The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human ADORA2a. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human ADORA2a....

Caffeine-d3 (Cay-18247) is an analytical reference material intended for use as an internal standard for the quantification of caffeine (Cay-22975) by GC- or LC-MS. Caffeine is a natural stimulant that is also used as a cutting agent for cocaine and heroin. This product is intended for research and forensic...

5'-Deoxy-5'-methylthioadenosine (MTA) is an intermediate in the generation of adenine and methionine that is produced by the decarboxylation of S-adenosylmethionine. This nucleoside is a potent agonist of adenosine receptors (Kis = 0.15, 1.13, 13.9, and 0.68 µM for A1, A2A, A2B, and A3, respectively). At higher...

Caffeine (CRM) (Cay-27970) is a certified reference material categorized as a stimulant. It is also used as a cutting agent for cocaine and heroin. This product is intended for analytical forensic applications. This product is also available as a general research tool (Cay-14118).Formal Name:...

Caffeine-d3 (CRM) (Cay-27971) is a certified reference material intended for use as an internal standard for the quantification of caffeine (Cay-27970, Cay-27970) by GC- or LC-MS. Caffeine is a natural stimulant that is also used as a cutting agent for cocaine and heroin. This product is intended for research and...

Caffeine-13C3 (CRM) (Cay-27972) is a certified reference material intended for use as an internal standard for the quantification of caffeine (Cay-22975, Cay-22970) by GC- or LC-MS.

Caffeine is a methylxanthine alkaloid naturally found in various plant parts that acts as an antagonist at central adenosine receptors at relevant physiological concentrations (IC50 = ~30 µM). It alters fatigue, mood, alertness, motor reaction time, vascular hemodynamics, and pain sensation. Caffeine has also been...

CGS 21680 is a potent, selective agonist of the adenosine A2A receptor (Ki = 11-46 nM). It is less effective at adenosine A1 and A3 receptors (Kis = 0.5-3.1 and 0.6-1 µM, respectively) and is without effect at adenosine A2B (Ki > 10 µM). CGS 21680 is commonly used to study the actions of the adenosine A2A receptor...

ZM 241385 is a potent antagonist of A2A adenosine receptors (pIC50 = 9.52 for displacement of 5'-N-ethylcarboxamidoadenosine from rat phaeochromocytoma cell membranes). It displays little or no activity at other A adenosine receptors. ZM 241385 is active in vivo. It acts as an inverse agonist at constitutively...

Adenosine is a purine nucleoside composed of adenine and ribose linked by a glycosidic linkage. It is an endogenous ligand of a family of four adenosine receptors, which serve diverse roles related to smooth muscle tone, central nervous system regulation, and cardiac function. Adenosine is a precursor for adenosine...

SCH 58261 is a competitive antagonist of the adenosine A2A receptor (Kis = 2.3 and 2.0 nM in rat and bovine brain, respectively). It is selective for the A2A subtype, displaying an A1/A2A selectivity ratio of 50-100-fold and does not interact with A2B or A3 receptors. SCH 58261 has been used to improve 6-hydroxy...

Xanthine amine congener (XAC) is a non-selective adenosine receptor antagonist with Kb values of 83, 25, and 15 nM for rat PC12 cells, human platelets that endogenously express adenosine A2A receptors, and rat fat cells that endogenously express A1 receptors, respectively. It reduces adenylate cyclase activity...
