About the BookAbout the AuthorTable of Contents

The book helps undergraduate, postgraduate and research students to perform basic experiments in biotechnology. The laboratory protocols are simple to understand by students from different scientific backgrounds. Each laboratory exercise contains an introductory unit, protocol and easy-to-follow instructions for reagent preparation. The methods and protocols given here aim to make students ready for independent research in biotechnology laboratories. The protocols include

DNA Isolation
Molecular Biology Methods
RNA Isolation
Useful Information for Molecular Biology Methods
Working with DNA
Preparation of Solutions
