Low Applied Voltage Effects on Thaumatin Protein Crystallization

Effects of impurities on membrane-protein crystallization in different systems

When starting a protein-crystallization project, scientists are faced with several unknowns. Amongst them are these questions: (i) is the purity of the starting material sufficient? and (ii) which type of crystallization experiment is the most promising to conduct? The difficulty in purifying active membrane-protein samples for crystallization trials and the high costs associated with producing...

An active leakage-injection scheme applied to low-voltage SRAMs

An active leakage-injection scheme (ALIS) for lowvoltage (LV) high-density (HD) SRAMs is presented. By means of a feedback loop comprising a servo-amplifier and a commondrain MOSFET, a current matching the respective bit-line leakage is injected onto the line during precharge and sensing, preventing the respective capacitances from erroneous discharges. The technique is able to handle leakages ...

Protein crystallization

This essay is about the crystallization of proteins. Since the first published observation of crystallizing proteins about 160 years ago, protein crystal growth has developed into an extensive research field with many applications, for instance in the pharmaceutical industry. In this report, an overview of the unique physical-chemical characteristics of protein molecules, their properties in so...
