Methods for predicting preganancy outcome in a subject by hCG assay
View Patent ↗The present invention provides a method of predicting pregnancy outcome in a subject by determining the amount of an early pregnancy associated molecular isoform of hCG in a sample. The present invention further provides a method for determining the amount of early pregnancy associated molecular isoforms of human chorionic gonadotropin (hCG) in a sample. The present invention also provides a diagnostic kit for determining the amount of early pregnancy associated hCG in a sample. The present invention additionally provides an antibody which specifically binds to an early pregnancy associated molecular isoform of human chorionic gonadotropin. Finally, the present invention provides methods for detecting trophoblast or non-trophoblast malignancy in a sample.
1. A method for determining the amount of an early pregnancy associated molecular isoform of hCG in a sample comprising: (a) contacting the sample with an antibody which specifically binds to a carbohydrate moiety of an early pregnancy associated molecular isoform of hCG under conditions permitting formation of a complex between the antibody and the early pregnancy associated molecular isoform of hCG; and (b) determining the amount of complex formed, thereby determining the amount of early pregnancy associated molecular isoform of hCG in the sample.
2. The method of claim 1 , wherein the antibody is produced by the hybridoma cell line accorded ATCC Accession No. HB-12467.
3. The method of claim 1 , wherein the antibody is B152.
