    摘要: Methods, compositions, systems, apparatuses and kits comprising modified proteins, particularly modified nucleic acid-binding proteins with altered buffering properties are provided. For example, in some embodiments, methods of forming modified proteins including one or more amino acid modifications to achieve desired pKa values are described. Furthermore, the invention provides methods for using such modified proteins in ion-producing reactions, such as ion-based nucleic acid sequencing reactions.

    摘要: Methods and apparatus relating to very large scale FET arrays for analyte measurements. ChemFET (e.g., ISFET) arrays may be fabricated using conventional CMOS processing techniques based on improved FET pixel and array designs that increase measurement sensitivity and accuracy, and at the same time facilitate significantly small pixel sizes and dense arrays. Improved array control techniques provide for rapid data acquisition from large and dense arrays. Such arrays may be employed to detect a presence and/or concentration changes of various analyte types in a wide variety of chemical and/or biological processes. In one example, chemFET arrays facilitate DNA sequencing techniques based on monitoring changes in hydrogen ion concentration (pH), changes in other analyte concentration, and/or binding events associated with chemical processes relating to DNA synthesis.
