By binding VEGF-A isoforms, Bevacizumab prevents their interaction with VEGFR-1 and VEGFR-2 receptors, blocking downstream signaling pathways such as PI3K/Akt, MAPK/ERK, and PLCγ. This inhibition reduces endothelial cell proliferation, migration, tube formation, and survival.The sterile solution format allows direct application in endothelial cell culture, 3D vascular organoids, microfluidic angiogenesis models, and tumor microenvironment assays. Researchers can use Bevacizumab to dissect VEGF-dependent mechanisms, evaluate anti-angiogenic therapeutics, and model vascular normalization in preclinical studies. Its high purity and GMP-grade production ensure reproducible outcomes across laboratories, making it suitable for bulk research, OEM projects, and high-throughput experimentation.Bevacizumab’s structural integrity, including proper glycosylation and Fc region configuration, ensures stable VEGF-A binding, minimal aggregation, and preserved biological activity. The solution has been validated for low endotoxin levels, sterility, and consistent bioactivity, supporting long-term research workflows. Its applications include tumor angiogenesis inhibition, endothelial permeability modulation, vascular sprouting studies, and organoid vascular network formation.BevacizumabProduct SpecificationsParameterDetailsChemical Name / SynonymsBevacizumab, rhuMAb VEGF, Avastin (research use)CAS Number216974-75-3Molecular FormulaC₆₅₀₀H₁₀₀₀₀N₁₇₀₀O₂₀₀₀S₄₀ (approx.)Molecular Weight~149 kDaPurity≥99% (HPLC-SEC verified)AppearanceClear to slightly opalescent sterile solutionDosage FormSterile solutionSolubilityFully soluble in aqueous buffers, physiological pHConcentrationCustomizable (1–25 mg/mL)Storage Temperature2–8°CStabilityMaintains VEGF-A binding and monomeric state during shelf lifeAnalytical MethodsHPLC-SEC, SDS-PAGE, LC-MS, bioassaysMechanistic TargetVEGF-AStructural CategoryHumanized monoclonal IgG1 antibodyApplicationsEndothelial assays, tube formation, organoid vascularization, microfluidic angiogenesis modelsBatch ConsistencyGMP-compliant production and QC verifiedRegulatory NotesResearch-use only, not for human or veterinary useOriginRecombinant expression in mammalian cellsAdditional DataCoA, endotoxin ≤0.1 EU/mg, functional bioactivity confirmedMechanism of ActionBevacizumab binds VEGF-A isoforms with high affinity, preventing interaction with VEGFR-1 and VEGFR-2 on endothelial cells. This blockade inhibits receptor dimerization and downstream phosphorylation events, suppressing pathways that control cell proliferation, migration, tube formation, and survival. The antibody also reduces vascular permeability by stabilizing endothelial tight junctions, and it impairs sprouting angiogenesis in both 2D and 3D in vitro models.In tumor microenvironment research, Bevacizumab reduces neovascularization, normalizes vessel structure, and modulates extracellular matrix interactions. Its sterility and high purity allow reproducible applications in organoids, co-culture systems, and microfluidic models. Mechanistic studies demonstrate its efficacy in inhibiting PI3K/Akt and MAPK/ERK signaling, making it a robust tool for angiogenesis research, drug screening, and translational preclinical studies.Bevacizumab bulk wholesale and GMP factory OEMSide EffectsAs a research-use-only reagent, Bevacizumab may exhibit cell-line-specific cytotoxicity or off-target effects when used at high concentrations. In vitro, it can induce endothelial growth arrest, reduce migration, or alter tube formation in sensitive cell types. Handling precautions include using sterile techniques, avoiding repeated freeze-thaw cycles, and minimizing light exposure. Laboratory personnel should follow biosafety guidelines for recombinant antibodies.Bevacizumab is designed for experimental research; effects observed are limited to cellular and tissue models. Care should be taken to accurately titrate doses to avoid confounding experimental outcomes. Stability under recommended storage ensures consistent functional activity, reducing variability in long-term studies.KeywordsBevacizumab, CAS 216974-75-3, sterile solution, VEGF-A inhibitor, high-purity antibody, research reagent, endothelial assays, angiogenesis studies, organoid vascularization, tumor microenvironment, GMP OEM, bulk supply, recombinant monoclonal antibody, small-molecule supplier, China chemical manufacturer, high-purity chemical, laboratory reagent, preclinical research, bulk production, research-grade antibodyShipping GuaranteeBevacizumab sterile solution is shipped under cold chain conditions with ice packs or dry ice, ensuring stable temperature control throughout transit.
