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.

摘要： The invention discloses a disposable array-type micro injection needle head which comprises a lower needle seat which is configured as a cylindrical column opening at one end and having a top cap at the other end and which is configured to be connected with an injection reservoir; an upper needle seat which is located above the top cap of the lower needle seat with a cavity formed between the upper needle seat and the top cap; a through-hole formed in the top cap which is configured for communicating the cylindrical column with the cavity, wherein a pipetting needle is mounted in the through-hole which has one end communicated with the cavity and the other end located in the cylindrical column and which is configured for extracting injection from the injection reservoir into the cavity; and at least two needle tubes mounted in the upper needle seat, each of which has one end comprising a needle tip for puncturing and for injecting the injection and the other end for mounting on the upper needle seat and for communicating with the cavity. The needle head can be used directly on existing insulin pen, or the cylindrical column can be provided inside it with an injection reservoir to form a disposable prefilled syringe. By using a plurality of thin, short needle tubes for injecting simultaneously, vertical hypodermic injection of medicines such as insulin can be preformed rapidly, leakproof, painlessly, safely and conveniently at various sites of a human body, without needing to pinch skin, while a potential trouble that the medicines be injected into muscles can be avoided. Patient adherence to the treatment regimen and the treatment effect are improved.
