- 50nM human huB7-H4-His protein diluted in the same buffer was injected at a flow rate of 10uL/min. After injection, all were regenerated with the regeneration reagent in the kit. Track the antigen-antibody binding kinetics for 3 minutes and track the dissociation kinetics for 10 minutes.
- MX-1 cells are used for evaluation.
- MX-1 cells were trypsinized (washed with PBS first, 37°C, about 2min), collected and resuspended in pre-cooled FACS buffer, adjusting the cell concentration to 1 ⁇ 10 6 cells/mL.
- Take the EP tube add 1 mL of cell suspension, centrifuge at 1500 rpm for 5 minutes, and remove the supernatant. Add 1 mL of the prepared antibody to be tested to resuspend the cells. The final concentration of the antibody is 20 ⁇ g/ml.
- 2a (2g, 17.2mmol) was dissolved in 75mL of acetonitrile, and potassium carbonate (9.27g, 67.2mmol), benzyl bromide (20mL, 167.2mmol) and tetrabutylammonium iodide (620mg, 1.68mmol) were added in sequence.
- the reaction solution was stirred at room temperature for 48 hours, filtered through diatomaceous earth, the filter cake was rinsed with ethyl acetate (20ml), the combined filtrate was concentrated under reduced pressure, and the resulting residue was purified by silica gel column chromatography with a developing solvent system C to obtain Product 5a (3.2g, yield: 90.1%).
- reaction solution was purified by high performance liquid chromatography (separation conditions: column: XBridge Prep C18OBD 5um 19*250mm; mobile phase: A-water (10mmol NH 4 OAc): B-acetonitrile, gradient elution, flow rate: 18 mL/min ), the corresponding components were collected and concentrated under reduced pressure to obtain products 5-A and 5-B (3.6 mg, 2.6 mg).
- hu2F7-exitnotecan effectively killed NCI-H929-LUC cells, indicating that in the presence of B7-H4 positive cells, hu2F7-exitnotecan has a bystander killing effect, not only Kills B7-H4 positive cells, and can kill the originally insensitive B7-H4 negative cells (see “Single Cell Group”).
