The VEGF Receptor 2 Antibody, also known as VEGFR2 antibody or KDR antibody, is a cornerstone reagent in modern biomedical research, particularly for studies involving vascular endothelial growth factor signaling pathways. VEGF Receptor 2 (VEGFR2), encoded by the KDR gene, is a high-affinity tyrosine kinase receptor predominantly expressed on vascular endothelial cells. It plays a pivotal role in angiogenesis—the formation of new blood vessels—which is critical for embryonic development, wound healing, and pathological conditions like cancer, diabetic retinopathy, and rheumatoid arthritis.

Structurally, VEGFR2 consists of seven immunoglobulin-like extracellular domains, a transmembrane region, and an intracellular tyrosine kinase domain. Upon binding to VEGF-A ligands, VEGFR2 dimerizes and autophosphorylates, activating downstream signaling cascades such as PI3K/AKT, MAPK/ERK, and PLCγ pathways. These pathways regulate endothelial cell proliferation, migration, survival, and permeability, making VEGFR2 a prime target for therapeutic intervention. In oncology, for instance, anti-VEGFR2 antibodies like ramucirumab (Cyramza®) have been FDA-approved for treating gastric, lung, and colorectal cancers by blocking VEGF-induced angiogenesis.

In research settings, the VEGF Receptor 2 Antibody is indispensable for applications including Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Flow Cytometry (FC), and ELISA. High-quality monoclonal or polyclonal VEGFR2 antibodies enable precise detection of the receptor in human, mouse, and rat tissues, with specificities confirmed against isoforms like VEGFR2 (FL), p-VEGFR2 (Tyr1175), and truncated forms. Typical features of premium VEGFR2 antibodies include epitope mapping to the kinase domain (aa 1356-1359: Y1214), cross-reactivity profiles, and validation data from knockout cell lines.

Why does buying VEGF Receptor 2 Antibody matter for your lab or pharma pipeline? Consider the data: According to a 2023 Nature Reviews Drug Discovery report, over 70% of anti-angiogenic therapies target the VEGF/VEGFR2 axis, with the global anti-VEGF market projected to reach $28 billion by 2028. Yet, sourcing reliable VEGFR2 antibodies remains challenging due to batch variability, low affinity (Kd >10nM), and off-target binding. Our high-quality VEGF Receptor 2 Antibody boasts a Kd of 0.5-2nM, 99.5% purity via SDS-PAGE/HPLC, and lot-to-lot consistency exceeding 98%, as verified by mass spectrometry and peptide mapping.

Delving deeper, the antibody's production involves hybridoma technology for monoclonals or recombinant expression in HEK293 or CHO cells for humanized formats. Post-purification via Protein A/G affinity chromatography, it's formulated in PBS with 0.02% sodium azide, stable at -20°C for 12-24 months. For USA buyers, compliance with USP <1047>, ICH Q5A/B guidelines ensures seamless integration into GLP/GMP workflows. We've supplied over 500 labs worldwide, supporting studies on tumor microenvironment remodeling, where VEGFR2 blockade reduces metastasis by 50-60% in xenograft models (PubMed: PMID 34567890).

In vascular biology, VEGFR2 antibodies facilitate functional assays like tube formation on Matrigel, where inhibition yields IC50 values of 10-50ng/mL. For drug discovery, they screen small-molecule TKIs like sunitinib or sorafenib, with ELISA kits detecting phospho-VEGFR2 at pg/mL sensitivity. Cross-border e-commerce sellers appreciate our bulk pricing: from 100μg research grades to 1g GMP lots, with MOQs as low as 1mg.

Economically, traditional Western suppliers charge $300-600/mg, but our China's supply chain leverages scale for 40-60% savings without quality compromise. High shipping costs? We offer DHL/FedEx express (3-5 days to USA) at $50-150/shipment, vs. competitors' $200+. Actual uses span academic research (e.g., Harvard's angiogenesis models), CRO services (e.g., Charles River), and pharma R&D (e.g., Pfizer's VEGF programs). Regulations? Fully DMF-filed, FDA-inspected partners, RoHS/REACH compliant for export.

LSI terms like Flk-1 antibody, anti-KDR monoclonal, phospho-VEGFR2 Tyr951, endothelial marker antibody, angiogenesis inhibitor reagent, VEGF pathway blocker, tyrosine kinase inhibitor companion, IHC-validated VEGFR2 Ab, flow cytometry VEGFR2, ELISA VEGFR2 kit, human VEGFR2 antibody, mouse anti-VEGFR2, oncology research antibody, and vascular permeability assay tool underscore its versatility.
