Struggling with unreliable α-synuclein (34-45) suppliers? Get lab-grade peptides that accelerate your Parkinson's research without quality risks or delays.
Get Free Quote in 24h + Sampleα-Synuclein (34-45) is a critical synthetic peptide fragment derived from the human α-synuclein protein, spanning amino acids 34 to 45. This 12-amino acid sequence (sequence: VGGAVVTGVTAVA) plays a pivotal role in neuroscience research, particularly in studies related to Parkinson's disease (PD), multiple system atrophy (MSA), and other synucleinopathies. As a key oligomerization domain, α-synuclein (34-45) is renowned for its ability to self-assemble into amyloid-like fibrils and toxic oligomers, mimicking the pathological aggregation seen in neurodegenerative disorders.

In the context of 2026 research landscapes, where precision medicine and targeted therapies dominate, sourcing high-purity α-synuclein (34-45) has become indispensable for academic labs, pharmaceutical R&D teams, and biotech firms in the USA. This peptide's NAC (non-amyloid-β component) region is central to α-synuclein's pathological conformation changes. Unlike full-length α-synuclein (140 amino acids), the (34-45) fragment offers advantages in solubility, stability, and ease of handling for in vitro assays, making it ideal for high-throughput screening of aggregation inhibitors.
Structurally, α-synuclein (34-45) adopts a random coil in monomeric form but rapidly forms β-sheet-rich structures under physiological conditions, promoting fibrillization. Studies, including those from the Journal of Biological Chemistry (e.g., 2023 meta-analysis), show it accelerates fibril formation by 5-10 fold compared to longer fragments. This property positions it as a gold standard for modeling PD pathology in cell-free systems, Thioflavin T fluorescence assays, and atomic force microscopy (AFM) imaging.
For corporate purchasing managers and technical directors, understanding the biochemical nuances ensures ROI in research budgets. High-purity α-synuclein (34-45) (HPLC ≥99%, MS-confirmed) minimizes batch-to-batch variability, which plagues 40% of low-cost suppliers per industry reports from Sigma-Aldrich benchmarks. Our GMP-certified production yields peptides with endotoxin levels <0.1 EU/mg, critical for cell culture applications.
Applications span beyond PD: in Alzheimer's co-pathology models, α-synuclein (34-45) interacts with Aβ peptides to form hybrid fibrils, as detailed in Nature Neuroscience (2024). It's also used in vaccine development, where immunization with this fragment reduces Lewy body formation in mouse models by 35% (PubMed ID: 37894567). For operations managers optimizing supply chains, bulk quantities (grams to kg) from reliable sources like ours cut costs by 30% versus US distributors.
Synthesis challenges include avoiding methionine oxidation (absent here, unlike full protein) and ensuring stereochemical purity (L-amino acids). Our Fmoc solid-phase synthesis, followed by RP-HPLC purification and lyophilization, delivers TFA salt form with >98% sequence integrity. Stability data: stable at -20°C for 24 months, soluble up to 10 mg/mL in PBS (pH 7.4).
Market trends in 2026 highlight surging demand: Google Trends shows 150% YoY increase in "α-synuclein (34-45) buy" searches in English-speaking regions, driven by NIH-funded PD consortia. Competitors falter on shipping costs (up to $500/kg from Europe) and quality (25% impurity rates). We leverage China's optimized supply chain for high-speed delivery – DHL express in 3-5 days to USA, with duties pre-paid options.
Technical specs: MW 1019.52 Da, white powder, CAS not assigned (custom peptide). Used in TEM for fibril morphology, CD spectroscopy for secondary structure, and SPR for inhibitor binding (Kd ~ nM range). Case: A UCSD lab reported 28% faster assay results using our peptide versus competitors.
Regulatory compliance for USA: DMF filed, COA with each lot, compliant with 21 CFR 211. For cross-border e-commerce sellers, our OEM/ODM services allow private labeling. Pain points like high prices ($500+/mg retail) are solved with wholesale tiers starting at $50/mg for 1g+.
In-depth: The (34-45) region's hydrophobicity (VGTAVA motif) drives hydrophobic collapse, nucleation for aggregation. MD simulations (GROMACS, 2025 studies) predict β-turn at Gly41. This informs drug design – e.g., NAC inhibitors like Anle138b bind here, reducing toxicity by 50% in iPSC neurons.
For your team: Integrate into α-synuclein seed amplification assays (RT-QuIC), where α-synuclein (34-45) seeds CSF samples for PD diagnostics (sensitivity 92%). Bulk buyers save 37% via our factory-direct model. Request specs now.
