Description
Product Description
Bombesin is a biologically active peptide originally identified for its role in neuroendocrine signaling and gastrointestinal regulatory pathways. As a well-characterized peptide ligand, it is widely used in research focused on peptide–receptor interactions, signal transduction, and neuropeptide physiology.
In laboratory studies, Bombesin is commonly applied to investigate gastrin-releasing peptide (GRP) receptor family signaling, intracellular calcium mobilization, and downstream kinase activation pathways. Its defined amino acid sequence enables reproducible evaluation of receptor binding affinity and signaling specificity across different experimental models.
This peptide also serves as an important reference compound in oncology-related research, where Bombesin receptor expression is explored in various tumor cell models. Researchers use it to study receptor overexpression patterns, ligand-induced signaling responses, and comparative peptide analog activity.
Supplied as a lyophilized powder, Bombesin offers excellent stability during storage and transport. The material can be readily reconstituted for use in in vitro assays, receptor binding studies, and biochemical experiments requiring precise peptide dosing.
Each batch of Bombesin undergoes strict analytical quality control, including chromatographic purity assessment and molecular identity verification. This ensures batch-to-batch consistency and reliable performance in advanced peptide biology, receptor pharmacology, and neuroendocrine research programs.
