Description

Igf-I (24-41) is a synthetic peptide fragment corresponding to amino acid residues 24-41 of the Insulin-like Growth Factor I (IGF-I) protein, with CAS number 135861-49-3. This specific sequence is critical for research into the structure-activity relationships and biological functions of IGF-I, a key regulator of cell growth and development. It is primarily utilized by research institutions and pharmaceutical developers in biochemical and pharmacological studies.

Application

• Biochemical Research: Used as a reference standard and tool peptide for studying the binding domains and signaling mechanisms of the full-length IGF-I hormone.
• Structure-Activity Relationship (SAR) Studies: Essential for mapping the bioactive regions of IGF-I and designing novel peptide analogs or mimetics.
• Antibody Production & Epitope Mapping: Serves as a specific antigen for generating and characterizing antibodies targeted against the 24-41 region of IGF-I.
• Cell Culture & In Vitro Assays: Employed in cell-based assays to investigate the effects of specific IGF-I domains on proliferation, differentiation, and metabolism.
• Pharmaceutical Development: Aids in the preclinical development of therapeutic agents targeting the IGF-I pathway, such as for oncology or metabolic disorders.
