Abstract: The present invention provides methods for detecting biomarkers based on Abscription®, abortive transcription technology. Particularly, the present invention provides bisulfate free methods for detecting methylation of CpG islands from small samples of DNA. The methods are suitable for multiplexing and can be used to analyze multiple CpG islands from a single sample in a short time.
Abstract: The present invention provides a simple and sensitive technology for the detection of CpG methylation in DNA without chemical modification of sample DNA by bisulfite treatment or PCR amplification. Signal generation is based on an Abscription (Abortive Transcription) technology in which DNA signal generators called Abortive Promoter Cassettes (APCs) are bound to target mCpG sites via mCpG target specific probes based on methyl binding polypeptides or methyl binding domains thereof. RNA polymerase produces uniform, short RNA molecules from synthetic promoters in APCs as signals of the presence of methylated CpGs. Detection of CpG methylation and hypermethylation of DNA targets such as CpG islands provides a convenient means for detecting and monitoring cancer in a subject.
Abstract: The present invention provides electrically and thermally conductive compositions for forming interconnections between electronic elements. Invention compositions comprise three or more metal or metal alloy particle types and an organic vehicle comprising a flux that is application specific. The first particle type includes a reactive high melting point metal that reacts with a reactive low melting point metal(s) in the other particles to form intermetallic species. The reactive low melting point metal(s) of the invention are provided in two distinct particle forms. The first reactive low melting point metal particle includes a carrier that facilitates the reaction with the reactive high melting point metal. The second reactive low melting point metal particle acts primarily as a source of the reactive low melting point metal.
