Abstract: A method and kit of diagnosing endometriosis in a female patient suspected of having endometriosis. The method includes obtaining a sample from the patient. The sample is analyzed to detect the presence of a purified and isolated endometriotic haptoglobin designated ENDO-I and functional analogs thereof. A therapeutic for treating endometriosis by modulating the expression of a purified and isolated endometriotic haptoglobin designated ENDO-I and functional analogs thereof and a pharmaceutically acceptable carrier.

Abstract: A method and kit of diagnosing endometriosis in a female patient suspected of having endometriosis is disclosed. The method includes obtaining a sample from the patient. The sample is analyzed to detect the presence of ENDO -I glycoprotein or its mRNA in the sample compared to non-endometriosis controls who do not express ENDO-I. The protein is characterized by (i) a molecular weight of 40,000 to 55,000 as determined by two-dimensional SDS-PAGE polyacrylamide gel electrophoresis; (ii) having an isoelectric point of 4.0 to 5.5; and (iii) being synthesized and secreted specifically by stromal cells of endometriotic tissue origin; and (iv) in humans having a cDNA as set forth in SEQ ID No:1. The present invention further discloses a cDNA for human ENDO-I (SEQ ID No:1) and antibody directed against ENDO-I.

Abstract: An antibody to the purified and isolated glycoprotein and functional analogs thereof characterized by being progesterone induced and estradiol inhibited secretory glycoprotein specifically from stromal cells of endometrial origin. The protein has the molecular weight of 70,000 daltons as determined by two-dimensional SDS-PAGE polyacrylamide gel electrophoresis and has an isoelectric point of 5.7.
