產品名稱：Bevacizumab
產品描述：
| 產品描述 | Ipilimumab anti-CTLA-4) is an immunomodulatory monoclonal antibody directed against the cell surface antigen CTLA-4 and also a type of immune checkpoint inhibitor.Bevacizumab a humanized monoclonal antibody specifically binds to all VEGF-A isoforms with high affinity. |
| 激酶實驗 | The binding kinetics of Bevacizumab or FD006 to VEGF is measured using Bio-Layer Inter-Ferometry on Octet RED. The assay is conducted at 30°C in PBS buffer. Sensor tips are pre-wet for 15 mins in buffer immediately prior to use, and the microplates are filled with 200 μL per well of diluted samples (VEGF) or buffer and agitated at 1000 rpm. The anti-human IgG biosensor are pre-saturated with Bevacizumab or FD006 (10 μg/mL) and washed in buffer for 120 seconds, and then transferred to VEGF at concentrations of 10 μg/mL, 3 μg/mL and 1 μg/mL. The VEGF association and dissociation rates are measured for 5mins and 10mins, respectively. The Kinetics parameters (Kon and Koff) and affinities (KD) are calculated from a non-linear global fit using the Octet analysis software. Multiple independent measurements are performed[2]. |
| 細胞實驗 | Human umbilical vein endothelial cells (HUVECs) (1×104 cells/100 μL/well) are seeded in 96-well plates and cultured at 37 for 14 h with Endothelial Cell Medium supplemented with 5% heat-inactivated FCS, 100 U/mL Penicillin, 100 U/mL Streptomycin, and endothelial cell growth supplement. After low-serum starvation overnight, cells are treated with different concentrations of FD006 or Bevacizumab which are pre-incubated with 10 ng/mL VEGF for 30 minutes and incubated at 37, 5% CO2 for 72 hours. Then, 10 μL CCK8 is added to each well and incubated for another 4 hours. The absorbance is measured by spectrophotometer at 450 nm to determine the cell viability[2]. |
