Biotin-Amylin (1-37), human amidated

Biotin-Amylin (1-37), human amidated, is a synthetic peptide derivative of human amylin, also known as islet amyloid polypeptide (IAPP), that has been N-terminally labeled with biotin and C-terminally amidated. This modified peptide retains the full-length 37-amino acid sequence of native human amylin, a hormone co-secreted with insulin by pancreatic beta cells, and is structurally engineered for enhanced detection and assay compatibility. The biotin moiety enables high-affinity, non-covalent binding to streptavidin or avidin-conjugated probes, facilitating sensitive and selective capture or visualization in a variety of biochemical workflows. The amidated C-terminus mirrors the natural post-translational modification of amylin, preserving its structural integrity and functional relevance for research applications involving peptide-protein interactions, aggregation studies, and receptor binding analyses.

Affinity-based detection: The biotinylated form of amylin is highly advantageous for affinity-based detection and quantification in experimental systems. Researchers can utilize its biotin tag to enable robust and specific immobilization onto streptavidin-coated surfaces, such as microtiter plates, biosensor chips, or magnetic beads. This property is particularly valuable in enzyme-linked immunosorbent assays (ELISAs), Western blotting, and pull-down assays, where precise capture and subsequent detection of the peptide or its interacting partners are critical for elucidating amylin's biological roles and quantifying its presence in complex biological samples.

Protein-protein interaction studies: Biotin-Amylin (1-37), human amidated, is well-suited for dissecting the molecular interactions of amylin with its physiological partners, including the amylin receptor complex and other cellular components implicated in amyloidogenesis. By leveraging the biotin tag, investigators can perform co-immunoprecipitation or streptavidin-based pulldown experiments to map binding interfaces, characterize affinity constants, and identify novel interactors. These studies contribute to a deeper understanding of the mechanisms underlying amylin's physiological and pathological functions, particularly in the context of islet amyloid formation and metabolic regulation.

Aggregation and amyloidogenesis research: The propensity of human amylin to aggregate into amyloid fibrils is a central focus in diabetes research, as these aggregates are implicated in pancreatic beta-cell dysfunction. The biotinylated, amidated peptide serves as a precise tool for monitoring aggregation kinetics, visualizing fibril formation, and evaluating the impact of small molecules or chaperones on amyloid assembly. Researchers can exploit streptavidin-linked fluorescent or electron microscopy probes to track peptide aggregation in real time, facilitating detailed studies of amyloidogenesis and its modulation under various experimental conditions.

Receptor binding assays: The amidated version of biotinylated amylin closely mimics the native hormone's structure, making it suitable for receptor binding and signaling studies. Its biotin tag enables straightforward coupling to detection platforms, allowing for high-throughput screening of amylin analogs, receptor agonists, or antagonists. Such assays are instrumental in characterizing ligand-receptor dynamics, dissecting downstream signaling pathways, and screening for compounds that modulate amylin receptor activity, supporting both basic research and drug discovery efforts.

Peptide-based assay development: The dual modification—biotinylation and amidation—renders this peptide highly versatile for the development and optimization of custom peptide-based assays. Its compatibility with a range of detection and capture formats makes it an ideal standard or probe in multiplexed bioanalytical applications, including competitive binding assays, peptide mapping, and structural studies. The ability to reliably tether the peptide to various assay surfaces enables reproducible, scalable experimental workflows across academic, pharmaceutical, and biotechnology laboratories investigating amylin biology or related peptide hormone systems.
