3β-Cholic Acid-d4 Reference: 27376-5 An internal standard for the quantification of 3β-cholic acid by GC- or LC-MS
AG-041R Reference: 10010129-50 A potent CCK2/gastrin receptor antagonist that exhibits selective binding for CCK2 compared to CCK1; exhibits synergistic inhibitory effects on the cell viability of human gastric cancer cells when administered in combination with the selective COX-2 inhibitor NS-398
3β-Cholic Acid-d4 Reference: 27376-500 An internal standard for the quantification of 3β-cholic acid by GC- or LC-MS
(R)-Equol Reference: 10010172-1 An ER agonist that binds to ERα and ERβ with Ki values of 27.4 and 15.4 nM, respectively; demonstrates higher ER agonist activity at ERα compared to ERβ (EC50 = 66 and 330 nM, respectively)
Biotinidase Activity MaxSpec® Assay Kit Reference: 27544-1 Cayman’s Biotinidase Activity MaxSpec® Assay Kit includes the necessary reagents to quantify biotinidase enzyme activity in dried blood spots. The Biotinidase Activity MaxSpec® Assay Substrate has been designed to function as a highly selective substrate for biotinidase, which hydrolyzes the biotin moiety resulting in the formation of the Biotinidase Activity Assay Product. Using the Biotinidase Activity MaxSpec® Assay Kit, biotinidase activity may be quantified directly by LC-MS in combination with the Biotinidase Activity MaxSpec® Assay Internal Standard. ,
(R)-Equol Reference: 10010172-10 An ER agonist that binds to ERα and ERβ with Ki values of 27.4 and 15.4 nM, respectively; demonstrates higher ER agonist activity at ERα compared to ERβ (EC50 = 66 and 330 nM, respectively)
