Abstract: Cette invention a trait à un procédé d'évaluation comparative de concentrations en séquences spécifiques nucléotidiques dans des échantillons provenant de diverses sources. Elle concerne, plus particulièrement, un procédé faisant intervenir des oligonucléotides liés de manière covalente à un support solide, des billes par exemple, afin d'isoler des séquences spécifiques nucléotidiques marquées dans des mélanges complexes. Les procédés de l'invention permettent d'effectuer des comparaisons quantitatives de la concentration en acide nucléique d'une séquence définie dans une pluralité d'échantillons différents d'acide nucléique, provenant, par exemple, de cellules ou de tissus différents ou de banques génétiques. Les acides nucléiques provenant des échantillons sont marqués de manière que les signaux puissent être différenciés et comparés après hybridation aux oligonucléotides se trouvant sur les billes. Il est possible, au titre de cette invention, de prélever les supports solides porteurs de l'acide nucléique hybride ainsi que d'éluer et d'analyser l'acide nucléique cible. Cette invention a trait, en outre, à un procédé permettant de marquer des clones individuels en provenance d'une banque génomique et ce, afin qu'ils puissent être identifiés uniquement et extraits par hybridation à des billes spécifiques.
Patent CA-2279134-A1 (CA)
Inventor: GUO ZHONGNU
IPC: C12N5/07
Filed: 1999-07-29
Abstract: The sialic acid component of a sialic acid unit-containing cell surface marker characteristic of cancerous mammalian cells, such as .alpha.2-8 polysialic acid, is modified, so that cells normally expressing such a marker express instead a modified sialic acid unit-containing cell surface marker which is strongly immunogenic. For example, the present invention enables, in a portion of patient cells which regularly express .alpha.2-8 polysialic acid (i.e. various types of cancer cells), the expression of a highly immunogenic surface antigen namely, modified .alpha.2-8 polysialic acid. The modification is suitably N-acylation of a precursor of the sialic acid, so that the N-acylated precursor becomes chemically incorporated in the polysialic acid during its intracellular biochemical synthesis.  Antibodies specific for the modified antigen, which can be induced using a conjugate of a suitable portion of the modified sialic acid unit-containing marker (such as .alpha.2-8 polysialic acid) and a protein, can then be used to eliminate cells which express .alpha.2-8 polysialic acid. Vaccines can be prepared utilizing conjugates of the modified sialic acid-containing marker, or utilizing antibodies produced in response to exposure of a suitable subject to the modified sialic acid-containing marker, for managing cancer conditions which involve cancer cells characterized, at least in part, by expression of modified sialic acid unit containing marker.
