SATP is a colorimetric solvent extraction reagent for Cu, In, Ni, and Sn. It is insoluble in water, but soluble in organic solvents.

Cross-linking reagent: Hetero-bifunctional cross-linking reagents have activated esters and maleimide reactive groups. These functional groups react with amines and sulfhydryl groups of proteins, respectively. Enzyme-labeled haptens are prepared using hetero-bifunctional cross-linking reagents such as EMCS or GMBS. The cross-linking reaction requires neutral pH and mild temperature because it is necessary to maintain enzyme activity and antibody titers in the cross-linking reaction.

SIN-1, a metabolite of the vasodilator molsidomine, is utilized to separately estimate the effectiveness of NO and peroxynitrite with other NO donors. Application: Spontaneous NO, peroxynitrite donor

SPDP, a hetero-bifunctional reagent, is useful for bridging two different proteins, such as enzymes and antibodies.

SAT-3 is a stable, highly water-soluble o-Tolidine analog. It is easily oxidized by peroxidase and hydrogen peroxide into a green dye at pH 4-6. 

Sodium polysulfides (Na2Sn) are sulfane sulfur donors which have simple structures, and exist as hydrogen polysulfides in an aqueous solution depending on pH. These reagents are necessary to for research and analysis of sulfane sulfurs in vivo.
