Description

Irbp (1-20), Human CAS NO 298202-25-2 is a synthetic peptide fragment corresponding to the first 20 amino acids of the human Insulin-like Growth Factor Binding Protein (IGFBP). This high-purity reference standard is critical for research and development in endocrinology and metabolic studies. It is primarily utilized by pharmaceutical R&D teams and academic researchers focused on growth factor signaling pathways, diabetes, and cancer biology.

Application

• Biochemical Research: Used as a reference standard in the study of IGF-1 and IGF-2 binding kinetics and protein-protein interactions.
• Assay Development: Serves as a critical component in the development and validation of ELISA and other immunoassays targeting IGFBP.
• Pharmaceutical R&D: Employed in drug discovery programs targeting the IGF axis for metabolic disorders and oncology applications.
• Cell Culture Studies: Utilized to investigate the effects of IGFBP fragments on cell proliferation, differentiation, and apoptosis in vitro.
• Quality Control: Acts as a system suitability standard in the analytical testing of related biopharmaceutical products.
