Abstract: The present invention is directed to novel DNA-RNA hybrids comprising either a DNA sense strand and an RNA antisense strand, or an RNA sense strand and a DNA antisense strand. The compounds of the invention, and compositions and arrays comprising the same, may be used for a variety of purposes, including inhibiting gene expression, treating disease and infection, determining the function of genes, and identifying and validating novel drugs and their targets.

Abstract: The present invention provides business methods, systems, and computer programs for identifying, categorizing, and guiding the selection of biological assays and reagents, as well as producing and selling customized catalogs and kits of reagents that may be used in performing such assays. These business methods, systems, and computer programs may be directed to a variety of applications, including biological research, medical diagnostics and therapeutics, detection or identification of microorganisms, contaminants, or infectious agents, and measuring or monitoring gene expression.
