采用放射配体（１２５ＩＢＥ２２５４）结合分析，证明狗胸主动脉平滑肌存在α１肾上腺素受体，其最大结合容量为１９９±３１ｆｍｏｌ／ｍｇ·蛋白，ＫＤ为１３９±２７ｐｍｏｌ／Ｌ，其中３／４以上属α１Ｂ亚型，另外１／４左右属α１Ａ亚型。
Radioligand (125IBE2254) binding analysis showed that α1 adrenergic receptor was present in the smooth muscle of dog thoracic aorta. Its maximum binding capacity was 199 ± 31 fmol / mg · protein, KD was 139 ± 27 pmol / L, of which more than 3/4 α1B subtype, the other 1/4 about α1A subtype.
