    Development of Multiplex SNP Genotyping Method Using Ligation-based Reaction Coupled with High Resolution CE-SSCP

    No full text
    DoctorSingle nucleotide polymorphisms (SNPs) are defined as DNA sequence variation containing single base substitution, small deletions or insertions that are present in at least 1% of population. SNPs have been found to be associated with disease susceptibility. Notably, SNPs account for about 90% of all human genetic variations. Numerous researchers have devoted years to developing SNP genotyping methods as validation tool for disease-related SNP marker candidates and diagnostic method using them. For the development of clinically useful genotyping method for SNP markers, accuracy, simplicity, sensitivity, and cost-effectiveness are the most important criteria. Among the developed many detection methods to date, Sequencing-based methods and real-time PCR based methods are widely used for SNP genotyping. However, both have low multiplexing power. As alternatives, single-base extension based methods have been developed for multiplex analysis, but they suffer from complicated procedures or error-prone detection methods. Although ligation dependent methods are considered the simplest multiplex genotyping method for SNPs, multiplex assays using this method are limited by the detection method and mismatched hybridization cannot be often discriminated at the SNP sites. In addition, sensitivity is not guaranteed by the ligation reaction alone. Although capillary electrophoresis (CE) is an attractive alternative to error-prone hybridization-based detection, the multiplex assay process is complicated because of the size-based DNA separation principle. In this dissertation, a novel SNP detection method by using improved ligation-based reaction coupled with high resolution CE-based single strand conformation polymorphism (SSCP) are developed as an accurate, sensitive and simple multiplex genotyping technology. To improve ligation reaction method, here we introduced various strategies to enhance accuracy, multiplex capacity, sensitivity, and precision of the analysis for a number of SNPs spread in the specific genes. First, to improve the specificity of the ligation reaction for discrimination of mismatched hybridization at SNP sites, strategies using optimization of ligation reaction condition and thermostable ligase which have activity near the melting temperature of probes. As a result, mismatched hybridizations were efficiently discriminated and specific SNP allele targets were successfully detected by optimizing ligation time and ligase concentration. Second, as strategies to improve the sensitivity and multiplexity of SNP detection, ligase detection reaction (LDR), ligase-dependent amplification, using three-different dyes labeled probes was introduced. The approaches are demonstrated that is sufficiently sensitive SNP detection without exponential amplification after ligation reaction and is a feasible validation tool for quantitative and multiplex population studies of SNPs. Lastly, the precisely detection of ligation-based reaction for a number of SNPs spread in the specific genes defined as highly polymorphic regions was improved to be good enough for discrimination of multiple SNPs on a single codon. To accomplish this, we employed gap filling ligation reaction and gap-forming probes to target highly polymorphic regions. By this approaches, closely multiple highly polymorphic regions could be accurately and simply analyzed without non-specific hybridization

Designing for EMC before it can be produced means that the device is required to meet the legal requirements for all the countries in the world such as those set by FCC and CISPR. Signal integrity (SI) refers to all the problems in high-speed designs such as ground/power bounce, crosstalk, reflection, and switching noise. These SI problems may lead directly to an EMI problem. Understanding and solving these problems before they occur will help reduce the cost and time spent in the project cycle.Plasma display panel (PDP) is a significant EMI source from its large panel sizes and the huge amount of driving current on its electrodes. High voltage currents flowing through the front panel are operated as multi-monopoles, or loop antenna devices with vertical and horizontal polarization fields, which can be radiated emission sources. It is important that PDP products ensure proper performance in an electromagnetic environment, maintaining an acceptable EMC.The main objective of this dissertation is to analyze EMC issues and to propose some EMI reduction techniques for PDP module related to SI problems. This dissertation consists of five chapters.Chapter 1 is the introduction of EMC and SI issues on PDP module. A basic description of radiation mechanisms and coupling paths are presented, and the value of EMC design with proper SI design is investigated.Chapter 2 discusses the topics related to EMC characteristics of PDP module. The PDPโ€™s operation mechanisms in its unit cell are investigated briefly to explain the radiation effects emitted from the multi-electrodes on its panel. In order to analyze the emission effects from the front panel during the sustain pulse and the address pulse, the current distribution factors on the three electrodes are calculated in the lumped and distributed models. The common and differential mode radiation characteristics are also researched to find and predict the type and the direction of the emission source radiated from the PDP panel. Finally, the low-frequency radio frequency interference issues, which often cause great trouble to amateur radio operators, are investigated using the 3m distance and near-field probe measurements. The results indicate that Y sustain board and Z board emit high noise levels at about 1.5MHz that may damage the operation of a radio transceiver.Chapter 3 introduces SI topics for PDP module. There are two main topics : how to design and model the real interconnects and how to improve SI of PDP module. First, full channel simulation (FCS) or co-simulation techniques are proposed. PDP data differential signaling (PDDS) channel on control board and X board are analyzed using FCS method. To verify the accuracy of all the components and interconnects, PDDS channels are measured in the time domain. The measurement results are in good agreement with the results from FCS.In order to improve SI of PDDS channels for high speed data transfers over 400Mbps or 800MBps, flexible flat cable are analyzed using FCS analysis. The optimized width and spacing of the channels and the modified FFC structures are proposed to minimize the signal distortion. Mesh ground structures using circular or rounded-corner aperture shapes on printed circuit board (PCB) are proposed and demonstrated to be superior to the conventional square-mesh apertures.Chapter 4 proposes the two modified guard trace structures : a guard trace with irregularly-spaced multi-vias and a guard trace with double-sided periodic grooves. First, the design of conventional guard traces with regularly-spaced vias for slotted ground plane may have some problems due to the slots in the ground plane. Modified guard traces using irregularly-spaced vias to solve these problems for the slotted ground planes are introduced. Experimental results prove the effectiveness of this method in improving the performance of SI. Furthermore, the reduced loop size of the ground plane of the proposed design reduced the amount of radiated emissions.Second, a novel guard trace with double-sided periodic grooves is proposed to effectively reduce far-end crosstalk (FEXT) between coupled traces. Through simulation and experiment, it is proved that the groove shapes on the guard trace are effective in increasing the mutual capacitance (with little change to the mutual inductance) when compared with the conventional guard trace. Chapter 5 is the conclusions of this dissertation. The most important results of this dissertation are summarized
