FollistatinActivinTGF-β Superfamily
A research overview of Follistatin, a glycoprotein studied for its role as a ligand trap for activin, GDF-8, and select BMP family members within the TGF-β superfamily. Covers domain architecture, isoform distinctions, SMAD signaling pathway inhibition, and the difference between recombinant and synthetic truncated forms available for research. For research purposes only.
GLP-1Incretin PeptideGLP-1 Receptor
A research overview of glucagon-like peptide-1 (GLP-1), an incretin peptide studied for its binding kinetics at the GLP-1 receptor, a class B G protein-coupled receptor, and the intracellular cAMP signaling cascade that receptor activation initiates. Covers active fragment structure, GLP-1R engagement mechanism, receptor pharmacology, and what distinguishes GLP-1 biology at the receptor level. For research purposes only.
IGF-1 LR3Insulin-like Growth FactorReceptor Kinetics
A research overview of IGF-1 LR3, a structurally modified analog of insulin-like growth factor 1 studied for its altered binding protein affinity profile and IGF-1 receptor engagement kinetics. Covers molecular structure, the LR3 modification rationale, downstream signaling characterization, and what distinguishes it from native IGF-1 in research models. For research purposes only.
Peptide SourcingAnalytical ChemistryCertificate of Analysis
A technical look at what Certificate of Analysis data actually measures, how HPLC purity quantification and mass spectrometry identity confirmation work, and why these standards matter for receptor binding and cell-based research assays. For research purposes only.
