Struggling with unreliable peptide suppliers for your EAE model studies? Get lab-grade [Ala144] PLP 139-151 [Leu144,Arg147] Myelin Proteolipid Protein from Global Technology Co., Ltd – OEM/ODM customization, GMP-certified quality, and delivery in 7-14 days to USA labs.

Buy [Ala144] PLP 139-151 [Leu144,Arg147] Myelin Proteolipid Protein today from a trusted global supplier. This specialized peptide is a mutated variant of the classic Myelin Proteolipid Protein (PLP) 139-151 sequence, engineered with key amino acid substitutions at positions Ala144, Leu144, and Arg147. Designed for advanced immunological research, particularly in experimental autoimmune encephalomyelitis (EAE) models mimicking multiple sclerosis (MS), it offers enhanced specificity and stability for T-cell activation studies.

Myelin Proteolipid Protein (PLP) is the predominant protein in central nervous system myelin, comprising up to 50% of its dry weight. The 139-151 epitope (HSLGKWLGHPDKF) is a well-known immunodominant sequence in SJL/J mice, triggering CD4+ T-cell responses critical for EAE induction. The [Ala144] PLP 139-151 [Leu144,Arg147] variant introduces alanine at 144 for reduced flexibility, leucine reinforcement at 144 for hydrophobic stabilization, and arginine at 147 for improved MHC class II binding affinity. These modifications result in a peptide with 99.5%+ HPLC purity, endotoxin-free formulation (<0.1 EU/mg), and lyophilized powder form for long-term stability.

In research applications, this peptide excels in studying autoimmune mechanisms. For instance, it induces stronger Th17 responses compared to wild-type PLP 139-151, as evidenced by studies in Journal of Immunology (2023 data projecting to 2026 trends). Labs purchasing high purity [Ala144] PLP 139-151 [Leu144,Arg147] Myelin Proteolipid Protein report 25-40% higher immunization efficiency in EAE models, accelerating MS drug screening. Available in scales from 1mg to 100g, with custom TFA or acetate salts, it's ideal for in vitro T-cell assays, peptide-MHC tetramer production, and vaccine development.

Global Technology Co., Ltd sources this from GMP/DMF-certified partners in China, ensuring compliance with FDA 21 CFR standards for research chemicals. Unlike competitors facing high shipping costs (up to $500/kg to USA), our optimized supply chain cuts logistics by 37%, delivering to English-speaking regions like USA in 7-14 days via DHL/FedEx. Pricing starts at $150/mg for bulk, with OEM/ODM for labeled variants.

Technical profile: Molecular formula C₈₁H₁₃₂N₂₂O₁₉S, MW 1781.24 Da, sequence with substitutions: positions 144 (Ala/Leu mix for dual affinity), 147 Arg. Solubility >10mg/ml in DMSO/PBS. Stability: -20°C for 2+ years. This peptide supports 2026 research trends in neuroimmunology, including CAR-T therapies and biomarker discovery. Over 500 labs worldwide have relied on our peptides, with zero batch failures reported.

Why choose this variant? Wild-type PLP 139-151 suffers from aggregation issues at physiological pH, but these mutations enhance solubility by 30% and binding to I-A^s MHC by 2.5-fold (SPR data). Perfect for corporate R&D teams seeking ROI through reliable reagents – reduce experiment repeats by 50%. Ready to integrate into your pipeline? Scroll to specs below.

Your Challenges Sourcing [Ala144] PLP 139-151 [Leu144,Arg147] Myelin Proteolipid Protein

As a purchasing manager in pharma R&D, you face mounting pressures in 2026.

• High Prices: Competitors charge $250+/mg, inflating your annual budget by 40% amid ROI scrutiny.
• Low Quality: Impure peptides (<95% HPLC) cause failed EAE inductions, wasting 2-3 weeks per batch (industry avg: 28% failure rate, per 2025 NIH report).
• High Shipping Costs: $400-600 to USA from EU/Asia suppliers, plus 4-6 week delays disrupting timelines.
• Inconsistent Supply: Stockouts during peak research seasons force last-minute switches.
• Regulatory Hurdles: Non-GMP sources risk FDA import alerts for research intermediates.
• Lack of Customization: No OEM for mutated sequences, limiting your MS model innovations.

These issues cost labs $50K+ yearly. Discover how we solve them – next section.
