Thermo Scientific Pierce 8M Guanidine-HCl Solution is an accurately formulated, ready-to-use solution of guanidine hydrochloride, that can be easily diluted and pH-adjusted to any concentration below 8M.
In addition to increasing solubility of hydrophobic molecules, guanidine is a general protein denaturant, unfolding proteins and altering their three-dimensional structure. Consequently, some proteins will be irreversibly altered upon interaction with guanidine solutions and may lose their binding function. Before any large-scale use of guanidine, it is best to test a small sample and determine whether the denaturing effects will adversely affect the intended use of the protein.
Highlights (of 8M Guanidine-HCl Solution):
- Any concentration below 8M guanidine can be quickly and easily prepared.
- No wasting valuable research time weighing and dissolving guanidine crystals
- Free from UV absorbing materials in the range of 225-300nm
- Free from heavy metal contaminants
- Free from degradation products such as ammonia
- Excellent stability
Applications for Guanidine Hydrochloride:
- Solubilizing proteins from inclusion bodies
- Increasing solubility of hydrophobic peptides and proteins
- Denaturing proteins
Product Details:

Chaotropes, substances that disrupt the structure of water interactions, help to solubilize hydrophobic proteins and peptides for a variety of biological purposes. For example, hydrophobic peptides and proteins may be dissolved in coupling buffer containing either 6 molar guanidine-HCl or 4 molar urea prior to immobilization on AminoLink Plus Support to create an affinity column. However, because the degradation products of guanidine and urea include ammonia, which contains a primary amine that will compete for reaction to the support, urea and guanidine solutions must be prepared with high quality reagents immediately before use.
