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:
Una composicion que comprende: a) una primera polimerasa de acido nucleico; b) un primer mecanismo de arranque en caliente que comprende anticuerpos o combinaciones de anticuerpos que se unen a la primera polimerasa de acido nucleico; y c) un segundo mecanismo de arranque en caliente que comprende un agente que media una modificacion quimica reversible de la primera polimerasa, o un oligonucleotido o un ligando dependiente de la temperatura que se une a la primera polimerasa; en donde el primer mecanismo de arranque en caliente y el segundo mecanismo de arranque en caliente, juntos, son capaces de inhibir sustancialmente la actividad de la primera polimerasa a una primera temperatura, pero no a una segunda temperatura mas alta.
