摘要:
Methods for obtaining recombinantly produced, C-terminally truncated, E1 and E2 polypeptides from cell lysates are disclosed. The intracellularly expressed truncated molecules display improved biological properties as compared to their secreted counterparts.

An approach is provided for processing promotional information for facilitating a point-of-sales transaction via radio frequency (RF) memory tags. A platform causes, at least in part, a capture of promotional information from a radio frequency memory tag associated with a merchant. The tags are placed at locations including a point-of-sales terminal, store entrance or near a poster to facilitate customer access. The platform processes and/or facilitates a processing of the promotional information to present one or more offers at a device, and receives an input for selecting at least one of the one or more offers for redemption. In response, the platform causes, at least in part, a validation of the redemption of at least one of the one or more offers. The platform then causes, at least in part, a presentation of the validation at the device for a confirmation by the merchant.

The present invention relates to the efficient expression of HIV polypeptides in a variety of cell types, including, but not limited to, mammalian, insect, and plant cells. Synthetic expression cassettes encoding the HIV Gag-containing polypeptides are described, as are uses of the expression cassettes in applications including DNA immunization, generation of packaging cell lines, and production of Env-, tat- or Gag-containing proteins. The invention provides methods of producing Virus-Like Particles (VLPs), as well as, uses of the VLPs including, but not limited to, vehicles for the presentation of antigens and stimulation of immune response in subjects to whom the VLPs are administered.
摘要:
Cytomegalovirus (CMV) Intron A fragments for expressing gene products are disclosed. Also described are expression vectors including the fragments, as well as methods of using the same.
摘要:
Described herein is a method of eliciting antibodies and neutralizing of binding antibodies against a hepatitis C virus (HCV) E1E2 or E2 antigen using HCV E2 or HCV E1E2 polypeptides and/or HCV E2 or E1E2 polynucleotides. Elicitation of anti-E2 antibodies and anti-E2 NOB antibodies can be used, inter alia, to provide model systems to optimize anti-E2 antibody responses and/or anti-E2 NOB antibody responses to HCV and to provide prophylactic or therapeutic treatment against HCV infection.

摘要:
Polypeptides comprising a mutant non-structural Hepatitis C virus useful in diagnostic and/or immunogenic compositions are disclosed, in which the mutant is an N-terminal mutation that functionally disrupts the catalytic domain of NS3. Polynucleotides encoding these polypeptides, host cells transformed with polynucleotides and methods of using the polypeptides and polynucleotides are also disclosed.
摘要:
The invention provides a method of activating hepatitis C virus (HCV)-specific T cells, including CD4+ and CD8+ T cells. HCV-specific T cells are activated using fusion proteins comprising HCV NS3, NS4, NS5a, and NS5b polypeptides, polynucleotides encoding such fusion proteins, or polypeptide or polynucleotide compositions containing the individual components of these fusions. The method can be used in model systems to develop HCV-specific immunogenic compositions, as well as to immunize a mammal against HCV.
