Gene Expression Systems: Using Nature for the Art of Expression offers detailed information on a wide variety of gene expression systems from an array of organisms. It describes several different types of expression systems including transient, stable, viral, and transgenic systems. Each chapter is written by a leader in the field. The book includes timelines and examples for each expression system, and provides an overview of the future of recombinant protein expression.
Key Features
* Provides detailed information on expression systems
* Covers a variety of promoters and host organisms enabling researchers to tailor protocols to their specific needs
* Includes timelines and examples
* Compares pros and cons of each method

Journalists and Confidential Sources explores the fraught and widespread reliance by journalists on anonymous sources, whistleblowers, and others to whom they owe an obligation of confidentiality. It examines the difficulties afflicting such relationships; analyses the deteriorating "right to know" and freedom of expression frameworks; and explores solutions and reforms. The book discusses key Australian and international source protection ethics rules, statutes, court cases, law enforcement actions, and case studies. It highlights weakness in journalists' professional practice codes governing confidentiality obligations; discusses inadequate journalistic appreciation of the importance of establishing clear terms and conditions underpinning confidentiality obligations; and identifies shortcomings in the law governing source protection. The book argues that despite source protection being widely recognised as an important ideal, source protection is under sustained assault, thereby undermining public access to information, and democracy itself. The work focusses on Australia but takes into account source protection in the United Kingdom, the United States, Canada, and New Zealand. This timely contribution to the global discussion on the subject will greatly interest journalists, scholars, educators, and students especially in the areas of media law and policy, journalism, media and communication studies, and public relations; the legal fraternity; and anyone who communicates with journalists.
