The present invention relates to the typing of HLA alleles. The sequence of exon 2 and exon 3 of the alleles HLA-B*3913, HLA-B*1406, and HLA-B*51new and of exon 2 of the alleles HLA-DRB1*0820, HLA-DRB1*04new and HLA-DRB4*01new are disclosed. The present invention relates to methods for typing of said alleles. According to a preferred embodiment, said typing comprises the following steps: i) amplifying a relevant fragment of said alleles using at least one suitable pair of primers; ii) hybridizing the amplification product of step i) to at least one probe that specifically hybridizes to a target region comprising one or more polymorphic nucleotides in said relevant fragment; iii) determining from the result of step ii) the absence or presence of said alleles in the sample. The present invention further provides primers and probes to be used in said methods for typing. A diagnostic kit comprising said primers and probes is also part of the present invention.

Transfusion of contaminated blood has become the major route of transmission for Chagas' disease. Current screening tests are insensitive and yield conflicting results, while confirmatory assays do not exist. The present invention relates to antigens and their use for serological diagnosis of Chagas' disease. More specifically, the present invention concerns assays which are able to reliably and accurately detect the presence of antibodies to various specific antigens of Trypanosoma cruzi in a highly sensitive and specific manner.
摘要:
The present invention relates to a method for purifying recombinant HCV single or specific oligomeric envelope proteins selected from the group consisting of E1 and/or E1/E2 characterized in that upon lysing the transformed host cells to isolate the recombinantly expressed protein a disulphide bond cleavage or reduction step is carried out with a disulphide bond cleavage agent. The present invention also relates to a composition isolated by such a method. The present invention also relates to the diagnostic and therapeutic application of these compositions. Furthermore, the invention relates to the use of HCV E1 protein and peptides for prognosing and monitoring the clinical effectiveness and/or clinical outcome of HCV treatment.
摘要:
The present invention relates to a method of producing certain peptides containing methylated arginines that are followed by a glycine residue and that constitute immunogenic determinants of antibodies present in sera from patients with systemic lupus erythematosus, or Epstein-Barr virus and wherein the methylation is a prerequisite for reacting with said antibodies. The invention also relates to the use of said peptides for diagnosis and treatment of systemic lupus erythematosus and related diseases, and diseases in which Epstein-Barr virus has been implicated.
摘要:
The present invention relates to new nucleic acid sequences derived from the ITS (Internal Transcribed Spacer) region, between the 16S and 23S rRNA genes, to be used for the specific detection and/or identification of Serratia species, in particular of Serratia marcescens, Serratia ficaria and/or Serratia fonticola, in a biological sample. The present invention relates also to a method for the specific detection and/or identification of Serratia species, in particular Serratia marcescens, Serratia ficaria and/or Serratia fonticola, using said new nucleic acid sequences derived from the ITS region. It relates also to nucleic acid primers to be used for the amplification of said spacer region of Serratia species in a sample.
摘要:
The invention relates to a process for genotyping any HCV isolate present in a biological sample, previously identified as being HCV positive, and for classifying said isolate according to the percentage of homology with other HCV isolates, comprising the steps of: contacting said sample in which the ribonucleotides or deoxyribonucleotides have been made accessible, if need be, under suitable denaturation, with at least one probe from about 10 to about 40 nucleotides, with said probe being liable to hybridize to a region being in the domain extending from nucleotide at position null291 to nucleotide at position null66 of the 5null untranslated region of one of the HCV isolates represented by their cDNA sequences, with said numbering of position beginning with the first ATG codon of the open reading frame encoding the HCV polyprotein, or with said probe being complementary to the above-defined probes, detecting the complexes possibly formed between said probe and the nucleotide sequence of the HCV isolate to be identified.
摘要:
The invention relates to immunogenic and vaccine compositions useful in prophylactic and therapeutic treatment of HCV infection. More specifically, said compositions comprise a HCV envelope peptide and a HCV non-structural peptide.
摘要:
The present invention relates more particularly to a monoclonal antibody which forms an immunological complex with a phosphorylated epitope of an antigen belonging to abnormally phosphorylated tau (PHF-tau) residing in the region spanning positions (143-254), and with said monoclonal antibody being characterized by the fact that it is capable of specifically detecting abnormally phosphorylated tau protein (PHF-tau) in cerebrospinal fluid (CSF).
