Application Notes | This antibody was evaluated by ELISA, Flow cytometry (FC), Neutralization assay and Surface plasmon resonance (SPR). The ELISA was done by using the IgG1 antibody. For Flow cytometry, the transfected cells were incubated with 1 µg/mL the IgG at 4°C for 30 min. The neutralization ability to S-Fuse was measured by neutralization assay with IC₅₀ value of 0.95 ng/mL. The affinity of antibody was determined by SPR with 10 μg/mL IgG injected over sensor surfaces. |
