Clone Host Grade Applications
Polyclonal Rabbit Serum E B
The purine nucleoside adenosine modulates diverse physiological functions including induction of sedation, vasodilatation, suppression of cardiac rate and contractility, neurotransmitter release, inhibition of platelet aggregation and lipolysis. Adenosine released from cells interacts with membrane receptors (adenosine receptors, ARs). Based upon, biochemical and pharmacological criteria, ARs have been classified into A1, A2a, A2b and A3. The high affinity receptor A1 inhibits adenyl cyclase. Low affinity receptor A2a stimulates the cyclase via G proteins. A2a receptor is believed to cause vasorelaxation in coronary artery. Various, ARs and their subtypes have recently been cloned from several species. ARs belong to the superfamily of G-protein coupled receptors. They are predicted to contain 7 transmembrane domains. The N-termini are predicted to be extracellular. The C-termini is predicted to be cytoplasmic. There is an overall 30% homology among the four ARs. ARs are distributed throughout the body. Gene location of various ARs: A1 (Chromosome 1; q.31.3-32.2); A2a (Chromosome 22); A2b (Chromosome 17; p.11.2-12); A3 (Chromos.1).
Catalog #A0869-52D
ApplicationsSuitable for use in ELISA and Western Blot. Other applications not tested.
Recommended DilutionWestern Blot: 1:1000-1:5000 using ECL. Detects 79 and 39kD bands in cortical membranes from rat, pig, and lamb. The 79kD band can be converted to 39kD band by agonist or antagonist treatment and could represent a A1R dimers. A1R, photoaffinity labeled with 125I-R-AHPIA as 39kD band.
ELISA: 1:10,000-50,000 using 50-100ng A1R control peptide/well.
Optimal dilutions to be determined by the researcher.
Control Peptide A0869-52F
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, store at -20°C. Aliquots are stable for at least 12 months at -20°C.
