Patent CA-2369923-A1 (CA)
Title: Detection de cancer et de grossesse anormale au moyen d'anticorps monoclonaux specifiques pour des isoformes de la hcg
Inventor: KRICHEVSKY ALEXANDER
IPC: C07K16/26
Filed: 2000-04-12
Abstract: La gonadotrophine chorionique humaine (hCG) existe dans le sang et l'urine en tant que variété d'isoformes. L'une d'elles, qui contient des clivages de liaisons peptidiques à l'intérieur de sa sous unité bêta, est désignée hCG coupée (hCGn). Cette isoforme de la hCGn est plus courante dans l'urine des patients présentant certaines malignités et éventuellement dans d'autres maladies de grossesse. L'invention porte sur deux anticorps monoclonaux à une isoforme de la hCGn isolée chez un patient choriocarcinome. Deux analyses immunométriques sur site ont été élaborées à l'aide de ces anticorps, désignés B151 et B152. Le premier présente une bonne spécificité pour hCGn indépendante de la source de la hCGn, forme évacuée par des patients choriocarcinomes, ou la forme de la hCGn provenant de grossesses normales. L'autre anticorps, B152, est exceptionnellement sensible aux fractions glucidiques de hCG choriocarcinome, coupée ou non, étant donné que sa reconnaissance de ligand est fonction des différences glucidiques plutôt que des différences de liaisons peptidiques. Ces deux analyses immunométriques apportent de nouveaux outils de diagnostic fondés sur le mesurage direct de ces isoformes de la hCG.
