Abstract: Disclosed herein are methods for analyzing one or more analytes of a cell by performing single-cell analysis. In one scenario, the one or more analytes are located on a surface of the cell. In one scenario, the one or more analytes are located internally within the cell. In one scenario, the one or more analytes include proteins located on a surface of the cell and located internally within the cell.

Abstract: The present invention is generally directed to a lysis buffer for extraction of DNA from plant material and improved methods for extraction of DNA from plant material utilizing the novel lysis buffer. Advantageously, the lysis buffer of the present invention is suitable for use in connection with simpler analysis methods, while still providing suitable DNA yields and purities for analysis.

Abstract: A unique valve assembly for simulated bed moving chromatography employs a combination of pressure compatible sealable materials that permit minimal frictional interaction between moving parts, ensures alignment of parts, and provides a method for conducting SMB countercurrent chromatography on a small scale, in which purity and separation efficiency are enhanced. Machine designs are disclosed which embody the SMB concepts. Finally, a quick disconnect connector and adaptor is provided for mounting chromatographic columns in an SMB device. Demonstration of this system in a fructose-glucose isomer separation with purity-recovery trade-off for this device is also presented.
