Description
Product Description
Bevacizumab (CAS 216974-75-3) is a recombinant humanized monoclonal antibody specifically targeting vascular endothelial growth factor A (VEGF-A), a key mediator of angiogenesis and vascular permeability. By binding to VEGF-A, Bevacizumab prevents its interaction with VEGF receptors on endothelial cells, inhibiting downstream signaling cascades involved in angiogenic processes.
In preclinical research, Bevacizumab is used to study mechanisms of tumor angiogenesis, vascular remodeling, and VEGF-dependent cell signaling. It is particularly valuable in evaluating the role of VEGF-A in cancer progression, endothelial cell proliferation, and migration in both in vitro and in vivo models. By blocking VEGF-A, researchers can examine changes in microvascular density, vessel maturation, and tumor microenvironment interactions.
Bevacizumab’s high specificity allows mechanistic studies without significant off-target effects. Researchers employ it to investigate:
VEGF-mediated angiogenesis in tumor and normal tissue models.
Endothelial cell proliferation, migration, and tube formation assays.
Tumor progression and vascularization in xenograft and syngeneic animal models.
Synergistic or combinatorial effects with chemotherapy or other targeted therapies.
The antibody is provided as a lyophilized, high-purity powder (≥99%), suitable for laboratory research. It is soluble in PBS or other physiological buffers, facilitating in vitro and in vivo applications. Each batch is verified using ELISA, SDS-PAGE, and Western blot to confirm activity, purity, and structural integrity.
Bevacizumab is also utilized as a mechanistic probe to explore VEGF-A-dependent signaling, including the PI3K/AKT, MAPK/ERK, and NF-κB pathways. Preclinical studies can leverage this compound to model anti-angiogenic therapy, evaluate compensatory vascular signaling, and investigate endothelial cell responses in tumor and tissue microenvironments.
Its application extends to research on vascular biology, tumor microenvironment modulation, and translational studies evaluating novel anti-angiogenic strategies. Bevacizumab’s specificity, reproducibility, and high purity make it an essential reagent for mechanistic studies in oncology and angiogenesis research.

Mechanism of Action
Bevacizumab is a recombinant humanized monoclonal antibody that specifically binds to vascular endothelial growth factor A (VEGF-A), preventing it from interacting with VEGF receptors (VEGFR-1 and VEGFR-2) on endothelial cells.
This blockade inhibits VEGF-mediated signaling pathways, including PI3K/AKT, MAPK/ERK, and NF-κB, leading to reduced endothelial cell proliferation, migration, and tube formation. In preclinical cancer models, this mechanism suppresses angiogenesis, tumor microvascular density, and vascular permeability, making Bevacizumab a critical tool for studying VEGF-dependent processes and anti-angiogenic therapies.
