    Abstract: According to the present teachings, compositions, kits, and methods for protein melt analysis are provided that utilizing one or more fluorophore dyes. In some embodiments, a method comprises preparing a sample by mixing at least one protein with two or more dyes, and applying a controlled heating, while recording the fluorescence emission of the sample. The methods can be used, for example, for screening conditions for optimized protein stability, screening for ligands that bind and enhance protein stability (e.g., protein-protein interactions), screening for mutations for enhanced stability, screening crystallization conditions for protein stability, screening storage conditions for protein stability, and screening conditions in which a protein will be used (e.g., production conditions, treatment conditions, etc.) for protein stability.

    Abstract: Systems, primers, kits, and methods for detecting microsatellite instability in a biological sample are described. Signal data is received from a capillary electrophoresis genetic analysis instrument, wherein the signal data is measured from fluorescence of fragments comprising nucleic acid sequences amplified from the biological sample via polymerase chain reaction (PCR). The nucleic acid sequences correspond to a plurality of different microsatellite loci and are obtained using a plurality of PCR primers configured to flank a plurality of microsatellite loci of a biological sample. When the PCR primers and the biological sample are combined and subjected to PCR amplification, fluorescently labeled DNA fragments are generated comprising the plurality of microsatellite loci. Fluorescent data obtained from the plurality of fluorescently labelled microsatellite loci are used to classify microsatellite instability of the biological sample.
