Kinase experiment:

For saturation as well as displacement studies, rat lung homogenate is incubated in either Hepes-buffer or blank human or rat plasma yielding 50 μg protein per well in a total assay volume of 300 μL. To ensure equilibrium conditions (see binding kinetics), the samples are maintained for 60 min at 25℃ under continuous rotation. All experiments are carried out in duplicate, and the results are confirmed with n=3-5 replicates over the following days[1].

SL910102 is a nonpeptide angiotensin AT1 receptor antagonist.

SL910102 (SL 91.0102-90 DL) is a unlabelled nonpeptide AT1-antagonist, which is tested for its ability to compete with [125J](Sar1-Ile8)-angiotensin II for specific AT1-receptor sites in rat lung homogenate[1].
