Unboiled various whole cell extracts (30 μg) were separated by 10% SDS-PAGE, and the membrane was blotted with Adenosine A2a Receptor antibody [HL4086] (GTX642525) diluted at 1:500. The HRP-conjugated anti-rabbit IgG antibody (GTX213110-01) was used to detect the primary antibody, and the signal was developed with Trident ECL plus-Enhanced. Corresponding RNA expression data are based on Human Protein Atlas program.
