Tiocianato di guanidina, 500 g

Highly chaotropic agent that potently destroys the three-dimensional structure of proteins, leading to denaturation. Guanidinium (iso)thiocyanate contains potent anionic as well as cationic groups, that form strong hydrogen bonds. It, therefore, can be used to break protein disulfide bonds as well as to disrupt hydrophobic interactions, and is added during RNA extraction in order to inhibit RNAse activity.
