Abstract: The present invention provides probes, kits and methods for specifically binding mRNA of target cells, e.g., fetal cells, that allows visualization of the target cells, under conditions that allows a second probe to specifically bind the target cell's chromosomal DNA.

Abstract: The present invention discloses methods of determining the RhD genotype of subject. In particular, the invention provides a non-invasive method of determining fetal RhD genotype from a maternal biological sample containing fetal cells. The invention also provides novel probes and primers useful in the described methods. Kits and mixtures comprising the novel probes and primers are also disclosed.

Abstract: The present invention provides methods for isolating cell free nucleic acid, e.g., apoptotic or fetal nucleic acids and methods of detecting neoplastic cells or identifying the genetic composition of a fetus. The invention also provides magnetic particles comprising an anti-DNA antibody, and kits comprising the magnetic particles.

Abstract: The present invention provides compositions comprising a solution of a compound useful for lysing biological cells and methods for using the compositions to lyse biological cells and to isolate nucleic acid.

Abstract: The present invention provides methods and kits useful for genetic testing or screening of fetuses using nucleic acid samples isolated from cervical mucus samples of fetus hosts.

Abstract: A method and kit are provided for visualization of a latent pattern of molecular structures on a substrate surface. The method is comprised of exposing the substrate to a solution of nano-particles or to a powder of nano-particles. A detectable change is brought about as a result of non-specific binding nano-particles to the chemical groups on the substrate surface carrying the target molecular structures. The invention also provides compositions and kit for practicing the method. Further, the invention provides methods of capturing image of the substrate surface for visualization and quantitation of the molecular structures.
