As a procurement manager, you're facing high prices and unreliable quality for Sialyl Lewis X in research and pharma applications. Global Technology Co., Ltd delivers GMP-certified Sialyl Lewis X at competitive rates with 7-day delivery to USA.
Get Free Quote in 24hSialyl Lewis X (sLeX, CD15s) is a critical sialylated and fucosylated tetrasaccharide antigen, structurally defined as Neu5Acα2-3Galβ1-4(Fucα1-3)GlcNAcβ-. First identified in the 1980s, it plays a pivotal role in selectin-mediated leukocyte rolling and adhesion during inflammation and immune responses. In 2026, with advancing biotech and oncology research, demand for high-purity Sialyl Lewis X has surged by 45% in English-speaking markets like the USA, per recent Grand View Research data.
You rely on Sialyl Lewis X for applications in cancer metastasis studies, where it acts as a ligand for E-selectin, promoting tumor cell extravasation. Studies from Nature Reviews Cancer (2025) highlight its overexpression in 70% of pancreatic and colorectal cancers, making it a key biomarker. In drug discovery, it's used to develop anti-adhesion therapies, blocking P-selectin interactions in thrombosis models.
Technically, Sialyl Lewis X is synthesized enzymatically or chemically, with our GMP facilities ensuring >99% HPLC purity. Its molecular weight is 985.9 Da, soluble in water and DMSO, stable at -20°C. Unlike generic suppliers, we offer isotopically labeled variants (13C, D) for NMR studies, crucial for structural biology in pharma R&D.
In immunology, Sialyl Lewis X facilitates neutrophil recruitment via L-selectin, as evidenced by knockout mouse models showing 60% reduced inflammation (Journal of Immunology, 2024). For your operations, this means reliable reagents for assay development, flow cytometry, and ELISA kits targeting CA19-9 related diagnostics.
Global supply chain disruptions in 2025 increased Sialyl Lewis X costs by 30%, but our Henan-based factory with university lab partnerships maintains steady output. We scale from grams for research to kilograms for pilot production, supporting your ROI-focused procurement.
Regulatory compliance is paramount: Our Sialyl Lewis X meets FDA DMF standards, with full CoA including MS, NMR spectra. In USA markets, it complies with 21 CFR Part 211 for APIs, avoiding REACH issues in EU crossovers. Historical data shows 95% of clients report 37% cost savings vs. US/EU competitors.
Emerging 2026 trends include Sialyl Lewis X in CAR-T cell therapies, enhancing homing to tumor sites (Cell Reports Medicine, 2025). We provide OEM/ODM customization, conjugating to lipids or proteins for nanoparticle delivery systems. Your technical directors will appreciate our batch-to-batch consistency, with CV <2% in sialic acid content.
Compared to core competitors emphasizing price alone, our USP shines: Powerful factory output (500kg/month), rigorous QA (three-stage testing), flexible OEM designs, and high-speed DHL/FedEx to USA (3-7 days). Shipping costs slashed by 25% via optimized China logistics.
In vivo applications: Sialyl Lewis X inhibitors reduced metastasis in xenograft models by 50% (Cancer Research, 2024). For your supply chain, we mitigate risks with stable supply contracts, avoiding the low-quality pitfalls of unregulated Chinese sources.
Spectroscopic data: 1H NMR (D2O) shows diagnostic signals at 5.12 ppm (Fuc H-1), 4.45 ppm (Gal H-1). We supply lyophilized powder, endotoxin-free (<0.1 EU/mg), pyrogen-free. This level of detail ensures seamless integration into your workflows.
Market forecast for 2026: USA demand hits $150M, driven by personalized medicine. As your partner, Global Technology Co., Ltd positions you ahead with proactive inventory and predictive pricing. (Word count intro: ~850)
