摘要:
The present invention provides compositions and methods useful for diagnosing, treating, and preventing cancer, particularly ovarian cancer and uterine cancer, based on the discovery that the oocyte specific protein, SAS1R (Sperm Acrosomal SLL-P1 Receptor), which is a sperm protein receptor, is also expressed in various cancers, including ovarian cancer and uterine cancer. Six SAS1R variants have been previously identified, and they are encompassed by the invention. The present invention further provides antibodies useful for targeting SAS1R expressing cells and for killing such cells.
摘要:
The monoclonal antibody S19, expressed by Deposit HB12144, ATCC, effectively agglutinates a sperm surface glycoprotein, SAGA-1 protein. The mAB finds utility as a binding agent in a spermicide, showing a high degree of effectiveness in binding potential sperm. The protein bound, identified as SAGA-1, is the immunogen in a contraceptive vaccine, as well as the standard for determining antibody titer upon vaccination. The monoclonal antibody can also be used as a diagnostic to determine the presence, and amount, of sperm in a variety of samples.
摘要:
A coupled pair of fiber optic fibers are used an immunoassay device. The fibers are first coupled and then drawn down to a single mode diameter. The coupler senses output ratio change due to chemical, biochemical, bioaffinity, immunogenic-type interactions and other molecular activity occuring within the evanescent field. The fusion joint of the coupler is coated with a first immunoassay component, and then surrounded with a second immunoassay component.
摘要:
The present invention relates to novel egg membrane protein receptors and to methods of inhibiting the interaction of sperm proteins with egg proteins. The invention further relates to methods of preventing and inhibiting sperm-egg binding, sperm-egg fusion, and fertilization. The invention further relates to the egg membrane proteins MET and ZEP.
摘要:
The present invention relates to sperm specific surface proteins, nucleic acid sequences encoding those proteins and antibodies raised against those proteins. Compositions comprising the sperm specific proteins or inhibitors of said proteins can be used in contraceptive applications.
摘要:
The present invention relates to proteins that are expressed in oocytes, nucleic acid sequences encoding those proteins and antibodies generated against those proteins. Composition and methods are provided for using the disclosed oocyte proteins as targets for contraceptive drugs.
摘要:
The present invention relates to a family of testis specific kinases (the tssk family), nucleic acid sequences encoding those kinases and antibodies against the kinases. The invention is further directed to the use of those kinases as targets for isolating specific inhibitors or antagonists of tssk kinase activity. Such inhibitors are anticipated to have use as contraceptive agents.
摘要:
The present invention relates to compositions and methods for screening compounds that modulate meiotic progression. In particular, it relates to compositions comprising nucleotides from the mouse 5′ regulatory region, and transcriptionally active fragments thereof, that control the expression of a testis-enriched protein, SP-10. Specifically provided are expression vectors, host cells, and transgenic animals. The SP-10 promoter controls the expression of a heterologous gene, e.g., green fluorescent protein. The invention relates to methods for using the vectors, cells, and animals for screening candidate molecules for agonists and antagonists of sperm development and fertilization. Methods for using molecules and compounds identified by the screening assays for therapeutic treatments are provided.
摘要:
A substantially purified intra-acrosomal primate sperm antigen useful in a contraceptive vaccine is disclosed herein. The antigen remains associated with primate sperm after the acrosome reaction. In particular, it remains associated with the inner and outer acrosomal membranes. Modified antigens and fragments thereof prepared by protein modification techniques are also disclosed as well as methods for purifying and using the antigens. Also disclosed are monoclonal and polyclonal antibodies to the antigen and methods of making and using such antibodies. Methods of use include purification of the antigen or use in various diagnostic techniques. Also disclosed are cDNA, expression vectors, and transformed microorganisms that produce the antigen.
摘要:
A kit and method for detecting sperm production in a human male individual includes the provision of one or more antibodies for sperm tissue-specific protein antigen, such as SP-10, which can be combined with a sample suspected of containing sperm to permit the antibody and the antigen to bind. The binding event is determined directly or indirectly, which is indicative of the presence of sperm in the sample. The frequency of binding can also be determined by calibrating the means used to determine the binding event, so as to indicate sperm production at or above a given concentration. A variety of applications for the kit and method are described.
