摘要： The present invention discloses a corrugated settling cup and a multi-cup uniform flux gas anchor, which belong to oilfield gas-liquid separation devices. The external profile of the cup body of the corrugated settling cup rises in a corrugated shape along an axial direction of the corrugated settling cup, which facilitates rapid aggregation and rise of gas. The multi-cup uniform flux gas anchor is comprised of a plurality of the corrugated settling cups, and further includes a central pipe, a plurality of settling cup protectors and a well-flushing valve, wherein the plurality of settling cup protectors are slipped onto the central pipe in clearance fit and the plurality of the corrugated settling cups are slipped onto the central pipe in clearance fit between every two settling cup protectors, a plurality of liquid inlet holes are located evenly on the central pipe at a position close to an inner bottom of each corrugated settling cup, and a lower portion of the central pipe is connected to the well-flushing valve. With the plurality of the corrugated settling cups, the gas anchor divides a gas-liquid mixture into a number of portions, and the external profile rising in a corrugated shape allows the separated gas to rapidly aggregate and rise up, thereby achieving the object of performing effective gas-liquid separation, increasing pump efficiency and oil production, saving energy and reducing consumption.

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.
