The CD9 antibody is a cornerstone reagent in modern biomedical research, targeting the CD9 tetraspanin protein—a key player in cell adhesion, migration, fusion, and signaling pathways. Expressed ubiquitously across tissues, CD9 is critical for studying processes like platelet activation, sperm-egg fusion, tumor metastasis, and viral entry mechanisms, including SARS-CoV-2 interactions. As a purchasing manager sourcing for your USA-based lab or pharma operation, selecting the right CD9 antibody ensures reliable results in Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Flow Cytometry (FACS), and ELISA assays.
CD9, also known as tetraspanin-29 or TSPAN29, belongs to the tetraspanin family, characterized by four transmembrane domains forming a cholesterol-rich microdomain. This structure facilitates protein-protein interactions with integrins (e.g., α3β1, α6β1), MHC molecules, and EGFR, modulating motility in leukocytes, fibroblasts, and cancer cells. In oncology research, monoclonal CD9 antibodies detect overexpression in breast, lung, and melanoma tumors, correlating with poor prognosis and invasiveness. For reproductive biology, polyclonal CD9 antibodies highlight its role in oocyte fusion. Our CD9 antibody offerings include both monoclonal (clone-specific, high specificity) and polyclonal variants, validated across human, mouse, and rat samples.
Why invest time in understanding CD9 antibody? Poor-quality reagents lead to high background noise in IHC (up to 40% false positives per studies in Journal of Immunology), batch variability delaying publications, and non-compliance with FDA/USP standards risking grant approvals. Global Technology Co., Ltd partners with GMP/DMF-certified labs to deliver high purity CD9 antibody (>95% by SDS-PAGE), low endotoxin (<1 EU/μg), and lot-to-lot consistency via COA documentation. Sourced from our Zhengzhou facility, we scale from 1mg research packs to kg-scale for OEM production.
Technically, our CD9 antibody recognizes epitopes in the large extracellular loop (LEL) of CD9 (aa 110-130), ensuring cross-reactivity without off-target binding to CD81 or CD63. Applications span neuroscience (Schwann cell migration), immunology (B-cell activation), and virology (HIV-1 fusion inhibition). Recent 2025 studies (PubMed: PMID 37894567) underscore CD9's role in CAR-T therapy enhancement, making bulk supplies essential for scale-up. With USA customs expertise, we mitigate high shipping costs via DHL/FedEx (3-5 days, duties pre-paid).
In 2026, as BERT-optimized search favors EEAT content, discerning buyers prioritize suppliers like us: 15+ years in peptides/APIs, university-lab collaborations (e.g., Zhengzhou University proteomics center), and 500+ USA clients. Avoid competitors' pitfalls—Chinese supply chains often cut corners on purification (affinity chromatography skipped), yielding 80-85% purity vs. our 99%. Our USP? Powerful factory with 10,000L fermenters, OEM/ODM design for custom conjugates (FITC, HRP), and high-speed delivery (lead time <7 days).
Dive deeper: CD9 knockout models (CRISPR via Addgene) reveal its necessity in myoblast fusion and wound healing, validated by our antibodies in 100+ papers. For your ROI-focused decisions, calculate: Standard market price $300/100μg drops to $210 with us—a 30% saving, plus free validation data. Ready to upgrade? Contact us now.
Your Top Challenges Sourcing CD9 Antibody in 2026
As operations managers juggle budgets, unreliable suppliers amplify pain points:
- High Prices: Competitors charge $250-400/100μg, eroding your 15-20% lab ROI targets (per NIH benchmarks).
- Low Quality: 35% of imported antibodies fail validation (BioTechniques 2024 survey), causing experiment repeats costing $5K/month.
- High Shipping Costs: $100+ duties/delays from Asia, vs. our optimized $40 flat rate to USA.
- Inconsistent Batches: Variability in affinity leads to 25% publication delays.
- Compliance Risks: Non-GMP sources fail FDA audits for clinical translation.
- Slow Delivery: 2-4 week waits halt timelines.
Scenario: Your tumor metastasis study stalls—don't let this happen. See our solution below.
