Human Follicular Conadotropin Releasing Peptide (Hf-GRP)

Human Follicular Conadotropin Releasing Peptide (Hf-GRP) is a synthetic research peptide in the bombesin / gastrin-releasing peptide (GRP) family. Bombesin and mammalian gastrin-releasing peptide are members of the bombesin-like peptide family and are used extensively in GRP-receptor research. Their C-terminal region contains key determinants for receptor binding and activation, making terminal fragments, substitutions, and modified analogs useful tools for defining GRPR recognition, agonism/antagonism, internalization, and structure-activity relationships.

• receptor-binding
• competition assays
• functional signaling assays
• enzymatic-processing or stability studies
• antibody controls
• LC-MS/HPLC method development
• comparative structure-activity experiments

For a fragment, residue-substituted analog, stereochemical variant, labeled peptide, or terminally modified form, experimental behavior should be evaluated for the exact construct rather than assumed to match the native parent peptide. Sequence-dependent solubility, aggregation, adsorption, and stability should be considered when selecting reconstitution and assay conditions.
