Reagent Preparation: Theoretical and Practical Discussions

One of the most important requirements for the successful completion of any biochemical protocol is to prepare reagents accurately. This unit describes general guidelines for the preparation of reagents, use of clean glass- and plasticware, use of high-purity reagents, safe handling of chemicals and biochemicals, use of high-purity distilled or deionized water, accurate weighing, pipetting, and pH measurement, and avoidance of chemical or microbial contamination of reagents and use of sterile reagents. Different units of concentration used for preparation of reagents or buffer solutions are described. This unit also includes a section for the preparation of buffer solutions with a practical example.
