Guanidine Thiocyanate is a strong chaotropic protein denaturant, and is intended for use in isolation of nucleic acid.Guanidine Thiocyanate is an ultrapure, molecular biology grade reagent. It is free of detectable nuclease and protease activity and is a strong protein denaturant, as both the guanidinium cation and the thiocyanate anion are chaotropic agents. It is provided in one bottle containing 500 g. It is recommended for isolation of RNA, especially for tissues such as pancreas with high levels of RNase activity. In solution, it is known as guanidinium thiocyanate. Guanidine Thiocyanate is thoroughly tested for contaminating nonspecific endonuclease, exonuclease, and RNase activity.

Guanidine isothiocyanate, RNA / DNA extraction, raw material for new coronary pneumonia detection reagents
Guanidine thiocyanate (GITC) is a powerful chaotropic agent that was first synthesized in the mid-20th century. It was developed while exploring the unique properties of guanidine derivatives to disrupt molecular structure. GITC quickly gained fame for its powerful ability to denature proteins and nucleic acids and is of great value in molecular biology and biochemistry.
The chemical formula of guanidine thiocyanate is CH5N3â?¢CHNS. It is a colorless to pale yellow crystalline solid that is highly soluble in water and organic solvents. The compound has a guanidine group attached to a thiocyanate ion, which gives it its powerful chaotropic properties. This structure disrupts hydrogen bonds, effectively denaturing biomolecules.

Powder: Normal 500g /bottle,or 25KG Drum, or satisfy client's need.(can talk with us online directly)
Guanidine thiocyanate is a white crystal, melting point 116 ~ 121�ºC, 20�ºC, 6mol/L in water pH value of 4.5 ~ 6, the solubility is completely dissolved. It is a kind of uncoupling agent, is a kind of strong protein denaturant Chemicalbook, can dissolve the protein, and make the protein secondary structure disappear, the cell structure degradation, nuclear protein and nucleic acid separation quickly. For denatured lysed cells; RNA and DNA were extracted without RNA enzyme and DNA enzyme activity.
Application & Function
1. chaotropic agenti and the strong denaturation agent, used for the degenerative lysis cells;
2. Extract RNA and DNA;
3. can be used as a DSSC absorber to improve the DSSC conversion rate.
