This product is a recombinant mouse antibody that recognizes VEGFA. G6-31 recognises a VEGF epitope which is conserved between human and mouse VEGF and overlaps with the receptor binding surface.

Western blot analysis of HPAB-0330CQ was performed by loading
0.4 µg (lane 1), 0.8 µg (lane 2) and 1 µg (lane 3) VEGFA antigen onto a 12% Tris-HCl polyacrylamide gel. Proteins were transferred to a CN membrane and blocked with 5% skim milk for at least 1 hour. Membranes were probed with Anti-VEGFA Antibody (HPAB-0330CQ) at a dilution of 1:1000 overnight at 4°C on a rocking platform. Then probed with goat anti-mouse IgG HRP secondary antibody at a dilution of 1:5,000 for one hour. Chemiluminescent was detected.

ELISA analysis of HPAB-0330CQ (Lot#CB2403J02L) was performed by coating with VEGFA antigen. Then blocked with BSA, and incubated with Anti-VEGFA Antibody (HPAB-0330CQ-L) at a starting concentration of 2.5 µg/mL. The HRP-conjugated goat anti-mouse IgG as a secondary antibody. Detection was performed using TMB substrate and stopped with sulfuric acid. The absorbances were read on a spectrophotometer at 450 nm.

Shen, Jingjing, et al. "Eyedrop-based macromolecular ophthalmic drug delivery for ocular fundus disease treatment." Science advances 9.4 (2023): eabq3104. https://doi.org/10.1126/sciadv.abq3104
This study focuses on developing an innovative delivery system for macromolecular ophthalmic drugs to treat ocular fundus diseases using eyedrop formulations. Traditional treatments like intravitreal injections present risks such as infections and retinal detachment. This research introduces a penetrating carrier based on fluorocarbon-modified chitosan (FCS), which can self-assemble with proteins to form nanocomplexes. These nanocomplexes effectively traverse ocular barriers to reach the posterior eye segments, demonstrating superior therapeutic responses in mouse models of choroidal melanoma and choroidal neovascularization compared to conventional methods. The FCS/anti-PDL1 and FCS/anti-VEGFA eyedrops induced stronger antitumor immune responses and inhibited vascular proliferation, respectively, showcasing the potential for at-home treatment of various eye diseases.
In this study, Creative Biolabs provided crucial therapeutic antibodies that were integral to the research. Specifically, they supplied anti-VEGFA (Cat#: HPAB-0330CQ), which was used in the formulation of FCS/anti-VEGFA nanocomplexes for treating choroidal neovascularization. This antibody played a pivotal role in achieving comparable therapeutic effects to intravitreal injections, thus validating the efficacy of the new delivery system. The contributions of Creative Biolabs significantly advanced the study, highlighting the potential for noninvasive, effective treatment options for ocular diseases.
