  • Methods and kits for detecting ITA in a biological sample
    Patent number: 7897362
    Abstract: Methods for detecting invasive trophoblast antigen (ITA) in biological samples comprise screening the samples for ITA using antibodies that bind to the ITA. The methods are useful to detect pregnancy, trophoblastic diseases, and Down's syndrome in fetuses of pregnant women. Some methods include screening the samples with a plurality of capture antibodies that specifically bind ITA. Chemiluminescent immunoassays are disclosed. The methods may be practiced with the diagnostic kits of the invention.
    Type: Grant

  • Methods for detecting pregnancy
    Patent number: 6627457
    Abstract: Methods for detecting pregnancy in a woman comprise screening a biological sample of the woman for pregnancy markers. The methods of the invention include chemiluminescent assays for the pregnancy markers. The methods of the invention also comprise utilizing at least two capture antibodies that specifically bind different epitopes of the pregnancy marker in one assay. The methods of the invention permit detection of pregnancy within about 7 days after ovulation or implantation.

  • Methods for detecting Down's syndrome
    Publication number: 20030027234
    Abstract: Methods for detecting Down's syndrome in a fetus of a pregnant woman include screening serum samples obtained from the pregnant woman for abnormal levels of invasive trophoblast antigen. In particular, serum levels of invasive trophoblast antigen are compared to a standard. The methods can also be practiced using at least one additional marker.
