  • Publication number: 20130116136
    Abstract: The current invention is concerned with a composition comprising at least one probe oligonucleotide each for the nucleotide sequences of the invention, said probe oligonucleotides specifically hybridizing to the sense strand or the antisense strand of said nucleotide sequences. Moreover, the present invention relates to a method for the identification of low-risk HPV types in a sample comprising the steps of a) contacting a sample with an amplification composition allowing amplification of at least one region of the HPV genome specifically hybridizing to at least one of the probe oligonucleotides of the current invention under conditions which allow for the amplification of polynucleotides and b) identifying low-risk HPV genotypes in said sample based on the amplified polynucleotides obtained in step a) by hybridizing the amplified polynucleotides with at least one labelled probe oligonucleotide of the current invention while said amplified polynucleotides are present in the same reaction container.

  • Publication number: 20130029319
    Abstract: The present invention relates to the field of diagnostic measures. In particular, the present invention relates to a method for predicting the risk of mortality in a subject suffering from low viral load HPV (human papillomavirus) positive oropharyngeal squamous cell cancer. The method is based on the determination of the amount of an E6* gene product and the amount an E1?E4 gene product of HPV in a sample from said subject. Moreover, the method is based on determining the presence of absence of an E1C gene product of HPV. The present invention further relates to a method for predicting the risk of mortality in a subject suffering from HPV (human papillomavirus) positive oropharyngeal squamous cell cancer based on the determination of copy number of HPV per cancer cell.

  • Publication number: 20050042714
    Abstract: The present invention relates to glycoconjugates containing a sialic acid derivate of general formula (I) and wherein the sialic acid derivate of general formula (I) is conjugated to a mono-, di- or oligosaccharide with up to 40 glycosidically linked, optionally branched sugar residues representing furanose and/or pyranose rings, which are linked N- or O-glycosidically to the polypeptide.

  • Publication number: 20030044870
    Abstract: The present invention relates to a generic capture ELISA for the detection and measurement of antibodies in biological fluids such as serum. This newly developed enzyme-linked immunosorbent assay (ELISA) system uses a first binding partner of a binding pair, preferably glutathione, crosslinked to casein as capture protein to bind recombinant protein antigens fused to a second binding partner of said binding pair, preferably N-terminal glutathione S-transferase (GST). The method not only allows the specific and efficient detection of antibodies in biological samples but, in addition, simple and efficient immobilization and one-step purificaton of overexpressed recombinant antigens even from crude lysates on ELISA plates coated with the first binding partner/casein. Several antigens can be tested in parallel under the same conditions without the need to biochemically purify or renature the proteins.
