This much-needed new addition contains updated information for commercial reagents available since the last edition while maintaining the same organization (outline) of the previous edition. The book is written for those with a basic knowledge of chemistry, and MANY examples (with exact instructions) are provided. Greg T. Hermanson is the "go to guy" for this kind of information, and has delivered (once again) the ultimate text for this kind of information. (I only wish it were available in spiral binding...)
