Effect of βarr-2 knockout on lung and ASM β-AR density
| WT ASM | βarr-2-KO ASM | WT lung | βarr-2-KO lung | |
|---|---|---|---|---|
| β-AR density | 80.3 ± 25.2 | 88.9 ± 13.8 | 444 ± 56 | 471 ± 38 |
Membranes from WT and βarr-2-KO mice were prepared as described in Materials and Methods. β-AR density was measured as radioligand binding (fmol/mg protein). Results are expressed as means ± sd of 2 (lung) or 3 (ASM) experiments.
