摘要： Disclosed are methods and devices for loading a liquid sample into an array substrate with a plurality of compartments, for example, a dPCR chip. The method uses a loading device having a single flat surface to efficiently load a liquid sample into a plurality of compartments in the array substrate.

摘要： A pancreatin preparation having reduced viral infectivity includes one or more pancreatin enzymes and peracetic acid (PAA). At least one pancreatin enzyme may be derived from an animal source such as a porcine pancreas gland. In a particular embodiment, the one or more pancreatin enzymes are selected from the group consisting of lipases, proteases, and amylases.

摘要： Provided is a fluorescence reader that uses two excitation channels and can read up to seven different fluorescent dyes in a single run. Each excitation channel has one light source and one single excitation filter and one dichroic mirror. One excitation channel is capable of exciting multiple fluorescent dyes and can be used to distinguish multiple dyes in combination with multiple emission filters. The excitation channels are driven by a motor that can automatically switch the two excitation channels for taking images of up to seven different fluorescent dyes. An algorithm to calibrate the crosstalk between different fluorescent dyes is also provided. Also provided is a method for analyzing digital PCR data using a ratio of two fluorescence emission readings.

摘要： Disclosed are methods for detecting DNA mutations of target genes in a DNA sample by combining single-molecule clonal amplification and mutant primer specific extension detection. In the method, thousands and millions of DNA molecules are locally amplified to form immobilized DNA clusters of identical sequences. Mutation specific primers are used to anneal to the mutant sequences in the DNA clusters and are extended by DNA polymerase to make labeled DNA strands. The labeled DNA clusters are detected to identify the DNA clusters of mutant sequences. This method enables detection of single mutation molecule and direct enumeration of mutation molecules in the sample. Once generated from a DNA sample, the immobilized DNA clusters can be reused many times for detection of different mutations or sequences of interest. Methods for determining differential gene expression and chromosome copy number variation are also disclosed.

摘要： The present invention provides compositions useful as prodrugs and methods for making the same. The compositions include a fusion protein having a first delivery domain and a second protein precursor domain linked together via a linker sequence. The delivery domain is a protein capable of facilitating entry to a target cells via the endocytotic pathway, such as transferrin. The protein precursor is a prohormone or a profactor, such as proinsulin. Methods of this invention include the steps of selecting a protein suitable as the delivery domain, constructing a vector to encode the fusion protein, and expressing the fusion protein in a suitable expression host. Also disclosed is a method for targeted-delivery of prodrugs to livers and a method of reducing hepatic glucose production.
