"Systems Range of Antibodies for G Protein-Coupled Receptors" refers to a collection of antibodies designed to target G protein-coupled receptors (GPCRs) across various biological systems. GPCRs are a large family of cell surface receptors that play a critical role in transmitting signals from the extracellular environment to the interior of cells. They are involved in a wide range of physiological processes, including sensory perception, neurotransmission, hormone regulation, and immune response.
