Most research in the life sciences involves a core set of molecular-based equipment and methods, for which there is no shortage of step-by-step protocols. Nonetheless, there remains an exceedingly high number of inquiries placed to commercial technical support groups, especially regarding problems. Molecular Biology Problem Solver: A Laboratory Guide asks the reader to consider crucial questions, such as:
* Have you selected the most appropriate research strategy?
* Have you identified the issues critical to your successful application of a technique?
* Are you familiar with the limitations of a given technique?
* When should common procedural rules of thumb not be applied?
* What strategies could you apply to resolve a problem?

A unique question-based format reviews common assumptions and laboratory practices, with the aim of offering a firm understanding of how techniques and procedures work, as well as how to avoid problems. Some major issues explored by the book's expert contributors include:
* Working safely with biological samples and radioactive materials
* DNA and RNA purification
* PCR
* Protein and nucleid acid hybridization
* Prokaryotic and eukaryotic expression systems
* Properly using and maintaining laboratory equipment
