Sourcing Research-Grade C221H342N46O68 Online

Research laboratories seeking to buy GLP-1 analogs with the molecular formula C221H342N46O68 online must source high-purity, analytical-grade compounds from verified USA suppliers. C221H342N46O68 represents a synthetic dual GLP-1/GIP receptor agonist evaluated exclusively for in vitro receptor kinetics and preclinical metabolic models, requiring third-party HPLC and mass spectrometry verification per lot.

Acquiring high-purity C221H342N46O68 research peptide materials online demands careful evaluation of vendor analytical standards. Because minor impurities, residual trifluoroacetic acid (TFA), or bacterial endotoxins can confound cell-based assays and animal models, principal investigators must insist on full chemical characterization before integration into any experimental protocol. PX1 Research supplies laboratory-grade peptides manufactured in ISO 17025 accredited and GMP-compliant facilities to ensure absolute reproducibility across research iterations.

Molecular Structure and Chemical Profile of C221H342N46O68

The empirical formula C221H342N46O68 corresponds to a 39-amino acid linear peptide engineered with specific side-chain modifications. Structurally, the sequence incorporates a C20 fatty diacid moiety attached via a linker to a lysine residue at position 20. This acylation design is engineered in preclinical settings to facilitate non-covalent binding to serum albumin, substantially extending the plasma half-life of the peptide during rodent pharmacokinetic studies.

With a calculated average molecular weight of approximately 4813.45 g/mol, C221H342N46O68 features two non-coded amino acid residues—α-aminobutyric acid (Aib)—at positions 2 and 13. These Aib substitutions confer structural rigidity and resistance to enzymatic degradation by dipeptidyl peptidase-4 (DPP-4). Investigating these molecular modifications allows researchers to study structural biology techniques aimed at optimizing peptide stability in aqueous and enzymatic environments. Researchers exploring our broader catalog of metabolic research peptides can compare these structural features against classical single-target peptide structures.

Preclinical Receptor Binding Mechanisms: Dual GLP-1R and GIPR Engagement

In vitro receptor binding assays demonstrate that C221H342N46O68 functions as a dual agonist at both the glucagon-like peptide-1 receptor (GLP-1R) and the glucose-dependent insulinotropic polypeptide receptor (GIPR). Pharmacological profiling indicates an imbalanced dual agonism profile: the molecule exhibits potencies comparable to native GIP at the GIP receptor, while displaying approximately five-fold lower potency relative to native GLP-1 at the GLP-1 receptor.

Biochemical research suggests that simultaneous activation of GIPR and GLP-1R signaling cascades triggers synergistic intracellular responses. In cultured pancreatic beta-cell lines, dual engagement stimulates adenylyl cyclase activity, elevating intracellular cyclic adenosine monophosphate (cAMP) levels. This dual-pathway recruitment provides a robust framework for investigating nutrient-stimulated insulin secretion, beta-cell survival pathways, and central nervous system metabolic regulation in rodent models of metabolic dysregulation.

Comparative Analysis: C221H342N46O68 vs. Single and Triple Agonist Peptides

To contextualize the pharmacology of C221H342N46O68, investigators frequently compare its dual-receptor activity against single-target and multi-target metabolic research peptides. For example, comparing C221H342N46O68 to a selective Semaglutide research compound highlights the distinct physiological consequences of isolated GLP-1R agonism versus combined GIP/GLP-1 activation in diet-induced obesity (DIO) mouse models.

Furthermore, novel multi-target candidate molecules like the Retatrutide triple agonist incorporate glucagon receptor (GCGR) activity alongside GIPR and GLP-1R engagement, providing a three-way comparative axis for tissue metabolic studies. Conversely, combining C221H342N46O68 assays with amylin receptor agonists like those detailed in our Cagrilintide preclinical guide allows research teams to map distinct neuroendocrine appetite and energy expenditure pathways across varied preclinical experimental groups.

In Vitro and Animal Model Evidence in Metabolic Research

Preclinical studies evaluating C221H342N46O68 in obese rodent models indicate pronounced effects on metabolic parameters. In DIO mice and Zucker diabetic fatty (ZDF) rats, administration of C221H342N46O68 results in dose-dependent reductions in cumulative food intake and significant body weight loss superior to equivalent doses of mono-selective GLP-1R agonists.

Hyperinsulinemic-euglycemic clamp studies in animal models reveal that C221H342N46O68 enhances peripheral insulin sensitivity, increases hepatic lipid oxidation, and decreases renal lipid accumulation. Furthermore, in vitro transcriptomic profiling of subcutaneous and visceral adipocytes shows upregulation of genes associated with mitochondrial biogenesis and thermogenesis. Investigators interested in these mechanisms can examine comprehensive study datasets in our public preclinical research database.

Quality Verification Standards: HPLC, MS, and Endotoxin Limits

When purchasing C221H342N46O68 online for precise analytical assays, peptide purity is the single paramount parameter. Non-target peptidic fragments or synthetic deletion sequences can interfere with receptor binding kinetics, yielding false positive or unreplicable data. PX1 Research subjects every synthesis lot to rigorous testing via Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) to confirm a chemical purity threshold of ≥99.0%.

In addition to HPLC purity, Electrospray Ionization Mass Spectrometry (ESI-MS) is performed to verify the precise monoisotopic mass of 4813.45 Da, confirming structural integrity without unwanted adducts. Finally, because cellular signaling and animal models are acutely sensitive to pyrogenic contamination, all batches undergo chromogenic Limulus Amebocyte Lysate (LAL) testing to confirm bacterial endotoxin levels remain strictly below <0.01 EU/mg.

Laboratory Handling, Storage, and Reconstitution Protocol

C221H342N46O68 is supplied as a sterile, lyophilized cake or powder designed exclusively for laboratory reconstitution. To preserve molecular stability, lyophilized vials must be stored in a controlled freezer environment at -20°C to -80°C, protected from light and atmospheric moisture. Under these conditions, the un-reconstituted peptide maintains chemical stability for up to 24 months.

For laboratory reconstitution, researchers should allow the vial to equilibrate to room temperature before adding a sterile solvent, such as Bacteriostatic Water or phosphate-buffered saline (PBS, pH 7.4). Gentle swirling is recommended to achieve full dissolution; aggressive vortexing must be avoided as mechanical shear stress can induce peptide aggregation or denaturation. Reconstituted liquid aliquots should be used immediately or stored at 4°C for short-term assays, avoiding repeated freeze-thaw cycles.
