The ChemiScreen SST4 Somatostatin Receptor Membrane Preparation is derived from proprietary stable recombinant cells to ensure high levels of SSTR4 surface expression. ChemiScreen membrane preps can be used to screen for ligand binding affinities using a competitive radio-labeled ligand approach. Increased binding affinities will lead to higher radioactive signal. Membrane preps contain 1 mL of 1 mg/mL frozen membranes derived from a stably modified clonal cell line which was chosen for optimal receptor expression.
