QUICK LINKS

Equilin 3-Sulfate Sodium Salt, stabilized with TRIS (tris(hydroxymethyl)aminomethane), at a concentration of 50% w/w, is a chemically modified form of equilin, a naturally occurring estrogen found in the urine of pregnant mares. This compound is particularly notable for its application in biochemical research, especially in studies related to estrogenic activity, and the endocrine system. The inclusion of TRIS not only stabilizes the compound but also makes it compatible with a wide range of physiological pH values, ensuring that the equilin 3-sulfate maintains its structural and functional integrity during experimental procedures.
