How do you make guanidine hydrochloride solution?
Guanidine hydrochloride is commercially available from Sigma Aldrich. The MW is 95.5 therefore one mole weight 95.5 g. If you want to prepare one liter of solution you need 8 x 95.5 g of this salt. It should be dissolved in the minimum of water and then take it to the required volume.
How do you make 4m guanidine HCl?
Take 0.4726g of Guanidine thiocyanate (molecular biology grade, ≥99% pure), add it to a graduated eppendoff tube. Add 0.5 ml of you buffer from above and vortex mix thoroughly. Now gradually add more buffer to make the volume up to 1ml.
What does guanidine HCl do?
Guanidine hydrochloride is indicated for the reduction of the symptoms of muscle weakness and easy fatigability associated with Eaton-Lambert syndrome. It is not indicated for treating myasthenia gravis. It apparently acts by enhancing the release of acetylcholine following a nerve impulse.
How do you dissolve guanidine?
Guanidinium Lysis Buffer (GLB) To a 250ml beaker, add 0.58ml Stock Solution A, 9.42ml Stock Solution B, and 57.3g powdered Guanidine Hydrochloride. Stir the solution until the powder is completely dissolved. Adjust the pH to 7.8 using 1M NaOH or 1M HCl.

How do you make 6 M guanidine HCl?
How do you make guanidine thiocyanate solution?
Dissolve 120 g of Thiocyanate Guanidine (GuSCN) in 100 ml of 0.1 M Tris hydrochloride, pH 6.4. Dissolution of GuSCN was facilitated by heating in a 60 to 65°C water bath under continuous shaking. Buffers L2 is stable for at least 3 weeks at room temperature in the dark.
Why is guanidine a strong base?
It is a highly stable +1 cation in aqueous solution due to the efficient resonance stabilization of the charge and efficient solvation by water molecules. As a result, its pKa is 13.6 meaning that guanidine is a very strong base in water; in neutral water, it exists almost exclusively as guanidinium.
How do you remove guanidine HCl?
The refolding of proteins from the insoluble cellular fraction is commonly accomplished by solubilizing the protein in a chaotropic agent, such as guanidine hydrochloride (GuHCl) or urea, and then removing the denaturant by dialysis or rapid dilution.
Does guanidine expire?
