Frequently Asked Questions

What is ADCC?
ADCC stands for antibody-dependent cell-mediated cytotoxicity, a mechanism by which antibodies mediate immune responses.
How quickly can results be obtained using this protocol?
Results can be obtained within one day using the simple mix and read protocol.
What are the advantages of using the ADCC bioassay kit?
The kit allows for rapid testing, high accuracy, and mass screening of therapeutic antibodies.
Why is the signal-to-noise ratio important?
A high signal-to-noise ratio ensures accurate evaluation of therapeutic antibodies, minimizing false results.
What is the purpose of this study?
The study aims to present a new method for testing the efficacy of antibody drugs in cancer treatment.

Here, we present a protocol for an antibody-dependent, cell-mediated cytotoxicity (ADCC) assay using an ADCC bioassay kit. This method offers a valuable tool for elucidating the ADCC mechanism and evaluating the therapeutic potential of antibodies in cancer immunotherapy.

It is well known that antibody dependent, cell mediated cytotoxicity is an important mechanism by which antibody exert immune mediated certain effects. So we want to find a better method to test the efficacy of an antibody drug in cancer treatment, by using ADCCSA. The protocol is rapid and straightforward.

By using simple mix and read protocol, we can obtain the result within one day, thereby expediting the research. By using ADCC bioassay, we can perform mass screening of therapeutic antibody drug more accurately. The signal to noise ratio of the assay is high, which can help in accurate evaluation of the therapeutic antibody.
