Thermo Scientific™ Guanidine-HCl

Thermo Scientific™ Guanidine-HCl

Thermo Scientific Pierce Guanidine-HCl can be easily dissolved and pH-adjusted to any concentration.

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 6M guanidine-HCl or 4M 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.
