Somatostatin-14 is supplied as white lyophilized powder with molecular formula C76H104N18O19S2 and molecular weight 1637.9. Somatostatin-14 is a cyclic tetradecapeptide that inhibits the release of growth hormone, insulin, glucagon and gastrin. Researchers apply it to pituitary cell cultures, pancreatic islet studies and gastrointestinal secretion assays. It is also used in neuroendocrine tumor research, where somatostatin receptor expression and signaling are central topics. In receptor pharmacology it provides a reference ligand for the five somatostatin receptor subtypes, and in analytical work it serves as a standard for peptide quantification in plasma. Standard pack sizes are 5 mg, 10 mg, 25 mg and 50 mg per vial, with larger quantities available on request. Vials are amber glass with butyl rubber stoppers and aluminum crimp seals, labelled with product name, lot number, CAS number, net mass and storage condition. Outer cartons use molded cushioning to protect the cake during transit, and orders containing several peptides are packed so that vials remain physically separated and cannot abrade one another. YIWU SHUNXIAN TRADING CO., LTD. stands as a beacon of precision and reliability in the realm of high-purity research-grade peptides and essential laboratory consumables. As a professional supplier, we are meticulously dedicated to empowering global research teams in their groundbreaking biochemical and life-science studies. With unwavering commitment, we bridge the gap between meticulously qualified peptide raw-material resources, each batch rigorously tested for purity and consistency, and a robust network of stable international logistics services, ensuring that cutting-edge research materials reach laboratories worldwide with the utmost efficiency and care. Our offerings provide researchers and industry partners with a dependable, trustworthy source, fostering an environment where innovation thrives, experiments yield accurate results, and laboratory development projects progress seamlessly, supported by the highest standards of quality and service. Conformity assessment relies on reverse-phase HPLC at 214 nm, supported by electrospray mass spectrometry for identity confirmation. Each lot is released only when the chromatographic purity reaches 99 percent or above, and residual trifluoroacetate, water content and endotoxin levels are recorded on the batch record. Analytical chromatograms and mass spectra are archived so that a research group can request the corresponding data for a specific lot number when a reviewer or internal audit requires supporting information. For quotations, packing options, lot documentation or delivery scheduling, contact Aurora on WhatsApp at +852 4423 6619, or write to 18963519387@163.com with the product name, required quantity and destination country. Including the intended application and any buffer or solubility constraints helps us recommend the most suitable pack size and confirm the practical transit window for your location. The lyophilized cake is stable for 24 months when kept sealed at minus 20 degrees Celsius in a dry environment. Brief exposure to ambient temperature during weighing does not compromise the material provided the vial remains closed. After reconstitution, keep solutions on ice during the experimental session and discard any remainder rather than refreezing. For peptides containing cysteine, consider adding a mild reducing agent if the assay is sensitive to disulfide-mediated oligomerization. Dispatch is normally within one to two business days after order confirmation, using tracked international courier services. Lyophilized peptides travel well at ambient temperature for typical transit periods, and gel packs are added when a destination or season makes temperature excursion a concern. Tracking details are provided at dispatch, and consolidated shipping is available when a laboratory orders several products at the same time.
