Biography
Ayaz Najafov
Ayaz was born in Baku, Azerbaijan and as a high school student, participated in local and international biology Olympiads, where he had won several gold, silver, and bronze medals. He obtained his BSc and MSc degrees in Molecular Biology and Genetics from Bosphorus University, Istanbul, Turkey, and got a 2-year training in Biochemistry as an intern at Baylor College of Medicine, Houston, TX, United States. Ayaz pursued his PhD in Biochemistry at MRC Protein Phosphorylation Unit at Dundee University, Scotland, United Kingdom in Prof. Dario Alessis lab. Ayaz is currently a postdoctoral fellow in Prof. Junying Yuans lab at Harvard Medical School, Cell Biology Department.
Gerta Hoxhaj
Gerta was born in Fier, Albania. She obtained her BSc degree in Molecular Biology and Genetics, as well as a second major in Chemistry from Bosphorus University, Istanbul, Turkey. Gerta pursued her PhD in Biochemistry at MRC Protein Phosphorylation Unit at Dundee University, Scotland, United Kingdom in Prof. Carol MacKintoshs lab. Gerta is currently a postdoctoral fellow in Prof. Brendan Manningss lab at Harvard T.H. Chan School of Public Health, Department of Genetics and Complex Diseases.
Preface
This book was written with an aim of providing researchers practicing molecular biology, whether at their beginner or expert stage, with a handy tool and reference for setting up, performing, optimizing, and troubleshooting polymerase chain reaction (PCR). We believe that this book will provide tremendous assistance for solving problems associated with challenging cases of PCR.
This book does not provide the reader with vast details of the PCR theory and the multiple applications of the technique. As this book is a laboratory guide, the emphasis here was made on the technical aspects of employing PCR as a tool in molecular biology laboratories and the issues were described in bench terms, which makes the book more comprehendible to the end users of the technique.
General optimization and troubleshooting strategies, as well as a detailed guide for addressing specific PCR problems, tips and tricks developed and learned through years of experience with PCR and its various applications, several special cases for PCR, and appendices with protocols and other useful information related to PCR, make this book a practical reference all molecular biology laboratories can benefit from.
Acknowledgments
We would like to thank Ali Kavak, Aydin Mammadov, and Cafer Ozdemir for their comments and suggestions during the preparation of this book.
Note to the Reader
All agarose gel images published in this book were inverted (negative) to save ink/toner used to publish this book.
As DNA polymerase is the only enzyme in the standard PCR setup, and as there are many other DNA polymerases (besides Taq) used in modern molecular biology labs, we will refer to DNA polymerase as the enzyme.
We will use the term target for the specific sequence that is intended to be amplified using a set of primers.
Chapter 1
Introduction
Abstract
Origins of polymerase chain reaction (PCR) and its history are briefly introduced in this chapter. The components of the PCR are introduced and the effect of the component concentrations on the fidelity, specificity, and efficiency of PCR are explained. Various thermostable DNA polymerases that are currently being used in the PCR setups around the world are listed. The power of the cyclic and the exponential nature of PCR, the effect of the reaction reaching the plateau, and how this affects the specificity and yield of the reaction are discussed. Finally the rise in the popularity of this method since it was first introduced by Dr. Kary Mullis in 1983 is illustrated.
