Abstract: A bi-epitope compound of formula (I): in which (i) E1 and E2, which may be identical or different, each independently represent a peptide sequence comprising at least one epitope of an analyte, (ii) X and Y, which may be identical or different, each independently represent a linker arm, (iii) the carrier molecule is soluble, and (iv) Z represents an amino acid derivative that had a thiol function before the bonding thereof with the carrier molecule.

Abstract: A bi-epitope compound of formula I: in which: E1 and E2, identical or different, each separately represents a peptide sequence including at least one epitope of an analyte; X and Y, identical or different, each separately represents a linking arm, the carrier molecule is soluble and Z represents an amino acid derivative bearing a thiol function prior to the bonding of same with the carrier molecule. The compound may be contained in a composition, used as a control or standard in an immunoassay and associated method, and/or provided in a kit for implementing an immunoassay.

Abstract: An immunoassay composition includes at least (i) an amphipol and (ii) a (meth)acrylate monomer-based amphoteric copolymer, some of said monomers including a phosphorylcholine group. The composition is useful in particular as a stabilizer and/or blocking agent.

Abstract: A method for the in vitro diagnosis of colorectal cancer by determining the presence of the Ezrin tumor marker in a biological sample taken from a patient suspected of having colorectal cancer using at least one anti-Ezrin monoclonal antibody directed against an Ezrin epitope chosen from the epitopes of sequence SEQ ID No.1, SEQ ID No.2, SEQ ID No.3, SEQ ID No.4+SEQ ID No.5, SEQ ID No.6+SEQ ID No.7 and SEQ ID No.8. Said method can be used for early diagnosis, screening, therapeutic follow-up and prognosis, and also for relapse diagnosis in relation to colorectal cancer.

Abstract: Disclosed is a process for in vitro detection of an infection by a dengue virus in an individual, including the following steps: contacting a blood sample from the individual with a ligand specific to the NS1 protein of said dengue virus, to capture NS1 protein if it is present in the blood sample, said ligand being immobilized on a solid support; detecting the presence of NS1 protein via a mass spectrometry reading; and if NS1 protein is detected, concluding that the individual has been infected by dengue virus.

Abstract: A method for the in vitro diagnosis of colorectal cancer that comprises determining the presence of the protein disulfide isomerase tumor marker in a biological sample taken from a patient suspected of having colorectal cancer using at least one anti-PDI monoclonal antibody directed against a PDI epitope chosen from the epitopes of sequence SEQ ID No.1, SEQ ID No.2, with an aromatic amino acid which is close in the three-dimensional structure of PDI and SEQ ID No.3.

Abstract: The present invention relates to a method for the in vitro diagnosis of colorectal cancer by determining the presence of the Prodefensin-A6 tumor marker in a biological sample taken from a patient suspected of having colorectal cancer, it being possible for said method to be used both in early diagnosis, screening, therapeutic follow-up and prognosis, and in relapse diagnosis in relation to colorectal cancer.
