Background:

IC50: N/A

LiCl is a typical ionic compound, though the small size of the Li+ ion makes its properties not seen for other alkali metal chlorides, such as the extraordinary solubility in polar solvents and hygroscopic properties.

In vitro: Though precipitation with a monovalent cation or alcohol is much more widely used, LiCl has been frequently used to precipitate RNA. LiCl precipitation gives various advantages over other methods: LiCl does not precipitate DNA, protein and carbohydrate efficiently. LiCl can be also used for removing translation inhibitors or cDNA synthesis from RNA preparations. LiCl can be also used as a simple rapid method for recovering RNA from in-vitro transcription reactions [1]. In addition, a method for isolation of large, translationally active RNA samples has been presented. In this study, the procedure included homogenization of samples in 5 m guanidine monothiocyanate followed by direct precipitation of RNA from the guanidinium by 4 m LiCl. The advantages of this method include simplicity, speed, avoidance of ultracentrifugation, and its applicability to large numbers of samples. The method yielded large mRNA precursors up to 10 kb [2].

In vivo: Currently, there is no animal data reported.

Clinical trial: Up to now, LiCl has not been used clinically.
