinatorial immune library of human single-chain antibodies (scAbs) was constructed using the genes coding for the variable domains of the heavy and light chains of human immunoglobulins. The genes were cloned from lymphocytes of four subjects vaccinated with the vaccinia virus (VACV). The library included 3 · 107 independent clones. After enrichment(More)
A phage peptide library was screened with virus-neutralizing monoclonal antibodies (MAb) 2F5 which recognize a conserved epitope of HIV-1 gp41. Phages that expose peptides specifically binding with MAb 2F5 were selected by ELISA. Amino acid sequence analysis revealed homology to region 662–671 of HIV-1 HB10 gp160 for most peptides. The major role in(More)
Earlier, we developed an expression vector allowing exposure of short peptides on the surface of bacteriophage M13. It was used to obtain a recombinant phage carrying an antigenic determinant of HIV1 p17 Gag protein. Immunoglobulin elicited by immunizing rabbits with the phage reacted with the 17-kDa core protein of the virus and with its polyprotein(More)
Constructing a vaccine against HIV-1, able to induce production of broadly neutralizing antibodies, is crucial. We report here the selection and characterization of RDWSFDRWSLSEFWL peptide mimotope that binds specifically to bNAbs 2F5. The peptide mimotope was selected from 15-mer phage-displayed peptide library by using Mab 2F5 as the selecting agent. The(More)
For detection of spring viremia of carp virus (SVCV) DNA probes have been constructed using the reverse transcription-polymerase chain reaction (RT-PCR) amplification technique and cDNA cloning in plasmid and phage vectors. The specific primers for amplification of SVCV M and G genes were chosen and synthesized. Studies were carried out to establish the(More)
