    摘要： The present invention provides a process for determining the quantitative and qualitative profile of the repertoire of a given type of an immunoglobulin (Ig) heavy chain expressed by a B lymphocyte population present in a tissue sample, and kits and uses thereof. It also provides a set of VH forward primers associated with a CH reverse primer, which are respectively capable of specifically hybridizing in stringent conditions with the nucleic acids encoding the variable segments of Ig heavy chains and with the constant segment of a given type of Ig heavy chain, such as preferably an IgM, IgG, IgE or IgA heavy chain. Methods for the in vitro diagnosis of a condition associated with an abnormal expression of the repertoire of a given type of Ig heavy chain, and for the in vitro follow-up of a treatment of such a condition, are also included herein.

    摘要： The present invention relates to a process for determining the quantity of a DNA fragment of interest in a sample wherein: 1) a standard DNA fragment can be amplified with the same oligonucleotide primers is added to the sample to be analyzed containing the DNA fragment of interest, the standard DNA fragment and the fragment of interest differing in sequence and/or in size by not more than 10%, 2) the DNA fragment of interest and the standard fragment are coamplified with the same primers, preferably to saturation of the amplification of the DNA fragment of interest, 3) one or more labeled oligonucleotide primer(s), specific for the DNA fragment of interest and the standard fragment and different from the primers of step 2), is/are added to the reaction medium obtained in step 2), so that, after denaturation of the DNA, said primer(s) hybridize(s) with said fragments at a suitable site in order that an elongation with the DNA polymerase generates labeled DNA fragments of different sizes and/or sequences or with different labels according to whether they originate from the DNA fragment of interest or the standard fragment, respectively, and then 4) the initial quantity of DNA fragment of interest is determined as being the product of the initial quantity of standard DNA fragment and the ratio of the quantity of amplified DNA fragment of interest to the quantity of amplified standard DNA fragment.

    摘要： The present invention provides a process for determining the quantitative and qualitative profile of the repertoire of a given type of an immunoglobulin (Ig) heavy chain expressed by a lymphocyte B population present in a tissue sample, and kits and uses thereof. It also provides a set of VII forward primers associated with a CII reverse primer, which are respectively capable of specifically hybridizing in stringent conditions with the nucleic acids encoding the variable segments of Ig heavy chains and with the constant segment of a given type of Ig heavy chain, such as preferably IgM, IgG, IgE or IgA heavy chain. Methods for the in vitrodiagnosis of a condition associated with an abnormal expression of the repertoire of a given type of Ig heavy chain, and for the in vitro follow-up of a treatment of such a condition, are also comprised herein.

    摘要： An altered MHC class I determinant comprises .alpha..sub.1, .alpha..sub.2, .alpha..sub.3, .beta..sub.2 -microglobulin (.beta..sub.2 m) polypeptide domains encoded by a mammalian MHC class I locus in which the .alpha..sub.3 domain is covalently linked to the .beta..sub.2 M domain. An altered MHC class II determinant comprises .alpha..sub.1, .alpha..sub.2, .beta..sub.1, and .beta..sub.2 polypeptide domains encoded by a mammalian MHC class II locus, in which the domains are covalently linked to form a polypeptide comprising the .beta..sub.2 -.alpha..sub.2 -.alpha..sub.1 -.beta..sub.1 domains in sequence. The altered MHC class I and class II determinants can be associated with an antigen to elicit an immune response. The invention can be used in the immunization or treatment of diseases such as AIDS, multiple sclerosis, lupus erythematosus, toxic shock or snake bite.
