Abstract: Methods for quantifying GDF-9-BMP-15 heterodimers and GDF-9 and BMP-15 homodimers using antibodies directed to epitopes in GDF-9 and BMP-15 in a sandwich ELISA are provided. Also provided are kits for quantifying the heterodimers.

Abstract: Disclosed are compositions and methods for detecting and quantifying human anti-Müllerian hormone (AMH) in biological samples. In particular, the invention provides novel methods of measuring different forms of AMH in a biological sample, such as human plasma The anti-AMH antibody compositions disclosed herein enable reproducible measurement and quantitation of AMH, including dimeric forms of the AMH protein and fragments thereof. The antibody compositions disclosed herein find particular utility as diagnostic tools for single epitope sandwich-based AMH assays, which can be used to diagnose a variety of medical conditions.

Abstract: PAPP-A2 is used as a marker for monitoring, predicting and diagnosing preeclampsia in pregnant women. PAPP-A2 levels in pregnant women with preeclampsia are higher than PAPP-A2 levels in normal pregnant women. This is especially true of PAPP-A2 levels that are measured later on in the pregnancy. PAPP-A2 levels may be measured early in pregnancy in order to predict the likelihood of the patient having preeclampsia. Preeclampsia may also be diagnosed at later gestational ages when the levels of PAPP-A2 are more pronounced than normal PAPP-A2 levels at the same gestational age. The present invention relates to methods of assessing, predicting and diagnosing preeclampsia as well as a kit-of-parts for assessing, predicting and diagnosing preeclampsia.

Abstract: The present invention discloses compositions and methods to measure an amount of Anti-Mullerian Hormone (AMH) in a sample, including a mammalian sample such as a primate, rodent, equine, or bovine sample. The compositions and methods herein also provide antibodies that bind to epitopes on AMH that are stable to proteolysis of AMH.

Abstract: The present invention provides for the measurement of prostate specific antigen (PSA) from extracts of blood dried on a suitable solid support. PSA in solid support dried blood is stable for more than 100 days at room temperature. The procedure of the present invention can reliably distinguish normal from elevated levels of PSA and that facilitates screening and monitoring to detect disease in large scale mail-in programs to centralized laboratories.
