Detection of β₁ and β₂ adrenergic receptors on HMC-1 cell by flow cytometry analysis. Resting HMC-1 were harvested and stained with a purified rabbit polyclonal antibody to either β₁ or β₂ adrenergic receptor and counter stained with a secondary goat anti-rabbit FITC conjugated antibody. Normal rabbit serum and the FITC conjugated goat anti-rabbit Ig G antibody was used as a staining control.
