Abstract: The present invention provides an array of compositions useful for effecting and/or exhibiting changes in biological functioning and processing within cells and in biological systems containing such cells. In effect, these compositions combine chemical modifications and/or ligand additions with biological functions. The chemical modifications and/or ligand additions provide additional characteristics to the compositions without interfering substantially with their biological function. Such additional characteristics include nuclease resistance, targeting specific cells or specific cell receptors localizing to specific sites within cells and augmenting interactions between the compositions and target cells of interest as well as decreasing such interactions when desired. Also provided by the present invention are processes and kits.

Abstract: Procedures and compositions for forming and stabilizing non stable branch migrated oligo- and polydeoxynucleotides utilizing a displacer which is either single stranded or partially double stranded and hybridized to a linker strand. The displacer may contain one or more modified nucleotides.

Abstract: This invention provides methods for the detection of a target genetic material having a desired base sequence or gene. Also disclosed are methods for the detection of mutations. Also provided are components for use in such methods.

Abstract: Double hybrid or multihybrid probes and compositions are usefully combined with capture assay and immobilization to provide for detection processes in which target polynucleotides can be detected or the presence or absence of genetic mutations or defects in genetic material can be determined. The capture assay involves capturing a hybrid structure, e.g., single hybrid, double hybrid or multihybrid, or capturing a complex formed by reacting a hybrid structure with a complex forming moiety, e.g., protein, such as a binding protein including an antibody. Immobilization can also be employed prior to hybridization or complexation in which instance a polynucleotide probe can be fixed to a matrix or solid support, e.g., natural or synthetic. Capture and immobilization can be carried out using direct and indirect binding and attachment techniques. Targets can be detected directly or indirectly by using a signal generating moiety and labels.

Abstract: This invention provides inter alia an in vitro process for producing multiple specific nucleic acid copies in which the copies are produced under isostatic conditions, e.g., temperature, buffer and ionic strength, and independently of any requirement for introducing an intermediate structure for producing the copies. In other aspects, the invention provides in vitro processes for producing multiple specific nucleic acid copies in which the products are substantially free of any primer-coded sequences, such sequences having been substantially or all removed from the product to regenerate a primer binding site, thereby allowing new priming events to occur and multiple nucleic acid copies to be produced. This invention further provides a promoter-independent non-naturally occurring nucleic acid construct that produces a nucleic acid copy or copies without using or relying on any gene product that may be coded by the nucleic acid construct.

Abstract: This invention provides methods and compositions for the detection of a target genetic material having a desired base sequence or gene. Also disclosed are methods and compositions for the detection of mutants. The methods and compositions are based in part upon techniques which utilize two labeled single-stranded polynucleotide segments which are complementary to different portions of the genetic material. The methods and compositions of this invention result in the formation of a double hybrid and/or multihybrid, and can furthermore be employed in an attached system, i.e., a matrix-bound entity capable of binding to a polynucleotide probe entity.

Abstract: The present invention relates to a wide range of genetic analyses using the technique of nucleic acid hybridization. These genetic analyses include, for example, the diagnosis of infections by foreign microbes and the detection of specific genetic traits and abnormalities. More specifically, the present invention is related to the detection of the presence of a polynucleotide sequence of interest.
