PRL-S1 5 MG

$40.00

PRL-S1 is Peptiva Research Labs' house designation for a synthetic long-acting receptor-agonist peptide in the semaglutide research class, engineered to selectively activate the glucagon-like peptide-1 (GLP-1) receptor, a class B G-protein-coupled receptor. Structural modifications associated with this class are typically intended to extend molecular half-life, making PRL-S1 a useful reference tool for studying sustained single-receptor incretin signaling. In laboratory settings, researchers study PRL-S1 in receptor-binding and cyclic-AMP reporter assays, transfected cell lines, and preclinical models to characterize GLP-1 receptor activation, signaling kinetics, and gene-expression responses associated with appetite and glucose-homeostasis circuits. In-vitro work also examines receptor internalization, beta-arrestin recruitment, and the durability of signaling output relevant to long-acting agonist design. These investigations are mechanistic and exploratory, with no therapeutic, weight-loss, or veterinary intent. Peptiva Research Labs supplies it as a research-grade reference compound, HPLC-verified with a COA available. For Research Use Only, not for human or veterinary use.

Frequently asked questions

What is PRL-S1?
PRL-S1 is Peptiva's house code for a synthetic long-acting agonist in the semaglutide research class that selectively activates the GLP-1 receptor. It is studied as a reference tool for sustained incretin signaling. It is offered strictly for laboratory research.
What receptor mechanism does PRL-S1 represent?
It acts as a selective agonist at the GLP-1 receptor, a class B G-protein-coupled receptor that signals through cyclic-AMP. Researchers study it to model long-acting single-receptor activation and signaling durability. All study is in-vitro or preclinical.
How is PRL-S1 stored and reconstituted?
Lyophilized peptide is typically kept desiccated at -20°C and protected from light. For experiments it is commonly reconstituted in sterile or bacteriostatic water and aliquoted to reduce freeze-thaw cycles. Reconstitution should follow the laboratory's own protocols.
