• We analyzed the nAb response to each of the 2 recombinant and parent viruses in infected mice and found that nAb kinetics were solely determined by the viral surface GP and not by the virus backbone. (jci.org)
  • I. The appeal was lodged by the applicant (hereinafter 'appellant') against the decision of the examining division to refuse European patent application 01303073.9 with the title 'A hepatitis B virus (subtype ayw) surface antigen variant' which was published as EP 1 142 906. (epo.org)

  • This paper reviews cell surface Ags expressed on mouse hemopoietic and nonhemopoietic cells. (jimmunol.org)
  • Molecules on the surface of hemopoietic cells play important roles in the development and function of these cells and have permitted us to understand the immune system in increasingly great depth. (jimmunol.org)
  • In recent years, it has become clear that there is a considerable amount of cross-talk between cells of the hemopoietic system and nonhemopoietic cells, with much of this interplay mediated by cell surface molecules. (jimmunol.org)
  • This review includes a discussion of cell surface Ags expressed on both hemopoietic and nonhemopoietic cells. (jimmunol.org)
  • Antigens on surfaces of cells, including infectious or foreign cells or viruses. (umassmed.edu)
  • AU antigen is defined by reactions of sera from patient AU with cell-surface antigens of cultured autologous melanoma cells (SK-MEL-28). (pnas.org)
  • Maximum yield of AU antigen from AU melanoma cells was obtained after very short (5-15 min) digestion times in contrast to the more prolonged proteolysis required for maximum HLA and beta 2m release. (pnas.org)
  • Apparent discontinuous transcription of Trypanosoma brucei variant surface antigen genes. (nih.gov)
  • The repeated mini-exon sequence that encodes the first 35 base pairs of all variant surface antigen mRNAs of Trypanosoma brucei directs the synthesis of a discrete 137-nucleotide transcript. (nih.gov)
  • It thus seems that variant surface antigen mRNAs are transcribed discontinuously, and we present two alternative models for how this might occur. (nih.gov)
  • 1. An isolated variant hepatitis B surface antigen comprising an amino acid sequence wherein mutations from hepatitis B wild type ayw2 strain appear as follows: at position 103 isoleucine is present instead of methionine, at position 118 lysine is present instead of threonine, at position 120 glutamine is present instead of proline, at position 170 serine is present instead of leucine, and at position 213 serine is present instead of leucine. (epo.org)
  • The amino acid sequence of the surface antigen of the newly identified HBV strain, called LBN, had five amino acid differences, i.e. at positions 103, 118, 120, 175 and 213, when compared to the known isolate ayw2, the sequence of which was known from GenBank Accession No. X02496. (epo.org)

  • After affinity chromatography on LcH-agarose, the specific activity of AU antigen was increased 50-fold. (pnas.org)
