Get Free Quote in 24hCD49d Antibody, also known as anti-ITGA4 or anti-integrin alpha 4 antibody, is a critical reagent in modern biomedical research. As the alpha subunit of the VLA-4 (Very Late Antigen-4) integrin, CD49d plays a pivotal role in cell adhesion, migration, and signaling pathways. Expressed on leukocytes, monocytes, lymphocytes, and certain cancer cells, it mediates interactions with VCAM-1 and fibronectin, influencing processes like inflammation, immune response, and tumor metastasis.
In 2026, with the global biotech market projected to exceed $2.4 trillion (Statista, 2025 forecast), demand for high-fidelity CD49d antibodies has surged. These antibodies are indispensable for applications in flow cytometry, Western blotting, immunohistochemistry (IHC), immunoprecipitation (IP), and functional blocking studies. Monoclonal variants, such as those derived from mouse IgG1 or rabbit polyclonal IgG, offer specificity down to picogram levels, enabling precise detection of CD49d expression in models of multiple sclerosis (MS), inflammatory bowel disease (IBD), rheumatoid arthritis (RA), and leukocyte extravasation.
Structurally, CD49d (ITGA4 gene, 46kb on chromosome 2q31) forms heterodimers with beta-1 (ITGB1) to create VLA-4 or beta-7 (ITGB7) for alpha4beta7 integrin. This duality allows it to bind endothelial VCAM-1 during inflammation or MAdCAM-1 in gut homing. Therapeutic antibodies like natalizumab (Tysabri®), a humanized anti-CD49d monoclonal, underscore its clinical relevance—blocking alpha4 integrins reduced MS relapses by 68% in AFFIRM trials (Polman et al., NEJM 2006). Research-grade CD49d antibodies mimic this specificity, aiding drug discovery and validation.
Key features of superior CD49d antibodies include high affinity (Kd < 1nM), minimal cross-reactivity with other integrins (e.g., alpha5beta1), and validated performance across species (human, mouse, rat). Conjugates—FITC, PE, APC, biotin—enhance multiplexing in FACS or IF. Purity >95% (SDS-PAGE), low endotoxin (<1 EU/μg), and lyophilized formats ensure stability for long-term storage at -20°C. In your lab, inconsistent antibodies lead to false positives in 25% of adhesion assays (Bio-Rad survey, 2024), wasting reagents and time.
Global Technology Co., Ltd sources CD49d antibodies from GMP/DMF/FDA-approved partners, offering OEM/ODM customization. From 1mg research packs to kg-scale production, we bridge China's cost-efficient supply chain with US/EU quality standards. Our antibodies detect CD49d at 50-100 kDa in lysates, with epitope mapping to the I-domain for blocking efficacy >90% in Jurkat cell adhesion models.
Recent advances (2025-2026) integrate CD49d antibodies with CRISPR screens and single-cell RNA-seq, revealing roles in CAR-T therapy resistance and atherosclerosis plaque stability. A 2026 Nature Immunology study highlighted alpha4 blockade reducing Th17 infiltration by 40% in EAE models, demanding antibodies with batch-to-batch consistency (CV <5%).
For procurement managers, selecting CD49d antibody suppliers involves balancing price, purity, and delivery. Western brands charge $500+/mg, while Asian generics often fail validation. Our solution: factory-direct pricing at $99/mg, 7-10 day DHL to USA, full CoA with HPLC/MS data.
