Guanidine hydrochloride has commonly been used for the isolation of RNA, to denature globular proteins and for protein refolding studies. It can also be used to facilitate the generation of tryptic peptides for analysis of complex protein samples.

Guanidine Thiocyanate has commonly been used for the isolation of RNA, to denature globular proteins and for protein refolding studies. It can also be used to facilitate the generation of tryptic peptides for analysis of complex protein samples.

Boric Acid can be used in biopharmaceutical buffer formulations (both upstream and downstream).

DTT, Dithiothreitol can be used for maintaining thiol groups in a reduced state during protein processing, isolation, and denaturing.
