  2. Adenosine Receptor
  3. MRS1334

MRS1334 is a potent and selective human adenosine A3 receptor antagonist with Kis of 2.69 nM, >100 nM, >100 nM for hA3, rA1, rA2A, respectively. MRS1334 blocks the protective effect of Cl-IB-MECA leading to significant bradycardia and elevated ST segment. MRS1334 is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
