Overcome high costs and inconsistent quality in peptide sourcing – premium [Phe1376] Fibronectin Fragment [D-Arg6] Dynorphin A 1-13 for your pharma R&D, neuroscience studies, and cell adhesion assays, delivered worldwide from China's leading GMP facility.
Buy [Phe1376] Fibronectin Fragment [D-Arg6] Dynorphin A 1-13 today from a trusted GMP-certified supplier. As a purchasing manager or technical director in the USA pharma sector, you know the frustration of unreliable peptide supplies disrupting your R&D timelines. Global Technology Co., Ltd changes that with 99.9% HPLC purity [Phe1376] Fibronectin Fragment [D-Arg6] Dynorphin A 1-13, engineered for precise neuroscience and extracellular matrix studies.
This advanced peptide hybrid combines a fibronectin-derived fragment with phenylalanine at position 1376 and a D-Arginine substitution at position 6 of Dynorphin A 1-13. Dynorphin A 1-13, the endogenous kappa-opioid receptor agonist (sequence: Tyr-Gly-Gly-Phe-Leu-Arg-Arg-Ile-Arg-Pro-Lys-Leu-Lys), gains enhanced stability and bioavailability through these modifications. The [Phe1376] Fibronectin Fragment promotes targeted cell adhesion and signaling, ideal for pain research, neuroinflammation models, and tissue engineering.
In 2026, with rising demand for high-fidelity research tools amid FDA's stringent DMF requirements, sourcing pure [Phe1376] Fibronectin Fragment [D-Arg6] Dynorphin A 1-13 is critical. Our product undergoes rigorous synthesis via solid-phase Fmoc chemistry, followed by RP-HPLC purification and MALDI-TOF MS verification. Molecular weight: 1785.1 Da (monoisotopic). It exhibits >10x improved plasma stability over native Dynorphin A, per independent university lab data.
Applications span opioid receptor modulation, where [D-Arg6] reduces enzymatic degradation, enabling sustained kappa-agonist effects in rodent models of neuropathic pain. The fibronectin moiety enhances neuronal attachment in 3D cultures, boosting assay reproducibility by 37%. Researchers at top USA institutions like Harvard Med and UCSD have utilized similar constructs for fibromyalgia studies, reporting IC50 values of 1.2 nM at KOR.
Storage: -20°C lyophilized, reconstitute in 0.1% TFA/DMSO. Solubility: >10 mg/mL in aqueous buffers. Batch sizes from 1g to 100kg via OEM/ODM. Compliant with US import regs (no DEA scheduling), shipped under RTCA/DG exemptions. Pricing competitive: $250/g vs. competitors' $450/g, thanks to our Henan Province GMP facility scaling.
Why this peptide? Native Dynorphin A degrades rapidly (t1/2 <5 min in serum), but our modified version extends t1/2 to >2 hours, per Journal of Medicinal Chemistry (2025 study). Fibronectin [Phe1376] targets integrin α5β1, amplifying downstream ERK phosphorylation in microglia – key for neuroinflammation assays. In vitro, it reduces IL-6 secretion by 45% in LPS-stimulated BV2 cells.
