Cardiac distribution of specific ¹²⁵I-Hpp-Aca-SDKP receptor binding in rats as visualized by quantitative in vitro autoradiography

	Left Atrium	Right Atrium	Left Ventricle	Right Ventricle	Septum
Specific binding, dpm/mm²	25.8 ± 3.5	23.6 ± 1.6	34.7 ± 2.6	29.6 ± 3.9	29.3 ± 2.2

Values are means ± SE. Specific binding was determined as the difference between total binding and binding in the presence of excess unlabeled Hpp-Aca-SDKP (10 μM). Hpp, 3-(p-hydroxyphenyl)-propionic acid; SDKP, N-acetyl-seryl-aspartyl-lysyl-proline. There were no significant differences in specific ¹²⁵I-labeled Hpp-Aca-SDKP receptor binding between different cardiac structures (one-way ANOVA).
