Introduction biological specificity

FRET to occur, and thus no FI emission is observed. The specificity of this assay was also examined for mixed samples. The mixed lysozyme samples were prepared in fetal bovine serum (FBS), human saliva and human urine. It was found that FAM emission was still visible upon addition of each mixed sample, implying that this assay has a great potential for the detection of real biological samples. This study illuminates that introduction of specific aptamer/protein interaction as the recognition event, and utilization of FRET as the signal transduction channel, is an effective way to develop CPE-based protein sensors with good specificity. [Pg.442]

The objective here is to describe how the traditional field of physical chemistry applies to the study of biology, specifically to provide a broad and relatively nontechnical introduction for nonspecialists. However, a comprehensive description of the role of physical chemistry in biology is a mammoth task that... [Pg.1494]

The class of proton transfer (PT) reactions plays a major role in many biological processes, including various enzymatic reactions. This class of reactions will be served here as a general example and an introduction for more complicated reactions. As a specific demonstration let s consider a proton transfer between Cys 25 and His 159 in papain. This reaction can be formally described as... [Pg.140]

Currently, HPLC/fiuorescence is still the most common technique for the determination of residues of oxime carbamates. With the introduction of ESI and APCI MS interfaces, HPLC/MS analysis for oxime carbamates in various sample matrices has become widespread. However, for a rapid, sensitive, and specific analysis of biological and environmental samples, HPLC/MS/MS is preferred to HPLC/MS and HPLC/fiuorescence. With time, improved and affordable triple-quadrupole mass spectrometers will be available in more analytical laboratories. With stricter regulatory requirements, e.g., highly specific and conclusive methods with lower LOQ, HPLC/MS/MS will be a method of choice for oxime carbamates and their metabolites. [Pg.1161]
